Windows Mouse Button Techniques Using a mouse, the action of Clicking is pressing and releasing the left mouse button typically used when selecting an object. The Double-clicking action selects something and initiates an action, such as running a program. Right-clicking causes a context-menu to appear. A context-menu is also known as a pop-up menu.
Checking AutoCAD System Variables A few AutoCAD variables should be checked and modified if necessary before starting a ProConcrete 3D work session. Name MEASUREMENT = 1
Description Specifies whether to use the imperial or metric system (0 = imperial, 1 = metric)
PROXYGRAPHICS = 0
Controls whether proxy graphics are to be created in addition to the ProConcrete 3D objects when working with ProConcrete 3D. These proxy graphics enable viewing of the ProConcrete 3D objects when using only raw AutoCAD by itself to load the drawing. 0 = create no proxy graphics, 1 = create proxy graphics

Productivity Hints:
Check that your AutoCAD units for length are set to 0 decimal places for length. (This is normal for most steel and concrete consultants and trades.)
Units for angles are set appropriately Some ProSteel 3D and ProConcrete 3D commands will work better with the AutoCAD DYNAMIC mode set to OFF.
Checking ProSteel 3D and ProConcrete 3D Options A few default settings have to be specified for both ProConcrete 3D and ProSteel 3D as well. These settings will control the display of objects. Of course, any of these default settings for either individual or multiple objects may also be edited after the insertion. Right-click while the cursor is located within the drawing area to navigate to the “ProSteel 3D Options” dialog. First select “ProSteel 3D” on the context sensitive menu and then the flyout cell named “Options”. Check that your own settings match those shown below:

have ticked “No Dynamic Updates at Dialogs” on the ProSteel 3D Options dialog box (dialog settings page) SWITCH ON ROLLOVER and SWITCH OFF ROLLOVER: Automatically minimizes and maximizes the dialogs, allowing you to see more of your ProConcrete / ProSteel 3D model.
The ProConcrete 3D / AutoCAD Template file The installation of ProConcrete 3D will automatically create a prototype drawing, which will be used as a template for further work. This file copied to the template directory of AutoCAD during installation is cal led a template and is named “PS180_Metrisch.dwt”. Use the “PS180_Metrisch.dwt” template when starting new ProConcrete 3D drawings. This template contains a few settings specific to ProConcrete / ProSteel 3D such as text styles and dimensioning styles. If the user wishes to alter default settings, this template can be modified with the corresponding settings and saved again as a new template file e.g. CompanyInitials Metric.dwt
ProConcrete / ProSteel 3D toolbars and Icons All toolbars and icons reflect a similar appearance to that used in AutoCAD 2007/2008. Recommended ProConcrete 3D toolbars to have turned on include: The ProConcrete 3D toolbar shown above has many flyout menus. These flyout menus contain almost all other ProConcrete 3D toolbar buttons. If you prefer, you can turn off all other ProConcrete 3D toolbars, and still have access to most command via this toolbar.
The ProConcrete 3D toolbar shown above has many f lyout menus. These f lyout menus contain almost all other ProConcrete 3D toolbar buttons. If you prefer, you can turn off all other ProConcrete 3D toolbars, and still have access to most command via this toolbar.

Exercise 01-1
Create a new ProConcrete 3D Drawing
In this exercise, you learn to create a new ProConcrete 3D drawing, based on an existing template, and you will save the drawing with an appropriate name.
1. Start ProConcrete 3D by double-cl icking the corresponding ICON on the windows desktop.
2. Once AutoCAD has started, and the ProConcrete / ProSteel 3D software has completed loading, from the AutoCAD FILE pulldown menu, choose New (you could also type NEW at the command line, or use the QNEW icon located on the AutoCAD Standard Toolbar)
3. You will now see the “Select template” AutoCAD dialog box. Choose “PS180_Metrisch.dwt”. You will now be in a brand new drawing ready for you to start creating your ProConcrete 3D model for the remainder of this course.
Note:
Note: When starting ProConcrete 3D from the desktop icon, the default drawing opened is already using the template “PS180_Metrisch.dwt”. You can view the properties of the ProConcrete 3D desktop icon to check this. Right-click on the ProConcrete 3D desktop icon and check the Properties. The template used is defined after the /t argument.
4. By default AutoCAD will call this drawing Drawing2.dwg, as when you started ProConcrete, AutoCAD instantly created a new drawing for you called Drawing1.dwg. There is no need to save your drawing with a new name at this stage, as we will do this in the next chapter using some ProConcrete and ProSteel 3D tools.
Mar-10
13 Copyright © 2009 Bentley Systems, Incorporated
5. If your new ProConcrete 3D drawing has been started correctly, you should see a 3D UCSICON in the bottom left hand area of model space. As per AutoCAD, ProConcrete 3D will have created 2 paperspace layouts for you, called Layout1 and Layout2. These 2 layouts need to be set up using the AutoCAD Page Setup dialog box if you wish to have paperspace views of your 3D models.
6. Leave your drawing open, ready for the next chapter.

ProConcrete 3D & ProSteel 3D Dialog Settings Many ProConcrete 3D / ProSteel 3D dialog boxes include valuable diagrams on many tabs. The diagrams are used as a guide to help you set dialog values.
Where applicable, diagrams that are available on dialogs are generally shown in this right hand area as shown below.
TOOLTIPS: As you move over each field or button in a dialog box tab, a tooltip will general ly explain what the field or button does. Tooltips enable you to learn how to use ProConcrete 3D very quickly. Tooltips can be turned on or off from the ProSteel 3D OPTIONS dialog box. TABS: In Dialog boxes, tabs have been improved so that you can have tabs displayed “Side by Side” or “Stepped One Behind the Other” as shown below. Tabs can be set via the ProSteel 3D OPTIONS dialog box.
Mar-10
15 Copyright © 2009 Bentley Systems, Incorporated
ASSIGNMENTS: An Assignment tab has been included with many dialog boxes. You can also perform assigning of Classes, Layers, Part Families, Detai lstyles etc from the Shape dialog and the Plate dialog boxes. CALCULATOR: ProSteel 3D includes a calculator, an important tool when modeling using many of the connection type dialog boxes. To access the ProSteel 3D Calculator, right click in any cell within the dialog box. A context sensitive menu appears, from which you can pick “Insert calculated value”. The calculator will appear. After calculating, click the COPY button on the top right of the calculator to copy the value to the cell back in the dialog box. A click in any other cell will force the value to be applied to your 3D model.
Users of AutoCAD 2008 will also be aware that the AutoCAD Calculator is available by clicking the QUICKCALC icon, or by typing the command at the command line. INSERT PICKED LENGTH: An input method has been included in ProSteel 3D Version 17.2 that enables you to input a distance in a dialog cell, by picking two points on the AutoCAD drawing screen. Whi le your cursor is in a dialog box cell that requires a distance value, perform a right click and from the context sensitive right click menu that appears, choose Insert Picked Length. You will now be back at the AutoCAD drawing screen where you are asked to pick 2 points. After picking those two points, the distance between them is passed into the dialog box cell. A click in any other cell will force the value to be applied to your 3D model.

ProConcrete 3D / ProSteel 3D Menus Pulldown Menus : Two additional pulldown menus display at the top of your AutoCAD screen when ProConcrete 3D Version 17 is installed - one for ProConcrete 3D, the one for ProSteel 3D. Just like AutoCAD 2006, icons are displayed under the pulldown menus making it easier for users who prefer icon use, to learn and understand what icons are associated with ProConcrete and ProSteel commands. Right-Click Menus : Context sensitive right-click menus are an ideal way of modifying ProConcrete 3D / ProSteel 3D objects that have already been created in your building model. Just highlight an object (or many objects) first, right click after selection is complete (a longer right-click if AutoCAD’s time sensitive right-click is ON) and you will receive a menu that is relative to the object that you are dealing with. There may be one ProConcrete / ProSteel relevant command or many ProConcrete / ProSteel relevant commands available from the menus. See below for examples of right click menus.

Drawing Information Table
The Drawing Information Table is a command which behaves just like a Job Card or Project Reference Sheet. When using this command, you can populate project information within your model drawing. This information will be directly read into ProConcrete 3D part lists and ProConcrete 2D drawings. The Drawing Information Table icon is located on the Edi t toolbar. Alternatively, you could type the command DIT at the AutoCAD command line. The Drawing Information Table icon is located on the Edit toolbar. Alternatively, you could type the command DIT at the AutoCAD command line.

Exercise 02-1 Populating the Drawing Information Table In this exercise, you will populate the Drawing Information Table with values that relate to your particular project.
1. Click the “Drawing Information Table” command from the Edit toolbar and you will be presented with the ProSteel 3D Drawing Information Table dialog box. The values which we will set relate to common Project Information needed for Partl ists and Detail Drawings created from your current 3D model .
2. Use values similar to those shown below.
3. Notice the Template button on this dialog. It allows you to store information relating to common projects or favorite clients for later retrieval, or to insert previously saved values. It is good practice to save a template of your DIT information, so that it is not lost when working on several projects at once. The information in the DIT dialog box can be used to populate the drawing title blocks on all 2D drawings for this particular project. Use the Help button on the dialog to learn more about the Drawing Information Table feature. The Drawing Information Table dialog retains values used from the last session of ProConcrete 3D / ProSteel 3D.

These Workframes facilitate easy spatial 3D orientation because they can depict the basic system dimensions (e.g., axes dimensions) in the form of a design aid object as well as automatically create the associated UCS system for each of the views as defined by the Work frame. Users simply select with the mouse button to change the view to orientate UCS.
ProConcrete 3D for AutoCAD offers the parametric creation of rectangular Workframes (grid systems) that can or cannot include typical concrete structures. Automatically created Workframes can currently only be of a rectangular shape, but can include as many gridlines as needed. Gridl ines must be at 90 degree angles to each other. The Workframe grid dimensions can be typed into the relevant parts of the ProConcrete 3D Workframe dialog. Or the user can pick previously drawn AutoCAD lines to form the Workframe. Basic structure can be added automatically when using the ProConcrete 3D Workframe command. This structure can include all concrete Columns (at Grid intersections), Beams, Floors, Walls, Footing Pads and Footing Beams. Users have full control over the size of these concrete members. All concrete members as well as the Workframe grid lines are automatically placed on suitable layers, giving you full control over what is actually visible on the screen and in your finished drawings. Individual elements within a completed ProConcrete 3D Workframe can be edited or deleted after completion of the Workframe. It is possible to create multiple Workframes and their associated UCS systems within one model drawing. This requires a different group name (Structure name) for each Workframe system.

ProSteel 3D Workframes The ProSteel 3D Workframe command is also available when using ProConcrete 3D. This workframe command is especially suitable for steel buildings, but does not allow for the automatic addition of steel structure. The command allows for the creation of rectangular, wedge shaped, cylindrical or pyramid shaped workframes (grid systems).
Some predefined Workframes may also be available via the Template button within the Workframe dialog box. It is possible to create mul tiple work frames and their associated UCS systems within one model drawing. This requires a different group name (Workframe name) for each work frame system.

Exercise 03-1 Adding a ProConcrete 3D Workframe that includes basic structure In this exercise, you learn to create a rectangular Workframe that includes concrete structure as a base for the main area of your ProConcrete 3D model.
1. Open your previously started ProSteel drawing called 7092Model1.dwg, and from the ProConcrete 3D toolbar, choose the ProConcrete 3D Workframe icon.
2. When prompted at the AutoCAD command line to “Use Existing Gridlines to create Workframe” Right click (enter) to accept the default of NO. Now when asked to “Pick Origin of Workframe” Right click (an Enter) to accept the default co-ordinate system origin as a start point for your workframe. (The default world co-ordinate system origin point is 0,0,0). Click enter again to confirm the current X direction as the “X Axis of Workframe”. You should now see the ProConcrete 3D Workframe dialog box.
3. Enter the values in the ProConcrete 3D Workframe dialog as shown below. This will create and define the grid system to be used, as well as attach many of the basic concrete components.

There are several Elements listed under the Element dropdown list. Assignments can be set for each element. In this case ensure that all elements are set as per the columns as shown here.
It is important to complete all ProConcrete 3D dialog boxes, and all ProSteel 3D dialog boxes and press the OK button (check button) if you want to retain the current model with the values that you placed in the dialog cells.
4. You should now see a Workframe with structure similar to that shown in wireframe and shaded view.
Notice that all wanted concrete columns, beams, floors, and footing pads have been added to the grid system and the grid system is a 3D one. Frame lines are automatically drawn that represent the different floor levels, and beam and column setout lines. These frame lines are automatically placed on the layer “PS_FRAME” and are coloured orange. Gridlines are also automatically created as one single object known as a system line. The grids are placed on the layer “PC_OBJECT” and are coloured blue. All concrete beams, columns, floors and pads are also automatically coloured and placed on the layers “PC_BEAM, PC_COLUMN, PC_SLAB and PC_PADFOOTING”.
5. We will now manually add Gridline A and Gridline E.

Mar-10
ProSteel 3D Workframes
Draw an AutoCAD line to the front of the building that represents Gridline A. Ensure that this line is 3000 in front of Gridline B, and runs between Gridlines 1 and 3 (as shown below). Place the line on the layer “PS_OBJECT” (the ProConcrete 3D layer dedicated to system lines), and use the assigned layer colour (colour 5). Now draw a similar line to the rear of the building that represents Gridline E. Ensure that this line is 3000 beyond Gridline D, and the same length as Gridline A.
6. We will now manually add some setout lines and an arc to the right side of the building model. These setouts will be used to add more columns, beams and slabs. Draw an AutoCAD arc to the right side of the building and down at the ground level. Ensure that this arc is 6000 radius and is 180 degrees running from the Gridline B,3 intersection to the Gridline D,3 intersection (as shown below). Draw 2 additional 45 degree angled lines from the arc centrepoint to the arc perimeter (as shown below). These lines will be used for the placement of columns. Place the arc and lines on the layer “PS_OBJECT” (the ProConcrete 3D layer dedicated to system lines), and use the assigned layer colour (colour 5).
Save your drawing back to hard disk once you have completed this task.

Exercise 03-2 Adding a ProSteel 3D Workframe In this exercise, you learn to create a ProSteel rectangular Workframe as a base for the future steel framed roof area of your ProConcrete 3D model.
1. From the Utilities toolbar, choose the Workframe icon, or pick Workframe from ProSteel 3D / Additions pulldown menu.
2. When prompted for the Workframe origin point, use the point 0,0,9000 as a source (or you could Osnap to the top of the orange frame line at the Gridline B,1 intersection). Enter the X-axis as requested by pointing, with Ortho set to on. The Xaxis should be off to the right of your existing model.
3. The “WORKFRAMES” command uses a dialogue box for the input of design data. Create the Workframe using the following values:
1. Create an axis label as well to improve the orientation within the Workframe. We will make these axis labels appear slightly different than those used on the ProConcrete 3D Workframe by using different colours for the grid bubbles and text. Use the following values:

ProSteel 3D Workframes
Note: The ProConcrete 3D and the ProSteel 3D Workframes perform a similar function, however the ProConcrete 3D Workframe command allows for the automatic creation of basic concrete structure while placing the frame. All objects are automatically placed on default layers when using both Workframe commands. The result of this ProSteel 3D Workframe command can be seen in the screenshot above. You will notice that a portal frame shaped Workframe has been added to the top of the original rectangular shaped ProConcrete 3D Workframe. The two Workframes can be distinguished from each other by the fact that the ProConcrete 3D Workframe grid bubbles are coloured blue, the ProSteel 3D Workframe grid bubbles are coloured grey. Save your drawing to hard disk once more before moving on to the next section.

Selecting Views and Orientating the UCS The Location Center command (resulting in the “ProConcrete 3D Location Center” dialog box) can be used to select the views defined via the work frames. Just double click on one of the named views shown within the dialog box. Selected views are normally viewed square to that view. Selecting a view resets your AutoCAD UCS square to that view. If you prefer you can set your UCS square to the view, but remain looking at your model from an isometric vantage point. When double clicking a view shown in the tree structured dialog box, the clipping planes are activated at the same time so that only the objects within this area are visible. These clipping planes were set in the ProConcrete 3D Workframe dialog box.
A double click on any named view will set your viewpoint such that you are looking perpendicular to that view, and your UCS will be reorientated so that it is aligned to that view.
Either View or UCS align your current view to any face of any already drawn ProSteel 3D object (Shape or Plate) or to set your current UCS aligned to the face of that object.
Use these buttons to collapse or expand the tree view shown in the dialog box.
Clicking the airplane button will return you to a default isometric view.

ProSteel 3D Workframes
The dialog box shown above indicates the views associated with each of the 2 Workframes associated with our currently drawn model. Note that all views associated with the ProConcrete 3D Workframe are listed under the Zone 1 heading. Zone one was used as the Structure name. Note that all views associated with the ProSteel 3D Workframe are listed under the Roof-Area heading. Roof-Area was used as the Group name. Note also that Zone 1 views are prefixed with the words GRID or LEVEL, as was defined in the ProConcrete 3D Workframe dialog box. Grid numbers and Level numbers can clearly be seen. Level 0 is representative of the bottom level, or in our case, the Ground Floor Level. The Roof-Area views do not have prefixes, but it can clearly be seen which are X direction views and which are Z direction views.
ProSteel 3D Select View The “ProSteel 3D Select View” command can also be used to select the views defined via the work frames, or to add new views to the selection list. Selected views are normally viewed square to that view. Selecting a view means double clicking a view listed in the dialog box, and this resets your AutoCAD UCS square to that view. If you prefer you can set your UCS square to the view, but remain looking at your model from an isometric vantage point. When you select a view from the Choose View dialog box via a double-click, ProConcrete 3D places the UCS into the selected work plane and displays the 3D model as if this plane is viewed vertically. The specified clipping planes are activated at the same time so that only the objects within this area are visible. These clipping planes were set in the Workframes dialog.
A double click on this named view will set your viewpoint such that you are looking perpendicular to this view, and your UCS will be reorientated so that it is aligned to that view.
Use either of these two buttons to align your current view to any face of any already drawn ProSteel 3D object (Shape or Plate) or to set your current UCS aligned to the face of that object.
Note:

SET VIEW aligns your viewpoint so that you are looking perpendicular
at the selected view, and it sets the UCS square to that view.
SET UCS button changes the UCS orientation, it does not re-align the view.
Delete any named view from the list by highlighting that view in the list first, and then clicking the Deletes Frame button.
Create a new named view anywhere in your drawing model, by aligning your UCS to that wanted view first, and then click Create New Frame. Follow the command prompts to create the new named view.
Click this button after highlighting a view in the list to enable you to edit that Frame. You can rename a View name from here, from the DATA tab on the Workframe Properties dialog.

Exercise 03-3 Selecting views In this exercise, you learn to navigate to your Workframe selected views, with or without a relevant UCS.
1. From the ProConcrete 3D main toolbar, choose the
Location Center icon.
2. Check that your resulting ProConcrete 3D Location Center dialog box have view names that match those in the diagram below, and that the settings on the Options tab are set as shown.
3. Ensure that the VIEW button is clicked on at the bottom of the Location tab, then double cl ick the listing “GridX3”. The dialog box should now close, and you will be presented with a cl ipped view of your model at Gridl ine 3.
4. Now open the ProConcrete 3D Location Center dialog box again, and click the airplane button at the bottom of the Location tab. The dialog box will remain open, and you will see a default isometric view of your model. This should also set your UCS back to the default world UCS.
5. Now ensure that the UCS button is clicked on at the bottom of the Location tab, then double click the listing “GridX3”. The dialog box should disappear and your UCS only (not the view) should now be set square to Gridl ine 3.
6. Open the ProConcrete 3D Location Center dialog box again, and click the airplane button. Now save your drawing 7092Model1.dwg to your C:\Cad Projects\7092\Model folder.

Clipping Planes Working with a 3D model can quickly become complex, especially if many parts are spatially stacked or overlap one another. ProConcrete 3D offers a command to hide parts that may be in front of or behind the current work plane. This command is called the Clipping Plane. Facilitating the design process, only those objects that are close to the same workplane are visible which prevents the accidental manipulation of stacked shapes. The term ‘approximately’ is here used in the sense that only the objects within the cutting plane distance of 250mm specified in the “work frame” are visible to the front and rear. If one of the defined views or an object view is selected, the hide option is activated as the default setting unless the command has been deactivated globally. Sometimes you may want to look at all component parts of the model within the depth, to gain an overall orientation. For this reason, this function can be switched on and off.
Clipping planes (or cut planes) can be turned on or off, adjusted for distance, or flipped by using the Clipplane command located under the ProSteel 3D / Zoom-Views pulldown menu. Alternatively you could try the icons available under the Clip Planes Toolbar

Exercise 03-4 Creating Additional Views In these exercises, you learn to create new views that are relevant to your existing model, and can be used for your 2D output.
1.
Click the Isometric Overview 1 button to ensure that you are viewing your model from a bottom right isometric vantage point.
2. Zoom to the Gridline A area. We will create a new view that suits Gridline A. 3. Set your UCS such to align to the Gridline A side of the building model. Type the AutoCAD UCS command to do this.
4. When you are asked at the AutoCAD command line to enter an option, type 3 (for the 3 Point option).
5. You are now asked to Specify an Origin. Osnap to the left hand side of the blue line that represents Gridline A (The end nearest Gridline 1).
6. Now specify a Point on Positive Side of X Axis. Osnap to the right side of the line that represents Gridline A (The end nearest Gridline 3).
7. When asked to Specify a Point on the Positive Side of Y Axis, type 0,0,500 and press Enter to set your UCS square to Gridline A.
8.
and then
9. Click the “ProSteel 3D Select View” button again. 10. When the CHOOSE VIEW dialog displays, click the Create New Frame button at the bottom of the dialog (the button third from the left). An Enter the name of the New View dialog box appears. Type Gridl ine A in the cell of this box, and finish by clicking the OK button (the check button).
11. You are now asked at the AutoCAD command line to “Select Lower Left Corner of the Desired Window”. Osnap to the left hand side of the drawn line that represents Gridline A.
12. Next you are asked to “Select Upper Right Corner of Desired Windosw”. Answer by typing exactly @5000,6000,0. A brown rectangle (5000 x 6000 ) appears on the model, and the Choose View dialog box re-appears. This brown rectangle has automatically been placed on the

ProSteel 3D Workframes
PS_FRAME layer. You will note that your new view name appears in the lists of available views in the CHOOSE VIEW dialog.
13. Exit the dialog by pressing CANCEL. 14. Repeat Step 3, but this time we want to create a Gridline E view. 15. Align your UCS to Gridline E first. First set your UCS to World UCS, and again use the UCS 3 point option.
16. When asked to Specify an Origin, Osnap to the midpoint of the blue line that represents Gridline E. When asked to Specify a Point on Positive Side of X Axis, Osnap to the left side of the line that represents Gridl ine E (The end nearest Gridline 1).
17. When asked to Specify a Point on the Positive Side of Y Axis, type 0,0,500 and press Enter. This now sets your UCS square to Gridline E.
18. Now create the new view. When asked for a View name, type Gridline E. When the AutoCAD command prompt asks you for a lower left corner, osnap to the midpoint of the blue line that represents Gridline E.
19. For the upper right corner, answer with @5000,6000,0. When finished you will see your new view listed in the CHOOSE VIEW dialog. This new view is set to look from the rear outside of the building inwards. (It is not set to look from the inside of the building towards the outside).
20. The size of the brown rectangles that have been drawn at Gridline A and Gridline E match the size values that are to be used on our building model. But in fact these brown rectangles could have been drawn to any size, as the brown rectangles define view locations, not view sizes. ProSteel views are generally slices through your complete 3D world, not just your 3D model . So the size of the rectangle that is drawn is not relevant, it is the location of this rectangle, and its UCS orientation that is important. The rectangles are also automatically placed on the locked layer PS_FRAME. You can temporarily unlock this frame, and adjust the size of the rectangle drawn, using AutoCAD grip techniques. The rectangle can also be relocated if necessary (only with the layer temporarily unlocked).
We will use these new views to help us continue modelling our building, and for future 2D drawings.
21. Now Save your model as 7092Model1.dwg to your C:\Cad Projects\7092\Model folder.

Columns, Beams and Footing Pads
Overview In this chapter, you learn about inserting and creating structural shapes and pads.
Objectives In this chapter, you will:
Get an overview of ProConcrete 3D Beams and Columns. Create concrete beams and columns and orientate them. Get an overview of ProConcrete 3D Footing Pads.
Create concrete pads and orientate them. This manual presents fundamental concepts you need to know about the modeling process in ProConcrete 3D. The tutorial is not necessarily best practice of structural concrete design but focuses on using various ProConcrete 3D commands.

41 Copyright © 2009 Bentley Systems, Incorporated
Creating Typical Columns and Beams Here are a few basics concerning the creation of basic concrete shapes, before adding extra columns and beams to your sample model. Rectangular concrete shapes can be accessed by picking the Create REC Beams or Columns button on the ProConcrete 3D main toolbar, or the ProConcrete 3D Beams and Columns toolbar. You are then presented with the following dialog:
Circular concrete shapes can be accessed by picking the Create CIR Beams or Columns button on the ProConcrete 3D main toolbar, or the ProConcrete 3D Beams and Columns toolbar. You are then presented with the following dialog: 42 Copyright Š 2009 Bentley Systems, Incorporated
Mar-10
For RECTANGULAR and CIRCULAR Shapes, type the desired dimensions in the available cells – the desired shape cross-section appears in the preview area, together with the insertion points. The selected insertion point is displayed in red. You can choose a desired material, layer, part family and display class from the drop down lists provided. There are several ways to place the wanted shapes. You may have noticed the placement buttons at the bottom of the Shapes tab. These buttons allow you to place by picking an existing line or by picking 2 points. Mar-10

Columns,
The position of the shape can be preset via the basic position, 90 degrees, etc. or directly on screen when inserting the shape if the “Orientate after Insertion” is ticked on the OPTIONS tab. Orientation of shapes can be controlled at the time of placing shapes by carefully setting options on the OPTIONS tab. Clicking this button on the Straight Shapes tab only will alter the direction that the shape is created in. You can control the start point of the shape by the use of this (a positive direction shape rather than a negative direction shape).
44 Copyright © 2009 Bentley Systems, Incorporated
Mar-10
Exercise 04-1 Inserting ProConcrete 3D Columns In this exercise, you learn to select and insert concrete column shapes, and orientate them to their desired position. 1. Close your previously created drawing. 2. Find and open the supplied AutoCAD drawing called 7092Model1a.dwg. 3. Use the AutoCAD SAVEAS command to save this drawing as 7092Model1.dwg to your C:\Cad Projects\7092\Model folder. This will replace your previously created drawing with a new one of the same name.
4. Select the Create Beams or Columns button icon
from the ProConcrete 3D main toolbar or the ProConcrete 3D Beams and Columns toolbar. 5. Insert some RECTANGULAR 500 x 500 x 6000 high columns to the vertical Workframe lines previously drawn at the Grid Intersections 1A, 2A, 1E and 2E. Use the “Insert by Line” button on the Shapes tab to place the columns, and ensure that your insertion point shown on the diagram to the right side of the dialog is set to the middle insertion point of the column. The wanted insertion point highlights in red on the diagram when clicked. Use the values shown in the dialog box below.
Click the Columns “Insert by Line” button as the method to place the new columns on existing vertical construction lines.
Mar-10

Columns,
6. Finish placing the columns. Press OK on the dialog. 7. Now insert some circular shaped columns to the 3 vertical construction lines that were previously drawn at the ends of the radial lines to the arced area at the right side of your building model. These circular columns should be 400 dia x 6000 high. Use the Create CIR Beam or Column button on the Shapes tab to place the columns, and ensure that your insertion point shown on the diagram to the right side of the dialog is set to the middle insertion point of the column. Use the values shown below.
8. When finished Press OK. All 7 rectangular and circular columns that have just been placed will need to be lengthened by an additional 200mm at the bottom end of each. This is to allow for eventual 200mm floor slabs to be added. The columns can then sit on footing pads which are placed below the floor slabs.
9. Click the Modify 1 button
on the Edit toolbar to open the Element Modification dialog. 10. From the Shapes tab of the dialog, set the Default Lengthen distance to 200, then click the Lengthen by Default as shown below.
46 Copyright Š 2009 Bentley Systems, Incorporated
Mar-10
Use the Lengthen by default button to lengthen the bottom ends of the 7 columns. Ensure this value is set to 200 mm.
Ticking Lengthen – Execute in Loop – will allow you to lengthen multiple columns
11. You are then asked at the AutoCAD command line to “Select Shape at End to be Modified”. Click any one of the 7 columns nearest its lower end, and the 200 additional length is added. Repeat this for all 7 columns. This can occur easily if “Execute in Loop – Lengthen” is ticked on the Options tab of the ELEMENT MODIFICATION dialog box. Finish the command with a right click to return the dialog box, and a click of the OK button.
Note: You may prefer to use AutoCAD GRIP EDITING techniques to lengthen the columns at the bottom end. If so click the appropriate column, select the bottom grip, and at the STRETCH command prompt, type @0,0,-200.

Columns,
Your building model should now look similar to that shown below.
2 rectangular columns were added to the rear side of the building model
2 rectangular columns were added to the front side of the building model
3 circular columns were added to the right side of the building model
You may notice that the columns that have been placed at grid Intersections 1A and 1E, are not yet aligned with the columns at Grid Intersections 1B, 1C and 1E.
12. Use the AutoCAD MOVE command to move these 2 columns 300mm towards Gridline 2. 13. Move the previously created horizontal construction lines at Levels 0, 1 and 2. 14. Draw new 6000 vertical construction lines at the 1A and 1E column centre points. 15. Adjust the length of any of the previously drawn horizontal construction accordingly. This will now mean that all of the column centerlines along Gridline 1 now align. You can check this by viewing a plan view of your model. A plan view can be achieved by typing the AutoCAD command PLAN. The view will be Plan to your current UCS. 48 Copyright Š 2009 Bentley Systems, Incorporated

Exercise 04-2 Inserting ProConcrete 3D Beams In this exercise, you learn to select and insert concrete column and beam shapes and orientate them to their desired position. Now we will add perimeter beams to Levels 1 and 2 for these new front and rear areas.
1. Click the Isometric Overview 1 button
, and zoom closer to the 2 new columns at Gridline A, to see the horizontal construction lines added earlier at Levels 1 and 2.
2. From the ProConcrete 3D main toolbar, click the Create Beams or Columns button
3. Insert some 400 wide x 600 deep perimeter beams to the construction lines previously drawn at Gridlines 1, 2 and A. Use the Beams, Insert by Line button on the Shapes tab to place the beams, and ensure that your insertion point shown on the diagram to the right side of the dialog is set to the top mid insertion point of the beam. The wanted insertion point highlights in red on the diagram when clicked. Use the values shown in the dialog below.
4. Also ensure that the Setdown is set to 150, to allow for a future 150mm thick slab to this area. The setdown will actually create a physical beam depth of 450 in this case, but the design depth remains as 600. 50 Copyright Š 2009 Bentley Systems, Incorporated
Mar-10
5. Finish placing the beams at Levels 1 and 2 by pressing OK on the dialog. You may notice now that the beam ends clash with the columns at Grids 1A and 2A. This is because the construction lines begin from the centre of the columns, and not the faces of these columns. This can be easily fixed using the AutoCAD GRIPS.
6. You can click any beam once to expose the AutoCAD GRIPS for that particular beam. Notice that there are only 2 grips for each beam, one at each end, generally around the midpoint of each beam end.
7. Click any one of these grips to make it active, then slide the chosen grip (with ORTHO turned on) until it is perpendicular to the required column face. You can use the AutoCAD Perpendicular OSNAP setting to achieve this.
8. Repeat this for each of the beam ends. If you are having problems confirming that the beam has been shortened correctly, then you can turn on the AutoCAD SHADE command to temporarily check for gaps. This will not however confirm any clashes which are still present. Clash detection will be dealt with in a future chapter within this training manual. The front area of your model should now look similar to that shown.
This is the layout of the new manually added beams to the front area of the model.

9. Repeat Steps 1 to 4 of this exercise, but for the rear end of the building, such that you have 3 new perimeter beams at Level 1, and another 3 at Level 2 that connect to the new columns at Grid Intersections 1E and 2E. The rear area of your model should now look similar to that shown.
This is the layout of the new manually added beams to the rear area of the model.
We will now add straight perimeter beams and radial beams near the curved area to the right side of the building model.
10. Click the Isometric Overview 1 button and Zoom to the curved area as shown below.
4 new perimeter beams will be added to these angled lines at Level 2 only.
1 new radial beam will be added to the line on gridline C at Level 2 only.
52 Copyright Š 2009 Bentley Systems, Incorporated
Mar-10
11. Now insert some 400 wide x 500 deep perimeter beams to the 4 new construction lines, and one of the previously created radial lines, at Level 2 only. There should be 5 new beams added. From the ProConcrete 3D Create Beam Column Shape command, use the Beams Insert by Line button on the Shapes tab to place the columns, and ensure that your insertion point shown on the diagram to the right side of the dialog is set to the top mid insertion point of the beam. Use the values as shown in the dialog shown below. Also ensure that the Setdown is set to 175, to allow for a future 175mm thick slab to this area. The setdown will actually create a physical beam depth of 325 in this case, but the design depth remains as 500.
12. Finish the command with the OK button on the dialog. 13. Click the Isometric Overview 1 button to perform a zoom all wireframe view of your ProConcrete 3D Model. You may notice that the beams that have just been added at Step 9 appear to clash with the rectangular and circular columns that they meet. They will need to be edited correctly, and this will be done in the next chapter of this manual. Your model should look like that shown below. Mar-10

Creating Concrete Footing Pads
Creating Concrete Footing Pads
Rectangular shaped concrete Footing Pads can be inserted into your ProConcrete 3D model by using the Create Pad Footing command. This command allows you to only add rectangular shaped footing pads to the bottom of previously created columns. These columns can be rectangular or circular. First the command asks you to pick the wanted column or columns. You are presented with the ProConcrete 3D Pad Footing dialog. Size the pad, as required, using dialog and the pads are placed. The pads are generally centered on the bottom centre of the columns. They can be offset using the dialog.
The INSERT FOR OBJECT button is used to insert the pad to the bottom of one or more columns.
The INSERT FOR POINT button is used to insert the pad at any chosen point. A column is not required when using this button. You must finish the command and exit the dialog with the OK button in order to permanently place the Footing Pads. The Footing Pads can be reinforced automatically. This will be covered in a later chapter of this manual. An intelligent link is formed between the column and the Footing Pad.

ProConcrete 3D includes many of the ProSteel 3D tools that will allow you to perform easy editing on many of the simple shapes and slabs created with ProConcrete. Many of these tools are available by clicking the Modify 1 or Modify 2 buttons on the Edit toolbar. Alternatively you can choose many of the individual tools using the Manipulate flyout menu, available from the ProConcrete 3D pulldown menu. You are presented with the Element Modification dialog. This dialog has several tabs, which contain commands for modifying concrete shapes. The tabs are displayed below.
The Position pulldown list is not 1. appropriate for concrete objects. It is The EXTEND and TRIM buttons are ideal for editing concrete beams and column ends. specifically created to help you deal with The DIVIDE and CONNECT buttons allow you to spl it a concrete beam into several flange type lengths, or connect several aligning beams together as one. These buttons also work steel shapes well on concrete columns. when performing The NOTCH command allows you to create rectangular shaped notches, recesses and polycuts. penetrations along beams, columns or through slabs. Typically leave this set to Complete.

Editing ProConcrete Columns, Beams and Slabs
The POLYCUT command will also allow you to cut penetrations through almost any ProConcrete Column, Beam, Slab, Wall or Footing. The penetrations can have many sides, even curved edges. It is normally advisable to first draw a closed AutoCAD polyline equal to the size of the penetration, and in the correct position. This polyline is then used to create the penetration. Alternatively, penetrations can be created by picking points, or by subtracting one shape from another.
These two buttons have more appeal to ProSteel 3D users, than for ProConcrete 3D users. They can be ignored for now.
Clicking once into an empty cell may change the type of diagram displayed on the right of. Diagrams are normally appropriate to the type of modification command being used. The SHORTEN buttons are ideal for editing beam/column ends.
The LENGTHEN buttons are ideal for editing beam/column ends.
The COPE button is for ProSteel users, not ProConcrete users.

Exercise 05-2 Creating Rectangular Liftpit Penetrations In this exercise, you learn to add rectangular penetrations to previously created floor slabs.
1. Close your previously created drawing. Now find and open the drawing 7092Model1b.dwg. Use the AutoCAD SAVEAS command to save this drawing as 7092Model1.dwg to your C:\Cad Projects\7092\Model folder. This will replace your previously created drawing with a new one of the same name.
2. The model on this drawing looks similar to the earlier model, except for the addition of some AutoCAD rectangles that have been added at each floor level. These rectangles will be used to create penetrations for al iftwell and stairwell area.
3. Now view your model from the Grid E, Grid 1 corner of the building by clicking the Isometric Overview 5 button . Zoom to the area near the Grid D, Grid 1 intersection, and you will notice a yellow rectangle at each floor level. These rectangles are drawn exactly level with the top each floor slab, at Level0, Level1, Level2 and Level3. The rectangle at Level0 is smaller than the others. There is also a rectangle drawn below Level0 for a future LiftPit floor slab. The rectangles are drawn in yellow colour to make them easier to find. They are also drawn on the default layer, Layer 0.
4. Now zoom to the rectangular polyline created at Level 3. Remain in an isometric view. Open the Element Modif ication dialog box with the MODIFY 1 button
.

Exercise 05-3 Adding the Liftpit In this exercise, you will edit acolumn length, then add a lift pit concrete floor slab and liftpit perimeter walls
1. Turn off the shading and view your building model from the lower left side by clicking the Isometric Overview 2 button (available on the ProSteel 3D Viewtools toolbar). Now use the AutoCAD ZOOM and ORBIT commands to view the area near the bottom of the column at the Grid 1,C intersection. This is where we will create the Liftpit.(You should already have a yellow rectangle drawn at the Liftpit slab location below Level 0.
2. The column at the Grid 1,C intersection needs to be extended 2000 deeper so that it will not clash with the Liftpit floor slab. Delete the footing pad already placed at the bottom end of this column.
3. Now use the “Lengthen by Input” command to add 2000mm extra depth to the column. The “Lengthen by Input” button
is on the Shapes tab of the ProSteel 3D
ELEMENT MODIFICATION dialog box . Select the column nearest the bottom of it when asked at the AutoCAD command line, and answer with 2000 as the modification length. Finish the command with the OK button.
4. Use the “Create Pad Footing” button
to add a new 900 x 900 x 300 deep footing pad to the now deeper column at the Grid 1,C intersection.
5. To add the Liftpit floor slab we will use the Create Slab command From the ProConcrete 3D main toolbar or the Slab toolbar, find and click the “Create Slab” button . You will now see the ProConcrete 3D Slab dialog. Fill out the values in the box as shown below:
Click the “Insert Slab by Four Points” button to create the new Liftpit slab. The size will not be 300 x 2000 as shown in the dialog, but will be determined by the four points picked. Although the Mar-10
dialog box allows for a 71 Copyright © 2009 Bentley Systems, Incorporated
Editing ProConcrete Columns, Beams and Slabs
length and width of the new slab, any values input here will be ignored, because we will be using a pick point method to determine the size of the slab. From the dialog box, click the “Insert Slab by Four Points” button to create the new slab at the existing rectangle. When asked at the AutoCAD command line to pick the four points to create the slab, OSNAP to each of the four corners of the rectangle in the order speci f ied at the command line. Your new slab should be 200mm thick, and below the rectangle. Finish the command with the OK button.
6. The new Liftpit slab currently clashes with the column that extends below the Ground Floor Level. (This may easily be seen if you SHADE your model, and ORBIT around the Liftpit area). We can perform BOOLEAN operations on the Liftpit floor slab to f ix the clash. Turn off all objects in your model, except the column, Liftpit floor slab, and footing pad in this area, by clicking the “HIDE EXCEPT” button . This command button is located on the Display Classes toolbar. Follow the prompts at the command line to pick all of the construction lines, Liftpit floor slab, column and footing pad at this area. All objects will be hidden except those picked. (Remain in wireframe mode, not shaded mode).
7. Now we will perform the Boolean operation. Click the “Subtract Intersect Body” button . It is located on the Edit toolbar (it may be hidden under another Boolean button), and on the Boolean toolbar. When prompted at the AutoCAD command line for the “Element from which other Elements should be Subtracted”, click the 200 thick liftpit slab. When prompted for the “Part to be Subtracted”, click the 600 x 600 column near the point where the clash with the slab occurs. The subtraction is now completed, the slab now has a small corner missing, allowing the column to pass.
8. Remain zoomed to the Liftpit area. We will now add the side walls to the Liftpit with the” Create Precast Panel or Wall” button . This button is located on the ProConcrete 3D main toolbar and on the ProConcrete 3D Panels and Walls toolbar. After clicking this button you will see the ProConcrete 3D Precast Panel dialog box. We will use this dialog box 4 times to place 4 walls around the liftpit. Fill out the values as shown below, then click the “Insert a Wall by Specified Points” button, located near the bottom left of the box. (Watch for the tooltips to locate the correct button). Follow the prompts at the AutoCAD command line to pick two corner points of the existing Liftpit slab. Start at a left corner and finish with the next corner to the right.

Editing ProConcrete Columns, Beams and Slabs
The “LEFT” Offset Position may need to be changed to RIGHT. This will depend on the clockwise or anticlockwise direction that you pick the wall / slab corners in. (Left for clockwise, right for anticlockwise).
Click the “Create a Panel by Specified Points” button to begin placing the new walls.
You should now see a new 200mmm thick wall along one side only of the Liftpit area. The dialog box will re-appear. Repeat the process for the other 3 walls, taking care not to overlap walls where they meet, and not to interfere with the existing column. Finish the command with the OK button. If necessary, adjust the length of walls by using the object GRIPS.
9. “The ProSteel 3D Regen” button
can now be clicked to turn on all objects that were previously turned off. This button is located on the Display Classes toolbar. This button regenerates all objects within your building model, allowing them to be visible again. The AutoCAD REGEN command does not affect ProConcrete or ProSteel objects. Also, any objects that are currently located on FROZEN or OFF layers, will not be visible after using the ProSteel 3D Regen command.
10. Click the Isometric Overview 1 button
to set the view back to an isometric view of your entire model. The diagrams below indicate what your model should now look like. You can confirm that your model is similar by use of the AutoCAD SHADE command, and the ORBIT command. You may want to delete some of the construction lines used to create the lift and stair penetrations. Remember that these are all drawn on Layer 0, the default ProConcrete construction layer. The yellow rectangles used in this chapter are on the Layer 0.

75 Copyright © 2009 Bentley Systems, Incorporated
Display Classes and Area Classes
Display Classes and Area Classes In many projects, different areas, member types, levels, zones etc. etc. can be present. To help reduce screen complexity, the abil ity to “turn off” certain user definable object sets would be very helpful. ProConcrete 3D offers this capability via the “Display Classes” and Area Classes functions.
This is the DISPLAY CLASSES toolbar. Some of the buttons shown on here are explained in the previous section. (HIDE EXCEPT and PROSTEEL 3D REGEN)
1.
The Display Classes command icon is found on the “Viewtools” toolbar, or on the “Display Classes” toolbar menu. Also you can choose Dialog, from the ProConcrete 3D / Display Classes pull down menu. Display classes are used for assigning parts by types, for example:
All shapes that are Beams
Gridline A
All shapes that are Columns All shapes that are Footing Pads and Footing Beams
All shapes that are Stairs etc, etc Display classes could also be used for assigning to Grids, i.e. Gridline B etc, etc The “ProSteel 3D Display Classes” dialog box gives you control over hiding and displaying individual parts, as well as hiding and Displaying Classes. The Area Classes command icon is found on the “Viewtools” toolbar, or on the “Display Classes” toolbar menu. Also you can choose the ProConcrete 3D pull down menu. Rebar cages and component parts spanning across construction areas, construction zones, or project areas, can be collected and combined and saved as an Area Class, which can then be displayed or hidden as needed. The “ProSteel 3D Area Classes” dialog box gives you control over hiding and displaying large or small areas of your overall 3D model. Both the Display Classes dialog box, and the Area Classes dialog box work in a similar manner. Generally when you open either of these boxes, the “Class Names” are empty. Just double click any empty Class name cel , and this will allow you to type a wanted name. Similarly, double clicking the word ON under the Status area will turn that class OFF. Al l objects assigned to that class will now be hidden. Double clicking the word OFF under the Status area will turn that class ON. Al l objects assigned to that class will now be displayed. Please note that a ProSteel 3D REGEN will not display objects assigned to a class that is OFF. You have to use the relevant Classes dialog box to turn ON those classes. Both the Display Classes dialog box, and the Area Classes dialog box have a cell that can be ticked for COMPLETE GROUPS. Grouping is a ProSteel feature that suits steel assemblies very well, but is at this stage not so suitable for concrete work. As such, for the time being you can ignore any references to GROUPS when dealing with concrete structures and rebar cages. When COMPLETE GROUPS is ticked on, you only need to pick one part of a wanted group to actually assign al l parts that belong to that group. This is of course only applicable if objects have already been GROUPED together.
76 Copyright © 2009 Bentley Systems, Incorporated
Mar-10
Display Classes and Area Classes
Double click any empty Class Name cell, and you are then able to type the wanted name for that class. Double click ON for any class, to turn display of that class OFF. Double click OFF for any class, to turn display of that class ON.
When ticked on the “Complete Groups” feature allows for easier selection of parts (More suitable for ProSteel rather than ProConcrete).
Always finish the Classes dialog box with the OK button at bottom left.
Use the slider bar if necessary to negotiate between classes where there are more than 20 classes. (You can also adjust the size of the dialog box)
There is a template button on each of the Display Classes and Area Classes dialog boxes. Use templates if needed, to save and recall classes to be used for or from other modeling projects. Templates can save you much setup time if used appropriately.
There are some common buttons to both Classes dialog boxes shown on the next page.

Exercise: Display Classes 2. Use the Display Classes command as described on the previous page to open the Display Classes dialog box.
3. Create the Display Classes as shown in the dialog box below, by double clicking any blank name on the left hand column (01). Enter the name of the new Display Class, and then move onto the next empty class.
Note: When you choose to assign parts to Display Classes will depend on the size and complexity of your 3D model. Assigning parts to Display classes is a task that may be performed many times during the creation of your ProConcrete 3D model.
It is good practice to have the Complete Groups cell ticked (applies for ProSteel rather than ProConcrete) when you assign components, you only need to pick one part of the selected group if you have already grouped objects.
4. At this stage of your project, select Footing Pads from the Display Class list and then using the “Enables the Assignment of Objects in the Selected display Class” button , select al l of the footing pads currently drawn in your 3D model. Do the same for al newly created Classes. Check that you have assigned the correct parts by choosing the Hide Class and Display Class buttons after assigning, or by double clicking the ON or OFF under status.
5. At this stage of our modeling, we have no parts to assign to Footing Beams, Steel at Roof or Stairs. You can assign any newer parts at a later stage of our project if you wish.

1. Use the Area Classes command icon
as described on the previous pages to
open the Area Classes dialog box.
2. Create the area classes as shown in the dialog box below, by double clicking any blank name on the left hand column (01). Enter the name of the new Area Class, and then move onto the next empty class. Note: When you choose to assign parts to Area Classes will depend on the size and complexity of your 3D model. Assigning parts to Area classes is a task that may be performed many times during the creation of your ProSteel 3D model. It is good practice to have the Complete Groups cell ticked (applies for ProSteel rather than ProConcrete) when you assign components, you only need to pick one part of the selected group if you have already grouped objects.
3. At this stage of your project, select Zone1A and then using the Assign button, select all of the component groups and parts for that particular Zone (all parts between Grid B and Grid C, and Gridline 1 to Gridline 3). Do the same for Zone1B (al l parts between Grid A and Grid B). Check that you have assigned the correct parts by choosing the Hide Class and Display Class buttons. Ensure that Complete Groups is ticked.
4. Note also, that parts can only belong to one display class only. This means that in instances where a part could actual ly belong to more than one class, (such as Grid B in our case) you need to make an educated decision as to which Area the part should belong to.
5. Repeat for Zone1C and Zone1D. 6. As yet we do not have parts to Assign to the Roof Area - Steel area class. You can assign any newer parts at a later stage of our project if you wish.

Part Families
Part Families
The Part Families command icon is found on the “Viewtools” toolbar, or on the “Display Classes” toolbar menu. You can also choose the ProConcrete 3D pulldown menu. Group assemblies, rebar cages and component parts spanning across construction areas, construction zones, or project areas, can be collected and combined and saved as a Part Family, such that Part Families be displayed with a unique colour, can have prefixes automat ically assigned to Position No’s when Positioning, and also have Detail Styles assigned automatically. The “ProSteel 3D Part Fami l ies” dialog box gives you control over colour display, Position No. prefixes, and DetailStyle assignments for parts and groups within your overall 3D model. Use the slider bar to view the full list of families.
Double click any empty Description cel l, and you are then able to type the wanted name for that new family. You can also apply a POS NO. PREFIX, COLOUR & DETAILSTYLE from here.
The Part Family descriptions shown in the dialog box above are there because a template has been used. You can use the template button at the bottom of the dialog box to load ??? Part Family template called System 17. Position Number Prefixes Colours and DetailStyle are automatically assigned to objects when assigning the relevant part family to those objects.

Exercise 06-3 part Families
1. Use the Part Families command icon as described on the previous page to turn on the Part Families dialog box2. Please note that at this stage that PART FAMILIES is a feature more applicable for steel structures than for concrete structures, however it can still be used on ProConcrete models to help manage display of your model, and for 2D output. Create the Part Families as shown in the dialog box below, by double clicking any blank name on the left hand column (50).
2. After double clicking you will see the Part Family Entry dialog box. Enter the name of the new Part Family, type in the Pos Prefix that you would prefer to see for Position Number Prefix, use the PALLETTE button next to Color, to assign an AutoCAD color to the Part Family, and also use the dropdown list next to Detail Style to assign DetailStyles. Positioning and DetailStyles are ProConcrete tasks described in chapters further through this training manual. Now click the OK button, and then move onto the next empty class. Note: When you choose to assign parts to Part Families will depend on the size and complexity of your 3D model.

Concrete Floor Slabs
Concrete slabs can be created in ProConcrete 3D through the use of the “Create Slab” button, located on the ProConcrete 3D main toolbar and the ProConcrete 3D Slabs toolbar. When clicking this button you are presented with the “ProConcrete 3D Slab” dialog box. This dialog box allows you to create single thickness slabs (suspended or on grade) that are rectangular in shape, or multi-sided. You can pick points to input the slab shape, or you can pick a pre-drawn polyline to define the slab.
The DIMENSIONS area of the dialog box is used for adding the Thickness, Length and Width values. Offset values can also be applied from here. INSERTION PLANE and INSERT EDGE are used to control slab placement. The OPTIONS area is used to define Label, Material used, applicable Layer and Display Classes etc. Choices are available via several dropdown lists.
This button is used to define the shape of the slab by picking existing points on your 3D model.

Exercise 07-1 Adding New Slabs In this exercise, we will add some in-situ slabs to the front and rear areas of our 3D building model. At Level 0 the slabs will be on ground. At Levels 1 and 2 they will be suspended slabs.
1. Close your previously created drawing. Now find and open the supplied AutoCAD drawing called 7092Model1c.dwg. Use the AutoCAD SAVEAS command to save this drawing as 7092Model1.dwg to your C:\Cad Projects\7092\Model folder. This will replace your previously created drawing with a new one of the same name.
2.
The model on this drawing looks similar to the earlier model, except for the addition of some yellow coloured AutoCAD polylines that have been added at each floor level. These polylines will be used to create new floor slabs at all levels of your existing 3D building model. Some of these floor slabs will be created as insitu slabs. Others will be created as precast panel floor slabs.
3. Zoom to the area between Grid A and Grid B. Notice that a yellow polyline has already been drawn for you at Levels 0, 1 and 2. These existing polylines will be used to create new in-situ floor slabs in these areas. Note that each polyline is flush with the top of slabs that have previously been created between Grids B and D.
The thick black polyline shown on the diagram here is indicative of the yellow polylines that you will find on your existing model, at Levels 0, 1and 2. The polylines have been drawn f lush with the top of the adjoining slabs between Grids B and D.
4. Zoom to the Level 2 area between Grids A and B, (remain in Isometric Overview 1 mode) then click the “Create Slab” button , located on the ProConcrete 3D main toolbar or the ProConcrete 3D Slabs toolbar. You are now presented with the “ProConcrete 3D Slab” dialog box. We will create a slab that is 150mm thick, this will match the thickness of the slabs already drawn at Level 2 (between Grids B and C) of your 3D building model. The values within the dialog box need to be as per those shown in the diagram on the next page (Length and width dimensions will not affect our resulting slab, as we will pick the already drawn yellow polyline to define the extent of the slab).
88 Copyright © 2009 Bentley Systems, Incorporated
Mar-10
Objectives
Select Object ECS and TOP Insertion Edge for new slabs to match the level of the existing slabs.
Ensure that you use the dropdown lists at the right hand side to assign the new slab to the correct Part Family, Display Class, and Area Class value.
5. From the dialog box shown above, click the “Insert a Slab by a Speci fied Polyline” button. Follow the prompts at the AutoCAD command line to pick the previously created yellow polyline at Level 2. The slab is now created, and the dialog box reappears. Finish the command and the dialog box with the OK button at bottom left of the dialog box.
6. Repeat steps 4 and 5, but this time for the previously created polyline at Level 1, however under the OPTIONS area of the dialog box you will need to change the Display Class value to Level 1 Slab.
7. Repeat steps 5 and 6, but this time for the previously created polyline at Level 0, however under the OPTIONS area of the dialog box you will need to change the Display Class value to Level 0 Slab. Make this slab 200mm thick, rather than 150.
8. Now repeat steps 4 to 7, but this time for the area between Grids D and E. You may want to view your model from the Isometric Overview 4 direction before modeling the slabs. You will again find already drawn yellow polylines at each of the levels in this area. When completed, return to your overall isometric view, and save your drawing to hard disk.

Precast Concrete Floor Slabs
Precast Concrete Floor Slabs
Precast concrete f loor slabs can be created in ProConcrete 3D by use of the “Create Precast or Composite Slab” button. This command enables you to create both precast slabs, and composite slabs, with or without topping slabs. You can create these slabs by either of two methods. The “Create Precast/Composite Slab by Polyline” method enables you to create the precast floor panels with topping slab by picking at least 2 already drawn polylines. These polylines should represent the extent of the topping slab, and the extent of the precast f loor panels. The “Create Precast/Composite Slab by Beams” method allows you to create the precast floor panels with topping slab by selecting the already drawn beams that form the perimeter of the slab area. Buttons are located on the dialog box that allow you to use the best method available. The “Create Precast or Composite Slab” button is located on the ProConcrete 3D main toolbar, and on the ProConcrete 3D Slabs toolbar. The command and button will provide you with the “ProConcrete 3D Slab Tools” dialog box shown below.

Precast Concrete Floor Slabs
Exercise: Adding a Precast Concrete Floor Slab In this exercise, we will add a precast concrete floor slab to the arced area of our 3D building model. This slab will only be at Level 2.
1. Click the Isometric Overview 1 button
to enable the overall isometric view of your model . Remember the Isometric Overview 1 button presents you with a zoomed extents view. Ensure you are in 2D wireframe mode. Now zoom to the Level 2, arced area of your building. (This is the area of your building model, where the angled beams sit atop the circular columns).
2. You will find two already closed yellow AutoCAD POLYLINES at Level 2 that will be used to form the precast concrete floor panel area. The polylines are shown in the diagrams below.
This hatched area indicates the extent of Polyline No.1. It aligns with the outside of the angled beams.
Mar-10
95 Copyright Š 2009 Bentley Systems, Incorporated
Precast Concrete Floor Slabs
3. Polyline No. 1 will be used by the Create Precast or Composite Slab command to define the outside edge of the Topping Slab area. Polyline No. 2 will be used to define the outside edge of the Precast Concrete Floor Panel area.
4. Before placing the precast floor panels and topping slab, check the modeled height of the 4 angled beams in this area, and the beam along Gridline C. The modeled height of these beams should be 325mm. The design height is 500mm, but a setdown of 175mm was applied at the time of creation. You can refer back to chapter 4 to see what was done here.
5.
Now click the “Precast/Composite Slab” button, located on the ProConcrete 3D main toolbar or the ProConcrete 3D Slabs toolbar. You are presented with the “ProConcrete 3D Slab Tools” dialog box. Fill out the values within the box as shown below and on the next page.
Note: In this particular case, we are not using steel decking as a part of our floor slab, so the current settings in this tab of the dialog box can be ignored. You should not use this assignment tab unti l the elements have been created by use of the “Create Precast Slab by Polys” button. The dialog box will re-appear after the elements have been created.

Precast Concrete Floor Slabs
6. Now click the “Create Precast Slab by Poly” button
located on the Dimensions tab of the “ProConcrete 3D Slab Tools” dialog box shown above. You are asked at the AutoCAD command ine to “Pick Polyline of Slab/Topping Edge”. Pick Polyline No. 1 shown on the previous page. You are now asked to “Pick a line to Define the Main Direction or Enter for Points”. Pick a polyline edge that runs parallel with Grid 3. This will indicate the direction that the precast panels will run in. Pick Polyline No. 2 created in Steps 2 and 3. You are now asked to “Pick a Polyline of Precast Element Edge, or Enter Offset Value”. Select Polyline No. 2 shown on the previous page. You are then asked at the command line to “Pick the Insert Point”, osnap to the inside junction point of the angled beams where they meet at Gridl ine 3 (you could maybe osnap to the end of the yel low polyline line drawn here). The precast floor panels with topping slab are placed, and you are now presented with the “Precast Slab Tool” dialog box again. You can now set the assignments for the Topping Element and the Precast Elements as shown in the diagram above.
7. Finish the dialog box with the OK button. (Note: If you see that the precast panels placed are not aligned to Gridline 3, but placed at a strange angle, then you may need to CANCEL the command with the cancel button at bottom left of the dialog, and then retry by picking the Polylines at different points. I have picked points on the polylines that are near the top of the circular column at the far right of the beam at Gridline C).
8. The precast concrete floor panels with topping slab are all placed at the same time with the one command used in Step 6. However if you examine your model closely you will see that the panels clash with the beam at Gridline 3. We will need to cut the panels here so that they also sit on each edge of this particular beam with 50mm seating, as per the seating at the angled beams.

9. Click the Blue system line that has been placed with the precast concrete panels. This system line controls the extent and design of the panel slab system. Now right click, and from the context sensitive menu, choose PS3D Properties. The “Precast Slab Tool” dialog box that was used to create the panels and topping slab returns. The current values are displayed in the dialog box. Go to the BORDER LINES tab of the dialog box. Ensure that the CUT WIDTH is set to 300mm (the beam width is 400, so 300 will provide a 50mm seating each side of the beam). Also ensure that CUT TOPPING is unticked (we do not want to break the topping at this point, only the precast floor panels).
10.
Now click the “Add a Cut Line” button located on the BORDER LINES tab. You are asked at the AutoCAD command line to “Pick a Line to Define a Border”. Pick the white construction line that runs down the centre of the Gridline C beam. The panels are now cut at the beam. Finish the command and the dialog box with the OK button. Save to disk
11.
SHADE your model to inspect for clashes. You may want to delete some of your unwanted construction lines. Remember that until now, all of these have been created on Layer 0.
12.
ORBIT around your model to inspect for clashes. Save your drawing to hard disk once more. Your overall 3D model should now look similar to that shown in the diagram below.

The penetration is created within that single panel, and the dialog box re-appears. Click the Create Window button again, and now pick the last of the 5 panels along the long wall line. The penetration is created, and the dialog box reappears. Click the OK button to finish the command. The penetrations should look similar to those shown in the diagram on the next page.
5. Zoom to the in-situ concrete walls drawn in Exercise 08-1, and we will now add some penetrations to these walls. As there is no system line that controls them, we will need to use some Prosteel / Proconcrete modification commands to create the penetrations.
6. Click the Element Modification 1 button
(located on the ProSteel 3D Edit toolbar), and when the Element Modification dialog box appears, click the WALLS tab to make it current.
7. Set the values within the “Element Modification” dialog box as shown below: Note: Doors and Windows placed using this feature can be moved or changed in size. Invoke the PROPERTIES of the wall that the openings belong to, and editing of the openings can be done from the resultant Door/Window tab. Highlight the wanted opening if there are several via the arrow buttons at the bottom of the tab. Grips can be used once you have selected the appropriate opening.

8. Now click the “Enables to Add a Window to a Wall” button
, located on this tab. You are asked at the AutoCAD command line to “Pick the Wall in which the Window should be Inserted, near to the Reference Point”. Pick the outer small wal l segments of the 3 segments that were previously created. Pick the wall along a top edge near where it meets the existing column. You are now asked at the AutoCAD command l ine to “Pick insertion Point for Wall Opening”. Osnap to the midpoint along the top inside edge of this wall (not the outside). The window opening is placed and the dialog box re-appears. One side of the opening is located directly at the midpoint of the wall (the location that you osnaped to).
9. Repeat Step 9 two more times to add windows to each of the remaining in-situ wall segments. When asked to locate the opening, OSNAP to the inside midpoint of wall in each case. The dialog box will re-appear after adding each of the window penetrations.
10. Now click the “Enables to Add a Door to a Wall” button
, located on this WALLS tab of the Element Modif ication dialog box. You are asked at the AutoCAD command line to “Pick the Wall in which the Window should be Inserted, near to the Reference Point”. Pick the long wall segment, but nearest the left end of this wall (nearest the outside rear corner). At the AutoCAD command line you are asked to “Pick Insertion Point for Wall Opening, or Distance”. As you slide your cursor along the wall, you will see a yellow marker down at the bottom of the wall. This is indicative of where you want to place the opening. Manually slide your cursor about 1 metre to the right of the wall corner, then left click. (be careful not to accidentally OSNAP to any drawn object). The door penetration is formed and the dialog box returns. Click the “Enables to Add a Door to a Wall” button again. This time, pick the long wall nearest the right hand end, and when asked to “Pick Insertion Point for Wall Opening, or Distance”, answer at the keyboard with the D for distance option. You are now asked at the command line to “Set the Distance to the Wall Corner”. Type 1500 at the command line, and enter. The door opening is formed, and the dialog box re-appears. Finish the command and the dialog box with the OK button. The penetrations should look similar to those shown in the diagram below.

More Concrete Modeling
Overview In this chapter, you add some additional floor slabs and some strip footing under ground floor slab edges.
Objectives In this chapter, you will:
Mar-10
Ensure all current concrete objects are currently assigned to classes. Add some new ground floor slabs. Add some additional precast concrete floor slabs. This chapter represents fundamental concepts you need to know about the modelling process in ProConcrete 3D. The tutorial is not necessarily best practice of structural concrete design but focuses on using various ProConcrete 3D commands.
117 Copyright © 2009 Bentley Systems, Incorporated
Objectives
Exercise 09-1 Adding New Ground Floor Slabs In this exercise, we will add some new ground floor slabs to the areas drawn behind Gridline 1. These areas are enclosed by the in-situ walls and the precast concrete panel walls drawn in the previous chapter.
1. Open your previously created model if not already open. It should be drawing number 7092Model1, in the C:\Cad Projects\7092\Model folder. Now click the Isometric Overview 5 button to enable the overall isometric view of your model, from the rear left side of the building model. Remember the Isometric Overview 5 button presents you with a wireframe zoomed extents view. 2. This is now a good time to tidy up some of your already completed concrete model. Click the Display Classes button to begin assigning objects that do not currently have a display class assignment, to a relevant class. Use the classes created in Chapter 6. You may need to create some new wall classes. (Hint: You can confirm which objects are not yet assigned to a class, by turning OFF al l previously created classes. Those objects that are left visible on the screen, are objects that are as yet unassigned). Also click the Area Class button to begin assigning all currently non-assigned objects. Again use the classes created in Chapter 6. You may also need to add a new Area Class for the new walled area. Now turn off all Classes that have objects assigned, from Level 1 and above. This will make it easier to now draw new objects down at the lower levels of our model. We will not be hindered by the congestion of all of the objects already drawn at the upper levels of our model. 3. Now is also a good time to erase any unwanted construction lines, or place them on a unique Display Class. If you know a construction line will not be needed for future use, then erase it so that your model file size is kept to a minimum, and so that you can continue modeling with less congestion. 4. Zoom to the area behind Gridline 1, and inside the in-situ wal ls drawn in the previous chapter. Draw the following closed polyline as indicated by the extent of the hatched area shown on the diagram below. Ensure that the polyline is drawn in an anti-clockwise direction, and at a level that is 200 below Ground Level (the top of the strip footings, underside of the walls). Hint: It is best to remain in an isometric viewpoint when creating these polylines.

Objectives
5. Now draw another closed polyline as indicated by the extent of the hatched area shown on the diagram below. The area concerned is behind Gridline 1, and inside the precast concrete walled area drawn in the previous chapter. Ensure that the polyline is drawn in an anti-clockwise direction, and at a level that is 200 below Ground Level (the top of the strip footings, underside of the walls). Hint: It is best to remain in an isometric viewpoint when creating these polylines. Draw the polyline such that it extends to the outer corners of the doorways, but is otherwise on the inside edges of the walls.
Draw the polyline such that it follows the underside edges of any slabs already drawn between grids 1 and 2.
6. Remain viewing your model from an isometric vantage point, preferably Isometric Overview 5, zoom to the first of the 2 polylines just created, and then click the “Create Slab” button . You will then see the “ProConcrete 3D Slab” dialog box. Fill in the values as shown below.
Mar-10

Objectives
7. Now click the “Insert a Slab by Selected Polyline” button
on the ProConcrete 3D Slab dialog box, to begin placing the slab. At the AutoCAD command line you are asked to SPECIFY A POLYLINE OR A CIRCLE OR AN ARC. Pick the first of the polylines drawn at Step 4. The slab is drawn and the dialog box returns. Finish the dialog box and the command with the OK button. 8. Repeat Step 7, but this time for the second of the polylines drawn at Step 5 of this exercise. When completed you should end up with 2 new slabs inside the walled areas at the back of your building model. The top of these slabsaligns with the top of the existing slabs modeled between gridlines 1 and 2. These 2 new slabs could be unioned to the existing slabs with one of the ProSteel 3D Boolean commands, but for the time being we will leave these as separate slabs. The separate slabs could allow for different pours of concrete slabs. Turn ON all classes that were previously turned OFF.
9.
Finally, add 4 separate steel channels to the outside of all of the concrete beams currently drawn at Level 1, Gridline 1. These channels will be used to support some additional precast concrete floors over the walled area created in the last chapter. The top of the top channel flanges should be 150 below Level 1. The web of the 250PFC’s should be flush against the outside face of the concrete beams at gridline 1. Place the 250PFC’s using the ProSteel 3D Shape dialog box.

10. Leave OFF all Display Classes and Area Classes that are currently turned off. Save your drawing to hard disk again.
Setting your UCS and your VIEW to Objects Often when you are model ing either concrete structures with ProConcrete 3D, or steel structures with ProSteel 3D, you will want to align your current UCS to one of the faces of an existing object, or you will want to view that object as though it were al igned to your screen. There are several tools with both ProConcrete 3D and ProSteel3D that allow us to deal with these situations. To set your UCS current to an object, use one of the following icon commands:
“Object UCS Centered” and “Object UCS at Point” commands allow for orientation of a new UCS aligned to the concrete object or portion of the Concrete Shape. “Face UCS Centred” and “Face UCS at Point” commands align the users UCS with any Bodyface by selecting an edge.
To set your current view aligned to the object, use one of the following icon commands:
Mar-10
121 Copyright © 2009 Bentley Systems, Incorporated
Setting your UCS and your VIEW to Objects
“Object View Centered” and “Object View at Point” commands allow for the orientation of your current view to be aligned with the concrete object or portion of the Concrete Shape. “Faceview Centred” and “Faceview at Point” commands align the users view with any Bodyface by selecting an edge. The Object UCS icons, and Object View icons shown above, can be found on the “ProSteel 3D Viewtools” toolbar, or on the “Object UCS” and “Object View” toolbars. Alternatively, all four commands can be found under the ProSteel 3D – Zoom/Views pulldown menu.
When using the above mentioned commands you are presented with a 6 pointed, 6 colored compass type screen icon. (In some case it will be a 2 pointed, 2 colored compass type screen icon). Left click the endpoint, or colored end, which is equal to the face of the object or portion of the shape desired to work with.

Exercise 09-2 Adding New Precast Concrete Floor Slabs In this exercise, we will add some suspended precast concrete floor slabs with topping to the areas drawn behind Gridline 1. These areas are enclosed by the in-situ walls and the precast concrete panel walls drawn in the previous chapter. 1. Remain viewing your model from the last used isometric vantage point in the previous exercise. (Isometric Overview 5)
2. We will now align our UCS to the top of the precast concrete walls. Click the “Object UCS at Point” icon , located on the ProSteel 3D Object UCS toolbar. (You can also f ind this within a flyout menu on the ProSteel 3D Viewtools toolbar). You are asked at the AutoCAD command line to SELECT ELEMENT TO SET VIEW. Pick the top of one of the precast panels drawn in the wall long direction (one of the panels drawn parallel to Gridl ine 1). You will now see the six headed, six coloured screen icon at this point, and you are asked at the command line to PICK DESIRED AXIS. Click on the topmost cone of the icon (it is probably coloured magenta, your cursor will temporarily become a cone sitting atop this cone). Your current UCS is now set to match the top of the panel.
3. Now draw 2 closed polylines at this level. (This is at the level equal to the top of the walls drawn in the previous chapter. 200mm below Level 1.) All of the closed polylines should be drawn in an anti-clockwise direction. The first of the polylines will indicate the extent of the 1200 wide x 75 thick precast floor panels to be placed over. The second polyline will indicate the extent of the 75mm topping thickness above. The extent of the polylines is according to the hatched areas indicated in the diagrams shown below. The polylines will be at a level equal to the underside of the precast panels.
The first polyline indicates the extent of the wanted precast floor panels.

Setting your UCS and your VIEW to Objects
4. Adjust the first polyline drawn such that it overlaps the top of the walls that are parallel to Gridline 1 by 50mm. This will allow the precast floor panels to have a 50mm seating to top of walls. Do not adjust the polyline along the short walls. Use AutoCAD GRIP editing techniques to adjust the polylines. See the diagram at Step 5.
5. Adjust the first and second polylines such that a gap is created between the polylines and the beams and columns already created along Gridline 1. This will allow for an expansion gap to be generated between your new precast floor panel area, and your existing concrete structure. Use AutoCAD GRIP editing techniques to adjust the polylines such that the gap will be 20mm. See the diagram below. Also draw a construction between the midpoints of the long sides of the polylines, as shown in the diagram below. This line is down the central top face of the in-situ wall at Gridline C.
6. Now click the “Precast/Composite Slab” button
to begin creating the precast panel f looring area. This button can be found on the ProConcrete 3D Main Toolbar, and the Slab toolbar. The “ProConcrete 3D Slab Tools” dialog box now appears. Modify the values in the dialog box according to the diagrams shown on the next page.

7. On the DIMENSIONS tab, ensure that you set the topping thickness to 75. On the SHAPES tab, ensure that you size the panels to 1200 width x 75 thickness. No Cut Lines or Openings will be created in this case by the use of the BORDER LINES tab.
8. Now click the “Create Precast Slab by Poly” button
, located on the bottom left on the Dimensions tab. You are asked at the AutoCAD command line to PICK A POLYLINE TO DEFINE OUTER CONTOUR. By this it is meant that you pick the polyline that indicates the extent of the concrete topping that forms part of this slab area. Pick the second polyline that was created at Step 3. You are next asked at the AutoCAD command line to PICK A POLYLINE TO DEFINE INNER CONTOUR. By this is meant that you pick the polyline that indicates the extent of the precast concrete floor panels that form part of this slab area, and that will be placed with this command. Pick the first polyline that was created at Step 3. You are now asked at the command line to PICK A LINE TO DEFINE THE MAIN DIRECTION. Pick the construction line drawn between midpoint of opposite polyline segments (at Step 5 -See the diagram above). You are now asked to PICK INSERT POINT. It is meant here that you indicate the setout point for the precast floor panels. OSNAP to the midpoint of the long outermost straight line segment of the inner polyline (See the diagram above).
9. Finish the command with the OK button on the dialog box. Your precast flooring panel area should look like the diagram shown on the next page, when unshaded.
Note that the panels run in the short direction, from the PFC channels at the beams along Gridline 1, across to the top of the in-situ and precast concrete walls adjacent. A hidden line removal view of your precast flooring panel area should look like the diagram shown below. Notice that there is a 20mm gap from the topping slab, across to the slab beyond Gridline 1.

Adding Rebar to Concrete Footing Pads
Adding Rebar to Concrete Footing Pads
Rebar cages can be added automatically to previously created Footing Pads by the use of the “Pad Footing Rebar” command . This command allows you to place and size patterns of Bottom bars, Top bars and Side bars. Top and side patterns can be ignored if not needed. The bar lengths are determined automatically by the pad being used, the previously created pad rebar, and the values placed in the dialog box cells. There is no need to manually input the length of pad bars. The REINFORCEMENT tab shown below is used for determining the rebar components. That is the size of bars, spacing and cover.
If “Top Steel” is not required, then do not tick this box. The area to the right of this tick box is greyed out, and input from the user cannot be accepted. If the Above_Below cell is ticked, then the layers of bars will collide, but if unticked, they will pass one above the other.
Available cells and dropdown lists allow you to input bar spacings, bar diameters, and concrete cover to reinforcing.
The STARTER tab, as shown, allows you to include and define starter bars with your pad. Starter bars can only be placed if there is an already placed rebar cage in the column that you are attaching the pad to. End conditions can be edited for the starters via the “Edit Current End Conditions” button.

The STYLE tab allows you to save a style of Footing Pad Reinforcement, to be used in other areas of your model, or on other ProConcrete 3D projects. The Styles feature is used in a similar fashion to the template button. However when using a style, numbers of bars are determined automatically according to the size of the footing pad being used.
The OPTIONS tab allows you to choose whether bars are displayed in a line mode or a cylindrical mode. Hint: The cylindrical mode will allow you to check for clashes.
NOTE: Always ensure that you finish placing Footing Pad rebar by clicking the OK button at bottom left of the dialog box.

command will give you access to a right click context sensitive menu that allows you to zoom and pan while orbiting, and enables you to turn shading on and off also while orbiting. 4. We will now save the settings from this Footing Pad to be used for other pads. We will use the STYLE tab from the ProConcrete 3D Pad Footing Reinforcement dialog box to do this. To gain access to the dialog box and the values used to create it, left click the Rebar Cage (the one created in Step 2) once to highlight it, then right click to achieve a context sensitive right click menu. Choose PS3D Properties from the menu, and you will now see the “ProConcrete 3D Pad Footing Reinforcement” dialog box containing the rebar values. Go to the STYLE tab of the dialog box.
5. From the STYLE tab, click the “Create New Style by Current settings” button
, to save the style of footing pad rebar for future use. You will now be presented with a dialog box that enables you to save the style with a given name, and to a chosen folder. By default, the folder will be relevant to Footing Pads. It will be the “PadFootingRebarStyle” subfolder. (Full path is C:\Program Files\Bentley\ProSteel 3D\V8i\AutoCAD 2008\Localised\English\Styles or similar). Save the Rebar Cage settings with the STYLE name Training-Pad1.usy. Note that you should not need to type the extension .usy as this is the default file type for ProConcrete 3D Styles. You will need to click the SAVE button on the dialog box. Back at the STYLES tab, you will now see your style displayed in a list of available styles. Click the OK button to finish the command & close the ProConcrete 3D Pad Footing Reinforcement dialog box.
6. Now click the Isometric Overview 1 button
, and then zoom to footing pad at the base of the column drawn at the Grid 2, C intersection. This pad is larger than the one previously used. It is 1200 x 1200 x 300 deep.
7. Click the “Pad Footing Rebar” button
, and when asked at the AutoCAD command line to “Select a Footing Pad”, click the pad at the Grid 2, C intersection. A reinforcement cage is automatically added to the pad, and the “ProConcrete 3D Pad Footing Reinforcement” dialog box appears. Go to the STYLE tab of this dialog box.
8. Highlight the listing “Training-Pad1” within the STYLES tab list of styles, and then click the “Apply Selected Style to Current Drawing” button. Finish the command and dialog box with the OK button . You will notice that the rebar added to this pad, is similar to the rebar added at the previous pad, but that there are more bars in each direction. This is because of the larger size of the pad. The bar diameters and bends are as per the previous pad rebar cage. 9. Repeat steps 7 and 8 to add more rebar cages to the pads at Grid Intersections 2A, 1E and 2E. Apply the “Training-Pad1” style. Also add rebar cages to the pads at the bottom of the 3 cylindrical columns around the Zone 4 arced area of the building model. Note that all Rebar placed with this command is automatically placed on the ProConcrete Layer “PS_Rebar”. The cages are not automatically assigned Display Classes or Area Classes. Save your model to hard disk once more. Mar-10

Adding Rebar to Concrete Columns
Adding Rebar to Concrete Columns Rebar cages can be added automatically to previously created Concrete Columns by the use of the “Beam Column Rebar” command . This command allows you to place and size all bars needed for a Column Rebar Cage or a Beam Rebar Cage. Top bars, bottom bars, side bars and stirrups can all be designed by the user. The bar lengths are determined automatically by the length of the column or beam being used, and the values placed in the dialog box cells. There is no need to manually input the length of column / beam bars. Bar ends can also be designed with or without projections, and bends if required. The dialog box used for adding rebar to ProConcrete 3D Column and Beam Shapes is called the “ProConcrete 3D Single-Cage Reinforcement” dialog. It has many tabs, they are documented below. The REBARS tab shown below allows you to design the vertical rebars for columns, and the horizontal (longitudinal) rebars for beams. You decide how many bars for each zone (face of column or beam), you choose a size (dia) for these bars, and also you choose a concrete cover to these bars. A preview diagram to the right side of the dialog box shows you your chosen design as you are completing it.
The END CONDITIONS tab (shown on the next page) enables you to create bar end projections if needed (with or without bends), hooks or cranks. End conditions can be chosen for each end of each of the bars to the zones (column / beam faces) that have been used in the REBARS tab. Dropdown lists are used to access the list of standard end conditions. Offset distances for each of the end conditions can be set from this tab, and if needed, standard end conditions can be overwritten to produce almost any end condition imaginable. For instance, a bar end can be bent to any angle, left, right, up or down, forward or away from the column or beam. And bend radii can also be specified. End Properties for each zone of bars can be edited by clicking the appropriate “Edit the Current End Condition Values” button on the END CONDITIONS tab. 134 Copyright © 2009 Bentley Systems, Incorporated

Typical stirrup spacings can achieved by inserting a wanted value here.
Hinge Zones can be achieved by ticking Start or End Zones, or both. Stirrup spacing, and length of the hinge zones can be controlled from here.
The STIRRUP tab shown below is used to design stirrup sizes and spacings. Hinge zones that have stirrups spaced at closer centres can also be achieved from here. You can achieve more than one hinge zone per column or beam end. A preview diagram to the right side of the dialog box, shows you your chosen design as you are completing it.
The STYLES tab allows you to save dialog box settings and retrieve them again. The STYLE tab allows you to save a style of Column or Beam Reinforcement, to be used in other areas of your model, or on other ProConcrete 3D projects. The Styles feature is used in a similar fashion to the template button. However when using a style, numbers of bars are determined automatically according to the size of the column or beam being used.
The COLLISION tab allows you to control how laps and joggles should automatically re-act when collisions between rebar cage elements are detected.

1. Open your previously created model if not already open. It should be drawing number 7092Model1, in the C:\Cad Projects\7092\Model folder. Now click the Isometric Overview 1 button , and zoom to the Column at the Grid 1,A intersection. This column is 2 storeys high (500 wide x 500 long x 6200 high).
2. Click the “Beam/Column Rebar” button
. It is located on the ProConcrete 3D Main Toolbar and the Beam/Column toolbar. You are asked at the AutoCAD command line to “Select Objects”. Click the column at the Grid 1,A intersection, and then right click to avoid choosing more columns. A reinforcement cage is automatically added to the column, and the “ProConcrete 3D Single-Cage Reinforcement” dialog box appears. Notice that the end conditions shown at the top of the column are coloured red, the end conditions at the bottom of the column are coloured green. Changing values in the dialog box will change the appearance of the cage just placed. Fill out the values in the dialog box as shown below. As you use the cells and drop-down lists in the dialog box, so the column on the 3D model will change to reflect your column cage design.
(Note that we will add end conditions that include bends at the bottom of the column cage, we will leave end projections at the top of the column that are straight. These can be left as projections for a future addition to the building model, or we can edit the projections at a later stage so that bends are included).

Adding Rebar to Concrete Columns
Important Note: If you notice when completing the column cage, that the rebar cage has been placed upside down (bent bars at top, and projection bars at bottom), then this is an indication that your concrete column has been drawn upside down. You may not have intentionally drawn your column upside down. The upside down placement may have occurred automatically because you attached the column to a line (some polyline segments will run top to bottom, rather than bottom to top). You can solve this upside down problem by either of two methods, as indicated here. Method 1. – On the REBARS tab of the ProConcrete 3D Single Cage reinforcement dialog box, use the Projection end conditions in the 4 START end condition dropdown lists (cell names are coloured green). Use the Bend end conditions in the 4 END end condition dropdown lists (cel l names are coloured red). Method 2. – Erase the column rebar cage, then double cl ick the offending column. You will see the ProConcrete 3D ConcreteShape Properties dialog box. This shows you the properties of the column. On the POSITION tab of this dialog box, click the “Turn the Current ConcreteShape” button located in the bottom left of the dialog box. This will turn the column up the other way. There may appear to be no visual difference when completing this task. However, if the concrete footing pad move to the top of the column, you may need to erase the pad, and place a new one. Or you could copy a concrete pad from another part of your 3D model. Add the rebar cage after turning the column.
4. We will now save the settings from this Column to be used for other columns. We will use the STYLE tab from the ProConcrete 3D Single-Cage Reinforcement dialog box to do this. To gain access to the dialog box and the values used to create it, click the Column Cage (the one created in Step 2) once to highlight it, then right click to achieve a context sensitive right click menu. Choose PS3D Properties from the menu, and you will now see the “ProConcrete 3D Single-Cage Reinforcement” dialog box containing the rebar values. Go to the STYLE tab of the dialog box.
5. From the STYLE tab, click the “Create New Style by Current settings” button
, to save the style of footing pad rebar for future use. You will now be presented with a dialog box that enables you to save the style with a given name, and to a chosen folder. By default, the folder will be relevant to columns. It will be the “BeamColumnCageStyles” subfolder (Ful l path is C:\Program Files\Bentley\ProSteel 3D\V8i\AutoCAD 2008\Localised\English\Styles or similar). Save the Rebar Cage settings with the STYLE name Training-Col1.usy. You will need to click the SAVE button on the dialog box . Back at the STYLES tab, you will now see your style displayed in a list of available styles. Click the OK button to finish the command and close the ProConcrete 3D Single-Cage Reinforcement dialog box.
6. Now click the Isometric Overview 1 button
, and then zoom to lowest column at the Grid 2,C intersection. (The one at Level 0 only). This column is larger than the one previously used. It is 600 x 600 but is only 2600 high.

7. Click the “Beam/Column Rebar” button
, and when asked at the AutoCAD command l ine to “Select an Object”, click the lowest column at the Grid 2,C intersection. A reinforcement cage is automatically added to the column, and the “ProConcrete 3D Single-Cage Reinforcement” dialog box appears. Go to the STYLE tab of this dialog box.
8. Highlight the listing “Training-Col1” within the STYLES tab list of styles, and then click the “Apply Selected Style to Current Drawing” button. Finish the command and dialog box with the OK button . You will notice that the rebar added to this column, is similar to the rebar added at the previous column, but that there are fewer stirrups. This is because of the shorter height of the column. The bar diameters and end conditions are as per the previous column rebar cage. The top end conditions of this column can be altered at a later stage to allow for the column over at Level 1. They could be changed to CRANKED ends to allow for lapping with column rebars above.
9. Repeat steps 7 and 8 to add more rebar cages to the columns at Grid Intersections 2A, 1E and 2E. Apply the “Training-Col1” style.
Note that all Rebar placed with this command is automatically placed on the ProConcrete Layer “PS_Rebar”. The cages are not automatically assigned Display Classes or Area Classes. Save your model to hard disk once more.

Adding Rebar to Concrete Columns
Exercise 10-3 Reinforcing the Circular Columns In this exercise, we will add some Column Reinforcement Cages to all of the currently created circular columns. We will also save the cages with a Style for future use.
1. Click the Isometric Overview 1 button
(available on the ProSteel 3D Viewtools toolbar) to see an overall view of your model. Of course clicking any ProSteel 3D Isometric Overview button will turn off any shading that is currently on, returning you to a zoomed extent wireframe view. Now zoom to the circular column at the right end of Gridline C. Note that this circular column is 2 storeys high. No beams meet it at Level 1.
2. Click the “Beam/Column Rebar” button
. You are asked at the AutoCAD command line to “Select Objects”. Click the circular column at the end of Gridline C and then right click to avoid choosing more columns. A reinforcement cage is automatically added to the column, and the “ProConcrete 3D Single-Cage Reinforcement” dialog box appears. The cage has circular stirrups because ProConcrete 3D software recognizes the column as a circular one, and produces a cage shape to match. However the number of vertical bars, and stirrup spacings are not correct. Fill out the values in the dialog box as shown in Step 3 to adjust the cage shape. As you use the cells and drop-down lists in the dialog box, so the column on the 3D model will change to reflect your column cage design. Important Note: If your column cages appear to be upside down, it is because your columns were placed upside down. This has more than likely occurred if your construction lines used to place the columns were drawn top to bottom, rather than bottom to top. You could try and fix this problem by using the “Turns the Current ConcreteShape” button located on the “ProConcrete 3D ConcreteShape Properties” dialog box. However when you do this the pads will move to the top end of the column. This is because they are intelligently linked to the end of the column. We do not want them to follow. You may need to delete the pads, and pad cages, then replace them again after you have turned the column. You may need to turn each of the circular columns.
This image needs to be replaced, but the current one does not have the turn shape icon. I have questioned this with Nabil.

Rebar Cages – Beams
Overview In this chapter, you learn about adding reinforcing bar cages to simply supported concrete beams.
Objectives In this chapter, you will:
Get an overview of the beam reinforcement command.

Adding Rebar to Concrete Beams
Reinforcing bar cages can be added automatically to previously created Concrete Columns by the use of the “Beam/Column Rebar” command. The command allows you to place and size all bars needed for a Column Rebar Cage or a Beam Rebar Cage. Top bars, bottom bars, side bars and stirrups can all be designed by the user. The bar lengths are determined automatically by the length of the column or beam being used, and the values placed in the dialog box cel ls. There is no need to manually input the length of column / beam bars. Bar ends can also be designed with or without projections, and bends if required. The dialog box used for adding rebar to ProConcrete 3D Column and Beam Shapes is called the “ProConcrete 3D Single-Cage Reinforcement” dialog. It has many tabs, they are documented below. The REBARS tab shown below allows you to design the vertical rebars for columns, and the horizontal (longitudinal) rebars for beams. You decide how many bars for each zone (face of column or beam), you choose a size (dia) for these bars, and also you choose a concrete cover to these bars. A preview diagram to the right side of the dialog box shows you your chosen design as you are completing it.
The END CONDITIONS tab shown on the next page enables you create bar end projections i f needed, with or without bends, hooks or cranks. End conditions can be chosen for each end of each of the bars to the zones (column / beam faces) that have been used in the REBARS tab. Dropdown lists are used to access the list of standard end conditions. Offset distances for each of the end conditions can be set from this tab, and if needed, standard end conditions can be overwritten to produce almost any end condition imaginable. For 152 Copyright © 2009 Bentley Systems, Incorporated

instance, a bar end can be bent to any angle, left, right, up or down, forward or away from the column or beam. And bend radii can also be specified.
End Properties for each zone of bars can be edited by clicking the appropriate “Edit the Current End Condition Values” button on the END CONDITIONS tab. This gives you access to the wanted “ProConcrete 3D Rebar End Properties” dialog box for the chosen end condition.
Use the dropdown lists to access bends, hooks, cranks and projections as your wanted end condition.
Click any of these buttons to access the “ProConcrete 3D Rebar End Properties” dialog box for the chosen bar end.
The STIRRUP tab shown below is used to design stirrup sizes and spacings. Hinge zones that have stirrups spaced at closer centres can also be achieved from here. You can achieve more than one hinge zone per column or beam end. A preview diagram to the right side of the dialog box, shows you your chosen design as you are completing it.

Objectives
Typical stirrup spacings can be achieved by inserting a wanted value here.
Hinge Zones can be achieved by ticking Start or End Zones, or both. Stirrup spacing, and length of the hinge zones can be controlled from here.
The STYLES tab allows you to save dialog box settings and retrieve them again. The STYLE tab allows you to save a style of Column or Beam Reinforcement, to be used in other areas of your model, or on other ProConcrete 3D projects. The Styles feature is used in a similar fashion to the template button. However when using a style, numbers of bars are determined automatically according to the size of the column or being used.
The Collision tab allows you to control how laps and joggles should automatically re-act when collisions between rebar cage elements are detected.

Exercise 11-1 Adding Beam Reinforcement In this exercise, we will create some Beam Reinforcement Cages and add these to parts of your 3D model. We will also save the cages as Styles for later use.
1. Open drawing number 7092Model1 and zoom to the Beam at Level2, Gridl ine A. This beam is 400 wide x 600 deep x 4200 long. (You may want to use the ProSteel 3D “HIDE EXCEPT” command to hide all other parts of your model except this beam, related columns, slabs and rebar cages of the model. You can turn all hidden objects back on a later stage with the “ProSteel 3D REGEN” command. and These are the icons for the HIDE EXCEPT command and the PS 3D REGEN command. Both can be found on the ProSteel 3D Display Classes toolbar.
2. Click the “Beam/Column Rebar” button
. You are asked at the AutoCAD command line to “Select Objects”. Click the beam at the Level 2 - gridline A, and then right click to avoid choosing more columns. A reinforcement cage is automatically added to the beam, and the “ProConcrete 3D Single-Cage Reinforcement” dialog box appears. Notice that the end conditions shown at the start of the beam are coloured green, the end conditions at the end of the beam are coloured red. Changing values in the dialog box will change the appearance of the cage just placed. Fill out the values in the dialog box as shown below. As you use the cells and drop-down lists in the dialog box, so the beam rebar cage on the 3D model will change to reflect your cage design. We will create a beam cage that has 2 top longitudinal bars, and 4 bottom longitudinal bars. All ends of longitudinal bars will be bent so that on site they can be tied to the vertical main bars of the column cages. Also the stirrups will be generally at 300mm crs, but with hinge zones area at each end of the beam, where the stirrup spacings will be 150mm.

Editing Rebar Cage Elements Rebar cages can be manually edited using any of the rebar editing tools provided with ProConcrete 3D. Most of these rebar editing tools are found on the following toolbars:
Tools are included for adding and editing rebar end conditions, deleting end conditions and stirrups, breaking and joggling bars, moving and rotating bars. There are also tools for creating new bars (either attached to concrete objects or existing rebar cages), and for stretching and trimming bars. ProConcrete 3D modelers can use one or many of these tools to perform editing on individual bars and standard rebar cages, thus enabling you to create any imaginable nonstandard rebar cage, rebar set or individual rebar. These tools could also be used to create starter bars, starter bar sets, or complex wall and slab bars. Some of these editing type tools are explained below. This button is used to access the PROCONCRETE 3D EDIT REBAR TOOLS dialog bog. This dialog box contains many of the tools also found on the “ProConcrete 3D Edit Rebar Tools” toolbar.

It will only allow you to stretch individual rebar cage bars that have been placed when using the “ProConcrete 3D Create Standard Beam Column Reinforcement” command or similar. Use it to stretch the end of a vertical or horizontal bar by the supplied amount. The stretch can be in a positive or negative direction, enabling you to create a longer or shorter bar.
This is the TRIM REBAR button. It will only allow you to trim original bars that have been placed when using the “ProConcrete 3D Create Standard Beam Column Reinforcement” command or similar. Use it to trim away the end of a vertical or horizontal bar. You are asked to pick the bar at the portion to be retained, and you are asked to pick a point indicating where the trimming occurs.
This is the ADD PANEL REINFORCEMENT - REBARSET button. It will allow you to add a rebar set to panels and walls. Use of the command presents you with the “ProConcrete 3D

Exercise 12-1 Editing Beam and Column Reinforcing In this exercise, we will edit some Beam Reinforcement Cages by breaking and joggling the main horizontal top bars and shortening some of the horizontal bottom bars. You will also edit some vertical column bars.
1. Open drawing number 7092Model1 and ensure that you are viewing the complete model by use of the Isometric Overview 1 button . Zoom to the concrete beam at the top of the columns at Gridline A. (You may want to use the ProSteel 3D “HIDE EXCEPT” command to hide all other parts of your model except this beam, related columns, slabs and rebar cages of the model. You can turn all hidden objects back on a later stage with the “ProSteel 3D REGEN” command.)
2. Click the “Break and Joggle” button
, located on the “EDIT REBAR” toolbar. You are asked at the AutoCAD command line to “Select Rebar”. Click the top front bar of the rebar cage that exists at this beam. The horizontal bar will highlight in red, and you are then asked at the command line to SPECIFY A LAP POSITION. Answer with the P for POINT, and osnap to the midpoint of any top edge of the concrete beam. The break and joggle appears at the picked point. The dimensions for the lap are set by the rebar database files chosen in the ProConcrete 2D OPTIONS dialog box. The AutoCAD command line will now ask you to choose more rebar. This is because the “Break and Joggle” command allows you to repeat for many horizontal bars. Place a Break and Joggle on the top rear horizontal bar for this beam, then finish the command with a right click. Your beam laps should now look like this.
3. Now use the DELETE END CONDITION button
to remove the bent ends from both
ends of the central bottom bars at this beam. After clicking the button, you are asked at the command line to SELECT REBAR. Pick one of the horizontal bars at the left end which is to have the bend end condition deleted. 176 Copyright © 2009 Bentley Systems, Incorporated
Mar-10
Editing Rebar Cage Elements
(You do not have to pick the actual bend). The bend end condition is removed, and you are again asked at the command ine to SELECT REBAR. Select the second horizontal bar at the left end, and the bend end condition is removed. Repeat this for the right hand end of the same two horizontal bars, and finish the command with a right click.
4. Now click the STRETCH REBAR button
, so that we can stretch the same 4 ends dealt with a Step 3, such that they are 500mm shorter. AT the AutoCAD command line you are asked to SELECT REBAR. Pick one of the bottom longitudinal bars at the left hand end. The bar is highlighted in red. You are then asked to select the base point for the stretch, select any point. With ortho on, move the mouse pointer in the required direction and type 500, then either the right mouse button or the enter button on the keyboard to finish. The bar is stretched shorter. Again you are asked at the command line to SELECT REBAR. Pick the second longitudinal bottom bar, and repeat the above for the distance. Keep repeating this for the other two ends of these same longitudinal bars. Your beam rebar cage should now look like this.
5.

Click the “Rebar Properties” button (found on the Beam/Column toolbar) so that we can edit the top of the vertical bars within the column at the left hand end of the beam shown above. (You can alternatively highlight the column cage, and right click and choose PS3D Properties from the context sensitive right click menu) At the AutoCAD command line you are asked to SELECT A STANDARD CONCRETE OBJECT to edit its cage. Click the left hand column object (not the left hand cage). The “ProConcrete 3D SingleCage Reinforcement” dialog box appears, and the values within the dialog box are those that are currently applied to the rebar cage. We will use the END CONDITIONS tab of this dialog box to edit the bar ends. Fill in the values shown in the following diagram.

6. The values that need to be changed on the “END CONDITIONS” tab shown on the previous page include the TOP END (Bend Type, -165 offset), the LEFT END (None Type, 50 offset), the RIGHT END (None Type, -50 offset) and the BOTTOM END (Bend Type, 195 offset). Ensure that the Finish the dialog box with the OK button.
7. Repeat Steps 5 and 6, but this time for the top of the vertical bars within the column at the right hand end of the beam shown in the step diagram. When finished your beam at Level 2 of your building should look like this.
8. Click the ProSteel 3D Regen command
to make all parts of your model visible again.
9. Now repeat Steps 1 through to 7, but this time for the horizontal beam at Level 2, along gridline E. The beam and columns at Gridline E should end up looking similar to the beams and columns at gridline A. Click the ProSteel 3D Regen button to redisplay all previously hidden objects. Now save your drawing to hard disk.

Exercise 12-2 Additional Beam Reinforcement In this exercise, we will add a new Beam Reinforcement Cage to the long balcony beam at gridline C, Level 2. We will then edit the beam ends.
1.
View your complete 3D model with the Isometric Overview 1 button, and then zoom to the long beam at Gridline C, Level 2, the beam running between Gridline 3 and the midpoint of the arced area of the building. Use the ProSteel 3D HIDE EXCEPT command to hide all objects in your 3D model except this concrete beam, and any columns, beams and rebar cages adjoining it. (Ensure that any slabs and precast slab panels are hidden.)
2. Now click the “beam/Column Rebar” button
to begin adding a rebar cage to this beam. You are asked at the AutoCAD command line to “Select Objects”. Click the beam at Gridline C, then right click to avoid choosing more beams. A reinforcement cage is automatically added to the beam, and the “ProConcrete 3D Single-Cage Reinforcement” dialog box appears. Fill out the values in the dialog box as shown in below.

Finish the command and the dialog box with the OK button.
3. Now draw a construction line across the top face of the concrete beam reinforced in the previous steps. Ensure that this construction line is drawn on Layer 0. Ensure that this construction line is drawn at the midpoint of the beam (use the MID osnap) with the AutoCAD LINE command, and is drawn 90 degrees to the long direction of the beam. Then offset the line 1500mm either side of the midpoint construction line. These two new construction lines will be used to BREAK and JOGGLE the top two horizontal bars of the beam rebar cage.
4. Click the “Break and Joggle” button
, located on the “ProConcrete 3D Reinforcement Tools” toolbar. You are asked at the AutoCAD command line to “Select Rebar”. Click the top front bar of the rebar cage that exists at this beam. The horizontal bar will highlight in red, and you are then asked at the command line to SPECIFY A LAP POSITION. Answer with the P for POINT, and osnap to any end of the leftmost construction line drawn at this concrete beam. The break and joggle appears at the picked point. The dimensions for the lap are set by the rebar database files chosen in the ProConcrete 2D OPTIONS dialog box. Either press the enter button on the keyboard or press the right mouse button to repeat the “Break and Joggle” command, then place more Break and Joggles on the top two horizontal bars for this beam, at the leftmost and rightmost construction lines, then finish the command with a right click. Your beam rebar laps should now look like this.

5. You may notice that the leftmost joggle occurs in the wrong direction. We can f ix this by removing the joggle, stretching the horizontal bars so that they meet, and then adding a joggle to the correct bar.
6. Zoom closer to the 2 top horizontal bars, at the leftmost break and joggles. Click the DELETE END CONDITION button
, when you are asked at the command line to
SELECT REBAR, pick either of the joggled bars at this end (these are the bent and lapped bars). The end conditions may be coloured red or green. The joggle is removed, and you can repeat this procedure for the second of the joggled bars. Finish the command with a right click. After removing these joggles, you should be left with a large break between horizontal bars. Your beam rebar cage should now look like this.
7. We need to close the breaks at the left side of the beam rebar cage with the STRETCH REBAR button . Measure the distance across the break f irst. You can use the AutoCAD DISTANCE command to do this. Keep a note of the distance measured (it may be 481). Now click the STRETCH REBAR button. You are asked at the AutoCAD command line to SELECT REBAR. Pick a horizontal top bar to the right of the break (nearest the mid section of the beam). When asked to select a base point, select any point, then move the mouse pointer in the required direction and enter the value of 481. The right bar is now lengthened to meet the left bar. Repeat this step for the break at the second set of top horizontal bars. Finish the command with a right click.
8. Now click the JOGGLE button to begin adding joggled laps at these two break points. You are asked at the AutoCAD command line to SELECT REBAR TO STAY. Click the front right horizontal bar at the break mentioned in Step 7. You are now asked to SELECT REBAR TO MOVE. Click the front left aligned horizontal bar. The joggle and lap is automatically created, and the end condition is shown as either a red or green colour. The length and dimensions of the joggled end condition is set by the rebar standards database file defined back in the ProConcrete 3D OPTIONS dialog box. Repeat the JOGGLE command for the rear break. When completed your beam should look like this.

Creating User Shapes
Overview In this chapter, you learn about creating concrete User Shapes, and then adding them to your models. You will also learn how to add rebar to them.
Objectives In this chapter, you will:
Learn how to use the User Shape feature. Add some user shapes and standard shapes to a new model. Get an overview of the Create User Defined Beam Column Reinforcement feature. Add some user defined reinforcement to user shapes.
This manual presents fundamental concepts you need to know about the modelling process in ProConcrete 3D. The tutorial is not necessarily best practice of structural concrete design but focuses on using various ProConcrete 3D commands.
Mar-10
185 Copyright © 2009 Bentley Systems, Incorporated
User Shapes (Special Shapes)
User Shapes (Special Shapes) By using the special shape management of ProSteel 3D, you can add your own custom shapes to the program which will then be processed like catalogues containing any number of shapes, i.e., you can establish same sorting as with standard shapes. The selection menu then shows catalogue names as a shape type and the shapes contained in each catalogue appear as shape size, making it easy to choose between different system shapes. You can create special shapes as combination of existing shapes or by using a drawn cross-section or a variant (qualitative generation instruction) with corresponding data base. The program once again manages these shape catalogues in four special shape master groups, which all basically have the same properties and are consequently described together in this chapter. There is a distinction between general special shapes, roof-wall shapes, combination shapes and weld shapes. You create the first two groups by drawing a cross-section; for combination shapes you combine existing shapes to create a new shape (e.g. two U-shapes welded together). The weld shapes are created using a special dialog. For ProConcrete 3D we deal primarily with User Shapes. Roof-Wall Panels, Combination Shapes and Weld Shapes are generally for use with ProSteel 3D. You can store each shape in three different display modes (low, normal and high – which must be created individually). You thereby avoid having to deal with a confusing number of lines when working with rather complex shapes, but you can show the complete shape if needed. Nonetheless, you can always select the ProSteel 3D standard display modes (only center line, envelope, etc.) without having to change any parameters. Here, you see the dialog for special shape management.
It is organized in a tree structure and consists of 4 main tabs for the different types of special shapes. Each of these branches can contain subordinate directories and each subordinate directory can have any number of special shape definitions. However, you cannot make any further subordinate division. Select a shape and the stored crosssection will be displayed on the right monitor. 186 Copyright Š 2009 Bentley Systems, Incorporated
Mar-10
User Shapes (Special Shapes)
Creation of a Catalogue -Select one of the tabs to layout a catalogue and use the right mouse button. A subordinate menu is displayed offering you the option to layout a catalogue. A subordinate directory is created and you can edit the name.
Creation of a Special Shape A special shape layout is made analogously to the layout of a catalogue. Select the desired catalogue and use the right mouse button. Then, you can select the option Layout Shape. Enter the name and the shape appears as an entry. This name is the access name and not the name, that later will be displayed in a parts list. Please note that until now you only created a blank cover that has to be filled with creating a resolution. It is not before then that the special shape has been filed. If you don’t do that, the blank shape cover will be removed at next selection. Layout of a Depiction Resolution After the layout of a blank special shape definition has been affected, you have to define a resolution. Select the shape and use the right mouse button again.
Here, you select the desired resolution. If resolutions have already been defined for the special shape, you can modify the defined resolution using this method. Definition of Cross-Section Defining the closed and the not crossing contour of the cross-section define a special shape. Depending on the setting, this can be done using poly-lines or individual lines and arc segments. You have to take care that these build a closed contour. After selection, choose your outer contour and any existing inner contours. You can utilise any number of inner contours that, must not cross the outer contour and must not they have any intersection points between each other.

187 Copyright Š 2009 Bentley Systems, Incorporated
User Shapes (Special Shapes)
Now, the program automatically determines the possible insertion points of this shape (center, envelope). Finally, you can still define any additional insertion points. Alternatively, you can define special shapes of regular thickness by using a poly-line contour and by specifying a thickness. After end of definitions, the properties dialog for the parts list data will be displayed.
Enter the name of the parts list, notes, material, etc. Starting from the crosssection drawing and the entered material data, the program calculates the weight in kg/m and displays it in the entry field Weight. Here, you can determine which shape data will be applied to the standard parts list and you can change the weight.
When you close this dialog, the selected resolution has been defined and the special shape layout is finished and the special shape can then be selected and utilized. As you can see, the defined resolution is displayed. Now, you could repeat this procedure with different resolutions or modify any existing resolution as described above.

User Shapes (Special Shapes)
Exercise 13-1 Creating New User Shapes In this exercise, we will create 2 new User Shapes for future use. One will be Concrete Strip Footing, the other will be a special Precast Flooring System Shape.
1. Save and then close your previous model (Drawing 7092Model1). 2. Start a new drawing. From the AutoCAD FILE pulldown menu, choose NEW from the list of commands. You should then see the AutoCAD SELECT TEMPLATE dialog box. Choose PS180_Metrisch.dwt from the list of available drawing templates, and then click the OPEN button at the bottom right of the dialog box. The new drawing is created, and probably named something like Drawing1.dwg or drawing2.dwg. (The new drawing has nothing drawn in it, but it does have default ProConcrete Layers within it. The viewpoint is an isometric one, as you will see by the UCS icon.)
3. Save your drawing with a better name, and to a more appropriate folder by use of the AutoCAD SAVEAS command (located under the AutoCAD FILE pulldown menu). Save your drawing as filename 7092Model2.dwg to the same folder where your 7092Model1.dwg file is kept. (This should be the C:\Cad Projects\7092\Model folder).
4. Now click the “Plan View” button
, located on the ProSteel 3D Viewtools toolbar. This will give you a plan view of your model. (We have no drawn entities yet within our drawing, so it will still look like an empty drawing).
5. Use the AutoCAD POLYLINE command to create 2 closed polylines as shown in the diagram below. Draw the polylines only, not the dimensions, text or hatching. Ensure that the polylines are closed. You may draw them anywhere you like within the drawing. Your current drawing layer should be Layer 0.

6. Click the “Create User Shape” button
, available from the ProSteel 3D Partlist and Export toolbar. (Or alternatively from the ProSteel 3D pulldown menu, pause your cursor over the OTHERS option, and you will see a flyout menu with more options. Choose CREATE USER SHAPE from this menu). You are now presented with the “ProSteel 3D User Shape Manager”. Check that your settings are as for those shown in the diagrams below, and highlight the USER SHAPES option on the User Shape Manager tab.
7. Right click the USER SHAPES option, and from the pop-up menu choose CREATE A NEW CATALOG. The User Shape Manager will have a new cell added to the list of existing catalogs. Its name will be Catalog. Rename it to PC3D-Training-Footings (as shown below).
8. Highlight and then right-click the catalog entry “PC3D-Training-Footings”, and from the pop-up menu choose CREATE USER SHAPE. A new cell will in the dialog box, below the entry. It will by default be called SHAPE. Rename this to FB-600-200.

User Shapes (Special Shapes)
9. Highlight and then right-click the user shape entry FB-600-200, under the “PC3DTraining-Footings” catalog, and from the pop-up menu choose CREATE NORMAL RESOLUTION. You are now asked at the AutoCAD command line to SELECT OUTER POLYLINE. Pick the first of the polylines drawn at step 5 of this exercise. (The one labeled FB-600-200 in the diagram at step 5.) When you are asked at the AutoCAD command line to SELECT MORE INNER POLYLINES, click Enter on your keyboard. (There are no inner polylines, as the footing beam is not a hollow shape). You are now asked at the AutoCAD command line to SPECIFY MORE INSERTION POINTS. This is where you can pick additional points that can be used for insertion purposes. OSNAP to the points shown on the following diagram, then hit enter to move on. When you are asked at the AutoCAD command line to SPECIFY MORE INSERTION POINTS for the polyline OSNAP to and pick the points indicated by the filled circles on this diagram. (The points in this case are always at the ends of the polyline segments.)
Nine default points for insertion will be available when placing shapes. You do not need to choose these points. They are indicated on this diagram by hollow circles. (Notice the 9 points are equally surrounding the complete polyline as if it were within a rectangular area.)
10. You will next see the User Shape Properties dialog box. This allows you to attach hidden data to the shape. This hidden data is available for extraction when creating partlists, bar bending schedules, and 2D detail drawings. Fill out the details within the dialog box as shown below. Choose the Material from the available drop-down list. Make the NAME the same as the name used at Step 8 of this exercise. Finish with the OK button.

11. When asked at the next dialog box DO YOU WISH TO OVERWRITE, click the OK button to answer yes. (Although you have not yet stored the User Shape, you do have a User Shape named in the list of available shapes.) You are now back at the “ProSteel 3D User Shape Manager” dialog box. Click the OK button on this box. Your user shape creation is now complete. The user shape will now be available to be used with the “ProConcrete 3D create Beam column Shape” command.
12. Repeat Steps 6 to 11, but this time for the second of the polylines that was drawn at Step 5. This polyline represents the double tee Flooring Panel shape. When asked to CREATE A NEW CATALOG, name it PC3D-Training-FloorPanels. When asked to CREATE USER SHAPE, name it TT-1200-600. When asked to SPECIFY MORE INSERTION POINTS, osnap to the points indicated by filled circles on the diagram below. When the “User Shape Properties” dialog box appears, adjust the dialog box for the values shown below. Finish as per Step 11.
192 Copyright © 2009 Bentley Systems, Incorporated
Mar-10
User Shapes (Special Shapes)
13. You now have two new User Shapes that can be used in your current modeling project, or in future modeling projects. As the polylines used for creating these user shapes are not needed again, you can either delete them or move them to an unused and nonplottable layer. If deleting them from your drawing, then you will be left with no visible entities within your current drawing S005.dwg.
14. If you are interested in where your User Shape has been stored, then please use Windows Explorer, or My Computer, to browse to the following folder, C:\Program Files\Bentley\ProSteel 3D\R18.0\AutoCAD 2008\Data\UserShapes (or similar). You should see that this folder now has 2 subfolders called \PC3D-Training-FloorPanels and \PC3D-Training-Footings. These folders contain the newly created User Shapes. These shapes are stored as .psp files. These are data files cannot be used by the AutoCAD INSERT command. They are not in any way like AutoCAD blocks. You can only use these shapes with the “ProConcrete 3D create Beam column Shape” command.

User Shapes (Special Shapes)
Exercise 13-2 Creating User Shapes Within a Model In this exercise, we will create a new Workframe, and insert some User Shapes and Standard Shapes onto the Workframe lines.
1. While still within your 7092Model2 drawing, click the Isometric Overview 1 button to return to a default isometric view.
2. Use the AutoCAD RECTANGLE command
to draw a rectangle that is 6440 wide (in the standard X direction) and 12 000 long (in the standard Y direction). The rectangle will be drawn at the 0 Level, and the front left corner will be at the 0,0,0 point of the drawing. It should be drawn on the 0 Layer (because this should be your current default drawing layer), and because you have used the RECTANGLE command, the resultant rectangle is actually placed as a closed polyline.
3. Click the “Create User Beam/Column” button
, and the “ProConcrete 3D Beams and Columns” dialog box appears. Fill in the values of the dialog box as shown below. Ensure that the insert point used is the top right insert point as shown by the red circle in the preview area of the dialog box. This insert point is not on a concrete edge, but in this case it will not hinder the placement of our footing beams.
194 Copyright © 2009 Bentley Systems, Incorporated
Mar-10
User Shapes (Special Shapes)
4. When you are ready, click the “Insert Beam by 2 points” button
within the dialog box. You are asked at the AutoCAD command line to Specify Start Point, OSNAP to the front right corner of the rectangle drawn in the previous step. You are now asked to Specify End Point. OSNAP to the front left corner of the rectangle. The beam is placed, and the command line allows you to rotate the shape. Our beam should beam aligned such that the recessed top edge is to the outside of the rectangle. As we do not need to rotate our shape, right click so that we can place another footing beam. You are again asked at the command line to pick a start point, and then an end point for the shape. OSNAP to the front left corner of the rectangle, and then the rear left corner. The beam is placed. Repeat this for the next two edges of the rectangle. Finish the command and the dialog box with the OK button at bottom left of the dialog box.
5. You may have noticed that the beams are probably created with a grey colour. This is because they have automatical ly been placed on the PC_BEAM layer. You can if you wish move them onto any other AutoCAD layer. Select the four footing beams that you have just created, then from the dropdown of layers on the AutoCAD Layers toolbar, choose PC_STRIPFOOTING. The beams now appear in a cyan colour. They have been moved to the default ProConcrete layer set aside for strip footings.

6.
and You may also notice that the beams currently clash with each other at the corners. They overlap. Use the Mitre Cut button on the SHAPES tab of the “Element Modification” dialog box to tidy all of the four corners. When completed, your model should look similar to the one shown in the diagram below.
When you are asked to SPECIFY START POINT at Step 7, OSNAP to this outside corner of the beam junction. Note it is 150 below the rectangle drawn at Step 2.
7. We will now place an in-situ wall around each side of the rectangle. Click the “Create Precast Panel” button , and you will then see the “ProConcrete 3D Wall ” dialog box. Ensure that your dialog box values match those shown in the diagram shown below.
8.
Click the “Insert a Wall by Specified Points” button near the bottom left of the dialog box to begin placing the wal ls. You are asked at the AutoCAD command l ine to SPECIFY START POINT. Osnap to the left front mid-height outside corner point of the front footing beam. This corner point is at a level 150 below the front left corner of the rectangle drawn at Step 2. (See the diagram shown at Step 5 for this point.) When asked 196 Copyright © 2009 Bentley Systems, Incorporated

to specify the next point, OSNAP to the subsequent rear left corner point. Repeat this for the next 2 points (picking points in a clockwise sequence), and then pick the first of these points again. (The front left corner of the rectangle). Finish with a right click for Enter. The wall is created. You can finish the dialog box and the command with the OK button.
9.
and Create a doorway through the left side wall segment, and through the right side wall segment. From the “Element Modi f ication” dialog box, click the ENABLES TO ADD A DOOR TO A WALL button to begin placing the door penetrations. Ensure that the dialog box values are as shown below right. When you are asked at the AutoCAD command line to PICK THE WALL IN WHICH A DOOR SHOULD BE INSERTED, pick the left wall near the bottom outside midpoint.
10. When you are then asked at the command line to PICK INSERTION POINT FOR WALL OPENING, osnap to the bottom midpoint of the previously selected wall. The doorway is placed, the left side of the doorway is at the insertion point. Repeat this for the right wall. When complete, your model should look similar to that shown in the diagram below left.

12.
Click the “Insert Beam by 2 Points” button near the bottom left of the dialog box to begin placing the floor panel. You are asked at the AutoCAD command line to SPECIFY START POINT. Osnap to the outside top midpoint of the front wall (the short wall that has no doorway). When asked to SPECIFY END POINT, osnap to the outside top midpoint of the rear short wall, at the other end of the building model. Right click to stop placing further panels, and finish the dialog box with the OK button.
13. The panel that you have placed sits too low. Use the AutoCAD move command to move it upwards in the Z direction by 150mm (The thickness of the top portion of the panel.)
14. Copy the panel 2 more times to the left of the first panel, and 2 more times to the right of the first panel, such that there are 5 complete panels, spaced 1210 apart. (This will create a 10mm gap between panels).
15. You may notice that the legs of the double tee flooring panels probably clash with the in-situ walls under. We will check for clashing that occurs in our current model in a later chapter.
16. The top end edges of the panels currently finish f lush with the outside edges of the insitu walls. Shorten each of the panel ends by 140mm, such that the panels will have a final seating depth of 50mm. Use AutoCAD GRIP editing techniques to achieve the shortening. You will find that all User Shapes only have two grip points. One at each end of the user shape.
17. Your existing ProConcrete 3D model should now look similar to that shown below.

Adding Rebar to User Shapes
Adding Rebar to User Shapes Rebar cages can be added semi-automatically to user defined User Shapes by the use of the “Add User Shape Reinforcement Cager” command. The command allows you to place and size all bars needed for a user defined Column Rebar Cage or a Beam Rebar Cage. Top bars, bottom bars, side bars and stirrups can all be designed by the user. The bar lengths are determined automatically by the length of the user shape being used, and the values placed in the dialog box cells. There is no need to manually input the length of user shape bars. Bar ends can also be designed with or without projections, and bends if required. The dialog box used for adding rebar to ProConcrete 3D User Shapes is called the “ProConcrete 3D UserShape” dialog. It has three tabs, they are documented below. The REBARS tab shown below allows you to design the longitudinal rebars for User Shapes. You initially chose a rebar size and cover, then use the PICKLINE button to indicate a side to apply rebars to. You decide how many bars for each side, and their end conditions. When you have designed one side, you use the PICKLINE button to move onto and then design the next side. A preview diagram to the right side of the dialog box shows you your chosen design as you are completing it.
The dashed line around the inside edge of the User Shape (shown in the preview area) indicates the cover distance to rebars. The dashed lines will help you design your rebar cage.

Adding Rebar to User Shapes
These buttons are used to help you manage your rebar design. The minus button is used to delete badly designed rebar sets, the arrow buttons are used to move between the rebar sets (when you have more than one set).
The STIRRUPS tab shown below enables you to create stirrups to suit the different areas of your User Shape. Stirrup sizes, spacings and types can be chosen from available dropdown lists. You use the PICKREBAR button to define rebars that control the stirrup corners. When you have designed one stirrup type for a particular area of your User Shape, you use the PICKREBAR button to move onto and then design the next stirrup type for the next area. A preview diagram to the right side of the dialog box shows you your chosen design as you are completing it.
The PICKREBAR button allows you to “pick rebars” in the preview area to use for the design and layout of your stirrup. You can click this button several times to add and design several stirrup sets within your single rebar cage.
These buttons are used to help you manage your rebar design. The minus button is used to delete badly designed stirrup sets, the arrow buttons are used to move between the stirrup sets (when you have more than one set). The TIE FLIP option allows you to flip stirrups upside down, so that stirrup ties may be at the bottom of the stirrup, rather that at the top.

13. After clicking the PICKREBAR button, you need to pick two aligned rebars shown in the preview area of the dialog box. Click the two topmost end rebars as shown above. They will highlight in red colour, and you will probably see a tied type stirrup added. In the Stirrup tab, check the option TIE FLIP. Click into any other cell of the dialog box to force the change to occur, and you should now see a tied stirrup across the top portion of your user shape inside the preview area. You should also see stirrups drawn in your ProSteel double tee model.
14.
Now click the PICKREBAR button again to begin defining more rebars for a stirrup set. (Ensure that your Stirrup Type dropdown list is set to RecLap, and Insert Offset dropdown list is set to Back). Pick the two outermost bottom rebars in the left rib, and pick the two top rebars directly above. Click into any other cell of the dialog box to force the change to occur, and you should now see the stirrup added to the left rib within the preview area. You should also left rib stirrups drawn in your ProSteel double tee model. (Note: If you have problems setting the stirrup type, as well as picking the rebars to define the stirrup corners, you can choose to use the REPICK button, to redefine the stirrup corner points).
15.
Click the PICKREBAR button one more time to begin defining stirrups for the right rib of your double tee user shape. Use a similar technique and settings as described in Step 8 above. When finished, your model and preview area should look like that shown below.
16.
If you wish to, you may at any stage return to the Rebars tab of this dialog box and use the arrow buttons to return to any Rebar Set within the Rebar cage and redefine that particular rebar set. You can also delete a rebar set with the minus button, and then use the PICKLINE button once more to begin adding an additional rebar set.

Adding Rebar to User Shapes
21. Erase all of the double tee user shapes that currently do not have rebar cages attached to them. (There should be 4 double tee user shapes to erase).
22. Now copy the only remaining double tee user shape, and its rebar cage, using the AutoCAD COPY command. Copy the double tee in such a way that there are 5 complete double tees with cages when finished. The double tees should be spaced 1210mm apart, as was done at Step 12, in exercise 13-2. When complete, your 3D model should look like that shown in the diagram below. (Note: Ensure that 2 complete objects are selected to copy, the double tee user shape, and the rebar cage that was applied to it).

Collision Detection
Overview In this chapter, you learn about inspecting your models for clashes that may occur between concrete objects, and reinforcing bars.
Objectives In this chapter, you will:
Learn about the Collision Detection tool. Check your existing model for collisions. Learn about the ProSteel/ProConcrete 3D COPY command. Modify your model at areas where collisions occur. This manual presents fundamental concepts you need to know about the modelling process in ProConcrete 3D. The tutorial is not necessarily best practice of structural concrete design but focuses on using various ProConcrete 3D commands.
Mar-10
209 Copyright © 2009 Bentley Systems, Incorporated
Collision Detection
Collision Detection There is a ProSteel 3D /ProConcrete 3D feature that allows you to check for collisions (clashes) between objects. This feature is called Collision Detection. It was primarily designed for use in ProSteel 3D to detect collisions that might occur in steel structure. This feature has been extended for use within ProConcrete 3D, such that you can check for collisions that may occur between concrete objects, and collisions that may occur between rebar objects. The “Collision Detection” command icon can be found on the ProSteel/ProConcrete 3D Edit toolbar, and on the ProSteel/ProConcrete 3D Collision Detection toolbar, or choose “Collision Detection” from the ProSteel/ProConcrete 3D / Additions pulldown menu. An important task of modern 3D CAD systems is to avoid errors during modeling. First and foremost is to avoid collisions. The ProSteel 3D Collision Detection command serves for the detection and display of collisions between any types of 3D components. There are various reasons for collisions to occur. The collision detection check is made on the basis of the 3D component volumes. If a collision is detected, the collision volume is displayed on screen, and the components in question are highlighted. You can then zoom in on collisions, one after the other, and modify your 3D model to suit. (This functions points out collisions occurring, it does not automatically fix collisions for you). Use of the Collision Detection command presents you with the “Collision Check” dialog box. It has 3 tabs, and several buttons allowing you to use the feature.
The VALUES tab has default settings that are used in the detection process. It is recommended that for most ProConcrete 3D users, that you do not change these default settings. Min. Volume setting is in cubic mm, and is used for finding collisions. Display Scaling sets the display factor when automatically zooming to found collisions. (This is apparent when using the arrow buttons)
210 Copyright © 2009 Bentley Systems, Incorporated
Mar-10
Collision Detection
Actual/Max displays which collision you are zoomed to, and how many total collisions occur. (This is apparent when using the arrow buttons) Get All Collisions, when unchecked allows you to use the OPTIONS tab.
The OPTIONS tab allows you to choose which parts are considered when using the collision detection command. You can choose parts from the list if “Get all Collisions” is left unchecked on the Values tab. Please note that the OPTIONS tab is primarily used for ProSteel 3D objects, not ProConcrete 3D objects.
Please note that the time taken by the software to find collisions and highlight them can vary greatly, depending on how many components are selected for the collision detection. The more components selected, the more time needed to check for collisions. The CONCRETE OPTIONS tab is primarily for use with ProConcrete 3D, rather than with ProSteel 3D. It allows you to check for Concrete collisions and Rebar collisions. You can turn off either or both options.
Mar-10
211 Copyright © 2009 Bentley Systems, Incorporated
Collision Detection
The SELECT button starts the collision check process. You are asked to select parts before the check occurs. After the check has completed, all col l iding components will generally be displayed in a grey colour, and the col l ision volume will normally be created in a magenta colour. (These colours may vary depending on the colours set in the ProSteel 3D OPTIONS dialog box)
The SELECT BOLTS button allows you to check only selected bolts. This button is primarily for ProSteel 3D users.
The DELETES COLLISION BODIES button allows you to globally delete all collision bodies, and return your 3D model to normal colours. Please note that collision bodies are automatically placed on the PS_CRAH Layer. The ARROWS al low you to zoom to any of the found collisions.

Collision Detection
Exercise 14-1 Collision Detection In this exercise, we will check drawing S005 for collisions between concrete objects only, not rebar objects.
1.
Open your previously created 3D model drawing S005.dwg, if not already open. Click the Isometric Overview 1 button for a zoomed extent wirefame isometric view.
2. As we will only be checking concrete collisions at this stage, and not rebar objects, you should turn off the Layer PC_REBAR. This will reduce the time it takes to perform the collision. Use the AutoCAD dropdown list of layers to turn OFF the layer. (The lightbulb icon is clicked to turn this layer off)
3.
Click the “Collision Detection” command icon which is found on the ProSteel 3D Edit toolbar, and on the ProSteel/ProConcrete 3D Col lision Detection toolbar. You will then see the “Collision Check” dialog box.
4. Check that your Collision Check settings are as shown below.
5. Now click the SELECT button at the bottom of the dialog box. The dialog box will disappear, and you are asked at the AutoCAD command line to select objects. Select all visible objects by use of the AutoCAD window selection tool. Alternatively if you click enter on your keyboard, this will automatically select all visible objects displayed in
Mar-10
213 Copyright © 2009 Bentley Systems, Incorporated
Collision Detection
your AutoCAD drawing window. Right click to finish selecting objects, the dialog box will be visible again. All clashing objects should displayed in a grey colour, and all created clash bodies are displayed in a magenta colour.
6.
You can manually ZOOM or PAN to each clash body with AutoCAD commands. However, the arrow buttons at the bottom of the dialog box can be used to zoom to the clashing objects.
7. The actual collisions occurring in this project appear to be both ends of all of the 5 double tee user shapes colliding with the in-situ concrete walls under. Each end should indicate a magenta coloured collision body. These bodies indicate the amount of collision occurring, and from this, you can manually determine how to modify the double tee ends. (We will modify the double tee ends in the next exercise.)
8. You can use the AutoCAD DISTANCE command to measure the amount of clashing that is occurring at each double tee rib. The overlap amount should be 50mm. (in the Y direction)
9. Please note that the Collision Detection feature is an ideal command for checking your 3D models for collisions only. The collisions are highlighted in colour. No automatic “fixing” of the collision occurs. Nor does the software recommend how collisions should be repaired. It is up to you the user to fix collisions based on your knowledge of concrete structures, and your ability to use AutoCAD and ProConcrete 3D as tools to document your concrete designs.
10.
Click the DELETES COLLISION BODIES button to globally delete all collision bodies from your 3D model, and return your 3D model to normal colours. Finish the dialog box and the command with the OK button. (You can return to the Collision Check dialog box at any stage during the modeling of your project to delete the collision bodies)
Note: It is good practice to delete all collision bodies when not required any longer, as if these bodies are left displayed on your 3D model , they may accidentally be gathered when performing the Positioning task, and the 2D detailing task. This could result in extra non-required parts being processed for fabrication. Another way of dealing with unwanted collision bodies is to turn off the layer that they are automatically placed onto. By default, all collision bodies are normally automatically place onto the AutoCAD PS_CRASH layer. The default colour for collision bodies is magenta. This normally makes them easy to find on your 3D model.
11. Now turn ON the PC_REBAR layer. (This was turned off at Step 2 of this exercise). All Layers should now be turned on.
12. Click the Isometric Overview 1 button once more to return you to an overall isometric wireframe view, and then save your drawing to hard disk once more.

ProSteel/ProConcrete 3D COPY Command
ProSteel/ProConcrete 3D includes its own COPY button which can be used to copy complete Groups (for ProSteel Users), or individual components parts (for ProSteel users and ProConcrete users). You can copy once only, or multiple times depending on the settings and buttons used. This command also al lows you to Move parts or groups, Turn parts or groups, Mirror parts or groups, Align parts or groups, Clone parts or groups and Rotate parts or groups. You are encouraged to experiment with all of these productive commands which will speed up your 3D modeling.

ProSteel/ProConcrete 3D COPY Command
Use the PART button to Move, Copy, Turn etc a component part only. If this part belongs to a group, it will not affect the outcome. The part becomes a unique part.
Use the GROUP button to Move, Copy, Turn etc complete Groups. (Groups is a term that is relevant to ProSteel 3D users, not so much for ProConcrete 3D users). When you select any part of the group, al l other parts belonging to the group are automatically selected. The resulting objects are complete groups.
This is the CANCEL button. Use it to break out of the command.
This is the HELP button. Use it to access the ProSteel 3D HELP PDF.

Exercise 14-2 Modifying the Double Tees In this exercise, we will modify the ends of the double tee user shapes in drawing S005, where they clash with in-situ walls under.
1. Open your previously created 3D model drawing 7092Model1.dwg, if not already open. Click the Isometric Overview 1 button for a zoomed extent wirefame isometric view. Ensure that all AutoCAD Layers are currently turned on.
2. Erase 4 of the double tee user shapes drawn at the roof area of the model. Ensure that the rebar cages are deleted with the relevant double tees. Do not delete the middle one of the 5 double tees. Do not delete its rebar cage either.
3.
Click the “Hide Except” command icon which is found on the ProSteel 3D Display Classes toolbar. You are asked at the AutoCAD command line to “select objects”. Pick the double tee only, do not pick its rebar cage. All objects except the concrete double tee user shape are now hidden.
4. We know from the previous exercise that the rib ends of the double tee are too long by 50mm at each end. We will shorten the rib ends only (not the slab portion over) by 70mm each end. This will give us a small 20mm tolerance each end. We will perform a Boolean operation to achieve this.
Mar-10
5.
Somewhere close to the front end of your double tee, draw a rectangle that is 1200 wide (in the x direction) and 70mm long (in the y direction). Use the AutoCAD RECTANGLE command to achieve this. The rectangle that is drawn is on Layer 0, your default modeling layer. The rectangle drawn is actually a polyline. Your current UCS should in fact be the default AutoCAD WORLD UCS. The 1200 width of the rectangle matches the 1200 width of the double tee user shape.
6.
Use the ProSteel 3D EXTRUDE command to extrude the rectangle drawn in the previous step by 450mm. This is the depth of the ribs. The EXTRUDE button is located on the ProSteel/ProConcrete 3D Primitives toolbar. It can also be found under a flyout menu on the ProSteel/ProConcrete 3D Edit toolbar. When using this command you are asked at the AutoCAD command line to “Select Polyline”. Pick the rectangle created in Step 5, then right click. You are now asked to “Specify Height”. Answer with 450. A box shaped concrete object, 1200 wide x 70 long x 450 high is created on top of your rectangle. It is created on Layer 0.
7.
Use the AutoCAD MOVE command to move the box shaped object such that it is aligned under the front end of the slab portion of your double tee. Ensure that the box is aligned with the double tee end. See the diagram at right. Erase the rectangle drawn at step 5, as it is not needed any longer.
217 Copyright © 2009 Bentley Systems, Incorporated
ProSteel/ProConcrete 3D COPY Command
8.
Copy the box shaped object to the opposite end of the double tee user shape, and align in a similar manner to the alignment stated in Step 7. Use the ProSteel/ProConcrete 3D COPY command. It is located on the ProSteel/ProConcrete 3D Edit toolbar.
Click the PART button to begin copying the box shaped object. Use this COPY command in a similar way to using the AutoCAD Copy command.
9.
You can now perform a subtract Boolean operation on both ends of the double tee user shape. Click the ProSteel 3D SUBTRACT button, located on the ProSteel 3D Boolean toolbar. (This button is also located as a flyout icon on the ProSteel/ProConcrete 3D Edit toolbar.) You are now asked at the AutoCAD command l ine to “Select the Element from which all Other Elements should be Subtracted”. Pick the double tee user shape. You are now asked to “Select the Parts to be Subtracted”. Select both concrete boxes, and then right click. The Boolean operation is performed. Both ends of the double tee should look similar to the diagram shown below.

10.
You can now turn on all previously hidden objects by using the ProSteel 3D Regen button. The rebar within the double tee, and all walls, slabs and footings will now re-appear.
11.
Click the “Hide Except” command icon once more, and when asked at the AutoCAD command line to “select objects”, pick the double tee user shape, and the rebar cage inside the user shape. All objects except those picked are now hidden.
12.
Shade your 3D model with one of the AutoCAD SHADE buttons. GOURAUD SHADED is an ideal shading mode to use. You should now see that at both ends of your user shape, the longitudinal rib rebars project past the end of the concrete. This will mean that they will clash with the in-situ concrete walls that support the double tee user shape. We will need to modify these rebars such that no clashing will occur. Take note of the bars that need to be shortened (see the diagram below).
13.
Restore shading to its default wireframe mode by use of the AutoCAD 2D WIREFRAME button. It is located on the AutoCAD Shade toolbar.
219 Copyright © 2009 Bentley Systems, Incorporated
ProSteel/ProConcrete 3D COPY Command
14.
Click the STRETCH REBAR button located on the Edit Rebar toolbar. You are asked at the AutoCAD command l ine to Select Rebar. Pick near the end of one of the bottom 3 longitudinal rebars to one of the double tee ribs (select one of the ends nearest the front end of your double tee user shape). The rebar is highlighted in red colour, and you are asked at the command line to Enter Stretch Distance. Type -100 and then enter at the keyboard. The bar is shortened by 100mm, and you are now asked to Select Rebar again. Select another bar. Repeat doing this until all 6 rebars at this end are shortened. Finish the command with a right click.
15. Now orbit, zoom and pan to the opposite end of the double tee user shape. All bottom rebar ends here also need to be shortened by 100mm. Repeat Step 14 at this end to achieve this, however when asked to Enter Stretch Distance, answer with 100 (a positive distance is required here, because the stretch distance is in the opposite direction to the other end of the bars).
16.
Click the Isometric Overview 1 button to see an overall isometric wireframe view of your user shape. Only the concrete shape and rebar will be visible, not the walls and footings hidden at Step 11.
17.
Now GOURAUD SHADE your model once more, then orbit, zoom and pan to inspect for any bars that may extend outside the concrete area. (Note that the top longitudinal bars within the double tee user shape should finish flush with the end of the user shape).
18.
and Click the ProSteel 3D Regen button to restore all previously hidden objects., and then click the Isometric Overview 1 button once more. This will return you to a 2D Wireframe Isometric View of your entire 3D model . Your UCS should also be reset to World UCS if it had been altered to a user defined UCS.
19.
You now have a 3D model that has one double tee user shape at the roof level . We need five of them spaced at 1210mm apart (as was the case in an earlier exercise). Use the ProSteel 3D COPY command to copy the double tee 4 more times (ensure that you copy the rebar cage as well as the double tee user shape). You might want to check the MULTIPLE option of the Copy tab on the dialog box before copying.
20. You may want to orbit, pan and zoom around your model to inspect for any additional clashes. You may at this stage also want to repeat the clash detection command again, as was done in the previous exercise. Save your 3D model to hard disk one more time. It should look similar to that shown in the diagrams below.

Continuous Beams
Overview In this chapter, you learn how to create and reinforce continuous beams (beams that continue over supports, rather than run into them).
Objectives In this chapter, you will:
Learn about the concept of continuous beams. Model a continuous concrete beam with columns. Reinforce a continuous beam with 3 separate rebar cages. Learn how to edit rebar cages within a continuous beam. This manual presents fundamental concepts you need to know about the modelling process in ProConcrete 3D. The tutorial is not necessarily best practice of structural concrete design but focuses on using various ProConcrete 3D commands.

Continuous Beams
Continuous Beams The concept of Continuous Beams within ProConcrete 3D simply means the ability to model and reinforce simply supported beams that pass over supporting columns rather than run into the side of the supporting columns. Continuous Beams can have any number of suitable spans (at least 2 or more spans), and a similar number of support columns. Most of the columns will normally sit under the beam, but can in fact pass through the beam to more continuous beams that may be at higher levels of your structure. Continuous Beams are more commonly seen on multi-storey, concrete framed, simply supported, commercial type buildings. To model continuous beams with ProConcrete 3D may require the use of several commands and features. Reinforcing the continuous beam will also require the use of several ProConcrete 3D commands.

Continuous Beams
Exercise 15-1 Modeling a Continuous Beam In this exercise, we will model a continuous beam that has 3 spans, and 4 supporting columns.
1. Save and then close any drawing files that may still be open. 2.
and Start a new drawing in a manner similar to that used in Exercise 13-1. Start the drawing using an AutoCAD Template. PS180_Metrish.dwt is the template to be used. (You can verify the template has been used if you see a 3D UCSICON). Save your new drawing with the name 7092Model3, back to your current project folder. This should be C:\CAD Projects\7092\Model folder.
3. Draw an AutoCAD LINE, 18 000 long in the Y direction, from the 0,0,0 point. This is the UCS origin if your UCS is still set to World UCS. COPY the line 3600 upwards in the Z direction. You now have two horizontal lines. Connect the two left hand ends of the horizontal lines with a new vertical line (Use the AutoCAD LINE command). Connect the two right hand ends with another vertical LINE. Copy one of these vertical lines at 6000 centres along the length of the 18000 horizontal line. These lines will be used as construction lines when modeling our beam and columns. When finished, your construction lines should look like the figure.
4.
Mar-10
Click the “Create Beam/Column” button to add a 600 x 600 column to the left most vertical construction line. Use the centre of the column as the setout point of the column on the vertical line. Add a second column to the right most vertical line. Use the same setout point. See the dialog box below for the values to be used when placing these columns. Finish the dialog with the OK button.

4. Your “ProConcrete 3D Single-Cage Reinforcement” dialog box should still be open. Make the REBARS tab the current one. Below the right hand cross-section preview area of the dialog box, you will see an area of the dialog box labeled Reinforcement Zone. This area of the preview window indicates the extent of your rebar cage over the length of the beam. Double clicking in the START or END cells will allow you to manually redefine the start or end points for rebar cages. From here we can control how much length of the continuous beam is to have a rebar cage applied to it. There are two cells labeled START and END. As the start of our rebar cage is already set correctly, we can ignore the value of 0. But the END cell currently is set to 17400. This is the full length of the continuous beam. You can type in a modified length in this cell to adjust the length of the cage, however we can double click within this cell to allow us to manually pick a point on the model that will equal the end of the rebar cage. Double click within this cell. The dialog box will temporarily disappear, and you are asked at the AutoCAD command line to PICK THE END POINT of the rebar cage. OSNAP to the top of the second vertical construction line (This is the vertical construction line second from the left that was used to create the 400 x 400 column). The preview area of the dialog box is also updated to show the length of the rebar cage. Now you can finish the command and the dialog box with the OK button. Your drawing model should look similar to that shown below.

Continuous Beams
Another rebar cage is added to the continuous beam that extends for the full length of the beam. We will adjust the length of the cage this time, so that it covers the right hand span only of the continuous beam. On the REBARS tab, in the Reinforcement Zone area of the tab, double click in the START cell, and when asked at the AutoCAD command line to PICK THE END POINT of the rebar cage, OSNAP to the top of the relevant vertical construction line (the one second from the right). The dialog box will return. Click once into any other cell on your dialog box and the rebar cage length will be adjusted. Finish the command and the dialog box with the OK button. Your drawing model should look similar to that shown below.
6. Repeat Step 5, but this time for the middle of the 3 spans that make up the continuous beam. Use the same rebar cage values, but double click the Reinforcement Zone START value cell, and END value cell to adjust the length of the third rebar cage such that it starts at the top of the second from left vertical construction line, and ends at the top of the second from right vertical construction line. When complete, your rebar cage ends will collide, but we will fix this shortly. For the time being, your continuous rebar cages should now look like that shown below.
7.
Click the Isometric Overview 1 button to return to a wireframe isometric view of your 3D model. It is clear from this view that the ends of the rebar cages are not designed efficiently where they meet over the central columns. Save your drawing to hard disk before continuing, then zoom to the area at the top of the second column from the left.
8.
Click the JOGGLE REBAR CAGE button. This can be on the “Edit Rebar” toolbar. When asked at the AutoCAD command line to “Select Cage to Stay” pick the left hand cage (of the 3 cages created). When you are asked to “Select Cage to Joggle”, pick the middle cage. All horizontal rebars are now joggled according to rules set within the ProConcrete 3D database being used, and the bar diameters that were used when creating the bar cages. (The rules used for a joggle are set under the ProConcrete 3D Options dialog box by the choice of Rebar Database File to be used). Length of the lap

Exercise 15-3 Editing a Continuous Beam Rebar Cage In this exercise, we will edit one of the three rebar cages that were added to the continuous beam in the previous chapter.
1. Open your previously created 3D model drawing 7092Model3.dwg, if not already open. Click the Isometric Overview 1 button for a zoomed extent wirefame isometric view. Ensure that all AutoCAD Layers are currently turned on.
2.
Click the “Rebar Properties” button to begin editing a rebar cage. You are asked at the command line to SELECT A STANDARD CONCRETE SHAPE TO EDIT ITS CAGES. Pick the continuous beam drawn on Exercise 15-1, and then right click to enable the dialog box. You will now see the “ProConcrete 3D Multi-Cage Reinforcement” dialog box. Its appearance is almost the same as the “ProConcrete 3D Single-Cage Reinforcement” dialog box.
3. Notice that the bottom of the preview area to the right side of the dialog box lists how many cages are currently within the beam. It also contains arrow buttons to allow you to move between the different cages (for editing purposes). Use the appropriate arrow buttons to make the middle of the three rebar cages your current cage. When using the arrow buttons to define the cage to edit, the current cage will be displayed in red colour in this preview area.
Use the arrow buttons to define which rebar cage will be edited. The numbers indicate which cage is to be edited, and how many cages are attached to the beam. The negative button can be used to delete a cage.
Notice also that in the model, the wanted rebar cage is temporarily highlighted in cylinder mode, while the other two cages are de-highlighted to a grey colour, and displayed in line mode. (This highlighting will return to normal when completing the dialog box with the OK button).

Positioning
All objects have to be positioned before it is possible to start the detailing process, or before creating any partlist. Ensure all parts to be positioned are actually visible on your computer screen before positioning. Only visible parts will be collected during the positioning process. Use the ProSteel 3D Regen command to check whether all component parts are actually visible.
When positioning, note that there is a difference between the position number, and position f lag. A position number is assigned to any part after the positioning process has taken place, and it is accessible by gripping the object and checking ProSteel / ProConcrete 3D Properties / Data. If a part has a position number, it is this number that is inserted into the position flag.
ProSteel/ProConcrete 3D V8i Positioning
Clicking the POSITIONING icon allows you access to the ProSteel 3D Positionflags and Positioning dialog box. This dialog box is used to manage the assignment of position numbers to all wanted parts, groups, rebars and rebar cages within your 3D model. It is also used for the design, management and attachment of Position Flags to those parts and groups.

You can also attach short position flags and mounting position flags. You can also attach a FREE position flag (this is one which is un-related to any specific part or group). SCALE is important when placing positionflags, as they are not real objects. If you have set a ProSteel 3D Scale then that scale will be automatically read into the SCALE cell. This is important if you are placing the flags into modelspace. IN PAPERSPACE is to be ticked if you want the flags to be placed here. You must reach through the AutoCAD paperspace viewport into modelspace in order to select the member to receive the flag. The f lag will be placed in paperspace. A SCALE of 1:1 is fine for Paperspace f lags. STIL: Use the STIL (Style) pulldown l ist to acquire the correct Flag style to be used before actually placing the flags. REGISTER: Checking this cell will write the Position Number into the properties of the object being positioned. When the detail or view is created, the Properties contained in the parts are displayed on the appropriate position flag.
The Distribute tab (as shown above) is used for the automatic placement of Positionflags in views or 2D details. Click the DISTRIBUTE POSITIONFLAGS button to start the automatic placement process. You will be asked at the AutoCAD command line to select all wanted parts or groups. Click this button to exchange the position of two f lags.

ProSteel/ProConcrete 3D V8i Positioning
Exercise 17-1 Positioning Your 3D Model In this exercise, you learn to position all parts created during our 3D modeling exercises.
1. Open your drawing 7092Model1, and then orientate your sample model view into an isometric overview. Ensure that all parts to be positioned are visible. This should include all 3D concrete objects and rebars. It does not matter if 2D construction lines and gridlines are still visible, as the positioning task will ignore them.
2. From the ProSteel 3D Edit toolbar, choose the Positioning icon, or pick Dialog from the ProSteel 3D / Positioning pulldown menu.
You will now be presented with the ProSteel 3D Positionflags and Positioning dialog box. Insert the values according to the illustration shown below:
As we are only interested in Positioning of Concrete parts and rebars at this stage (and not placing Position Flags), then we will only use the Concrete Positioning tab. (The Insert, Distribute, Others, Layout and Sort tabs can be ignored for now.)
3.
After setting the values as shown above, pick the “calls the Dialog for Automatic Positioning” button (this is an OPTIONS type of button). You will now be presented with the Automatic Positioning Settings dialog box. The criteria used to assign position numbers is set with this dialog box. Please take note of the individual explanations using the integrated online help. (Not working at this stage)
4. Now insert the values within this dialog box as shown on the illustration on the next page:

5. After updating the values for those shown above, click the OK button on the bottom left of the dialog box, and you will be back at the ProSteel 3D Positioning dialog box.
6.
Now click on the “Apply Position Numbers to Selection” button on the Concrete Positioning tab of the ProSteel 3D Positionf lags and Positioning dialog box.
7. You are now prompted to select all objects to be positioned. Acquire all objects visible on the screen either by window selecting or picking each object, or type “all” at the command prompt to select all objects.
Note: Note at this stage that even if lines and Workframes are picked, these entities will not be positioned as they are not ProConcrete / ProSteel 3D parts. The result of the positioning is displayed in three different ProConcrete 3D Result Automatic Positioning dialog boxes as shown below. A consecutive number is listed in the first column, and the assigned position number is listed in the second. This list should not be confused with the parts list.
8. Click the OK button for each resultant dialog box.

If the OK button is now selected on both the results dialog box shown above, and the ProSteel 3D Positionflags and Positioning dialog box, then all objects within the 3D model are assigned a position number. The Position No. can be accessed at any time using the normal ProSteel 3D Properties inquiry method. From any ProSteel 3D Properties dialog box, you are able to find the assigned Position No. on the DATA tab of the dialog. Test this by double clicking any ProConcrete object on your 3D model. You could try this for several concrete objects, and for some rebar objects as well. When done, save your drawing to hard disk once more.

Bar Bending Schedules
Bar Bending Schedules and Creating a Bar Bending Schedule is a 2 step process. We will need to create a database of all of the concrete and rebar parts, and then this database will need to be used to create the Partlist or Bar Bending Schedule.
Bar Bending Schedule Creation Clicking the Extract Cage Database button provides you with access to the ProConcrete 3D Bending Schedule Creation dialog box. This dialog box can be used to select various concrete components (beams, columns, walls etc), and the data is then extracted from those components and incorporated into a .dbf file. The user has control over the name of the .dbf file, and its location. The Extract Cage Database button can be found on the “ProConcrete Bar Bending Schedule” toolbar.
The Extract Cage Database button can be found on the “ProConcrete Bar Bending Schedule” toolbar.
You can choose from 3D Elements or 2D Position Flags as your method of Part Selection. A database can be created directly from the model parts (3D Elements) or from any Position Flags displayed on the model (2D Position Flags) as these flags contain data about your model parts. VERIFY POSITION NUMBER – Only parts that have a valid position no. will be evaluated START PARTLIST – Opens the Bending Schedule Print Dialog after extracting partlist.

The ELEMENTS area allows you to select concrete objects to evaluate. The OUTPUT FILE cell allows you to enter the output path and filename. A browse button is provided to help you path the file to a wanted folder.
Bar Bending Schedule Printing Clicking the Print Cage Data button provides you with access to the ProSteel 3D Bending Schedule Print dialog box. This dialog box can be used to display and print any previously created database files that contain rebar objects.
The Print Cage Data button can be found on the “Bending Schedule” toolbar.
The FILE pulldown menu is used to find and select a database file to print. The SETTINGS pul ldown menu allows for editing of report forms used. The DELIVERY pulldown menu allows you to select from two very distinctly different types of Bar Bending Schedule report forms. The DYNAMIC REPORT creates images of rebar at the time of creation. The STATIC REPORT uses standard type images of rebar.

Exercise 18-1 Creating a Bar Bending Schedule In this exercise, you learn to create a database of your ProConcrete 3D model parts, rebar cages and bars, and create a sui table Bar Bending Schedule from this database information.
1. While still in the drawing S001, orientate your sample model view into an isometric overview. Ensure that all parts to be scheduled are visible.
2. From the Bending Schedule toolbar, click the Extract Cage Database button.
You should now see the “ProConcrete 3D Partlist Creation” dialog box. Fill in the values as per the dialog box shown below. Ensure that you name the Output File adequately, and point the f i le for storage to the correct folder on your PC, by using the Enables Selection of File button on the dialog box. Insert the values according to the illustration shown below:
Use the “Enables selection of File” button to browse to the wanted folder where you wish to place the database file.
3.
Click the OK button to accept the dialog box values, and you are now asked at the AutoCAD command line to “Pick Concrete Shapes to Extract Data”. You can select your complete model again by using the standard AutoCAD window selection method. Right click to accept the selection, ProConcrete 3D will extract the data (this may take a short time to complete, depending on your model size), and you should then see the following dialog box if successful.

273 Copyright © 2009 Bentley Systems, Incorporated
Bar Bending Schedules
This dialog box will be used to format and print a bar bending schedule. However, you can cancel this dialog box with the OK button for now, as we will learn how to print the schedule, as though we were to do this at a later stage.
4.
From the Bending Schedule toolbar, click the Print Cage Data button. We will now format and print the Bar Bending Schedule for the complete 3D concrete structure as it stands to date. (The model on drawing number S001)
Our file created at Steps 2 and 3 of this exercise needs to be visible, and selected in the Active Database area of the dialog box. If it cannot be seen, browse to it by using the File pulldown menu. (Note: if you cannot see this file, then browse to the C:\CAD Projects\7092\Model folder) Next, from the Delivery pulldown menu, find and select Dynamic, as your selection of the type of schedule to be used. You will now see a separate dialog box headed Open Database.
274 Copyright Š 2009 Bentley Systems, Incorporated

Bar Bending Schedules
It should show you the available .lst files that can be used for formatting of the schedules. Select the PC3D Dynamic Bar Bending Schedule - Type 1.lst file, and then click the OPEN button. (Note: this file should be located in the C:\Program Files\Bentley\ProStructure\V8i\AutoCAD 2008\Localised\English\PartList\PCBS_Dynamic folder or similar)
5. After clicking the OK button on the Open Database dialog box, you will then see the “Print Options” dialog box. This is similar to the one seen in ProSteel 3D when creating Partlists. From here you need to decide how to print the Bar Bending Schedule. In the case of this exercise, ensure that the DIRECT TO pulldown list within the dialog box is set to PREVIEW. (The resulting Schedule can be previewed on the computer screen rather than printed onto paper). The DIRECT TO pulldown list however could be used to print directly to an attached printer, or to print your schedule to various file types, including HTML files, PDF files, JPEG files, RTF files and XLS files.

6. Click the START button on the Print Options dialog box. A preview of the Bar Bending Schedule is now generated, and displayed on screen. ProConcrete 3D’s inbuilt LIST AND LABEL program generates the Schedule, and is also used to display the preview. You can use the ZOOM button at the top of the preview window to see the schedule in more detail. You should also see thumbnail previews of all of your preview pages down the left side of the preview pane. Your preview pages should look similar to those shown below.

Creating 2D Shop Drawings
The process for creating 2D Shop Drawings in ProConcrete 3D, is very similar to that in ProSteel 3D. We will need to use the ProSteel 3D DetailCenter to create some shop drawing details. We will again just preview these shop drawing details, rather than print them. You will need to find and click the DetailCenter button, located on the ProSteel 3D Details toolbar, or the ProSteel 3D Utilities toolbar to start the DetailCenter. You can also find this function on the ProSteel 3D pulldown menu, under 2D, then DetailCenter. All concrete parts within your model need to have a Detail Style assigned to them before any 2D shop drawings can be created. The DetailCenter can be used to assign the Detailstyles to parts. The DetailCenter can also be used to Preview 2D drawings or to create them ready for insertion into drawing sheets.

Creating 2D Shop Drawings
Exercise 19-1 Preview a 2D Shop Drawing In this exercise, you learn to preview a 2D shop drawing that can be created from one of your 3D model parts.
1. First orientate your sample model view into an isometric overview. Ensure that all concrete parts and al l rebar and rebar cages are visible. Click the DetailCenter button, located on the ProSteel 3D Details toolbar, or the ProSteel 3D Utilities toolbar to start the DetailCenter. You can also find this function on the ProSteel 3D pulldown menu, under 2D, then DetailCenter. The DetailCenter dialog box is a large dialog box that may dock automatically in the left side of your AutoCAD screen. This dialog box can be dragged away from its docked location using the AutoCAD handles, if you wish. (Double click the two grey stripes at the top of the docked dialog box to automatically undock. Double click the blue bar at the top of the undocked dialog box to automatically dock.) Note: If the ProSteel 3D Drawing Information Tablet dialog box appears automatically when clicking the 2D button, then check that the DIT dialog box values are as per those that were used in Exercise 02-1.
2. The ProSteel 3D DetailCenter dialog box opens and displays the ProConcrete 3D Parts in the bottom window. The upper window displays the available Detailstyles (There are only two available concrete detail styles at this stage. “ProConcrete” and “ProConcrete – Lite”.

Creating 2D Shop Drawings
Available Detailstyles are displayed in this area of the ProSteel 3D Detailcenter. A right click in here will allow you to Load, Save or Edit available detai lstyles. You may need to “Load all Detailstyles” in order to find the ProConcrete styles. All concrete parts that make up your current 3D model are displayed in this area. Position numbers are displayed if positioning has been performed. Part labels and sizes are also displayed. The pink diamond indicates that the part is a ProConcrete part, rather than a ProSteel part. Opening this dialog box may take some time, depending on the number of concrete elements in your model. All concrete parts within your model need to have a DetailStyle assigned to them before any 2D shop drawings can be created. To assign these styles, just high ight any concrete part shown in the bottom area of the dialog box, drag and drop it onto the DetailStyle cal led ProConcrete shown in the top area of the dialog box. You will need to assign this style to all concrete parts prefixed Pos.## (These parts are all listed with the pink diamond icon). All steel parts in your 3D model are not yet positioned. Their position numbers are shown as Pos.???. You can use MS windows selection techniques to select all parts at once to assign if you wish. After assigning parts to DetailStyles, the parts

Creating 2D Shop Drawings
should display in the dialog box with a tick against them. Please spend some time now assigning the parts before moving on to Step 3.
3. Now that you have assigned DetailStyles to parts, you can preview what a 2D detail would look like. Go to the VIEWS tab of the ProSteel 3D DetailCenter dialog box. You will see that all parts that have styles assigned are now listed here. Right click a 500 x 500 concrete column part listed in the browser on this tab (there are several 500 x 500 concrete columns to chose from). From the context sensitive right click menu, choose PREVIEW, and you should now see a new AutoCAD drawing in your AutoCAD drawing area, called “Preview Concrete 500 x 500”. You can zoom and pan around this preview drawing. Have a look at what amount of content has been created on this drawing. The content has been controlled by the DetailStyle assigned in step 22-2. You should see a drawing that looks something like this:
4. The Preview drawing can be saved with a new name by using the AutoCAD SAVEAS command. Alternatively the parts listed in the browser can be further processed with the Detai lCenter to produce AutoCAD blocks that can be inserted onto drawing sheets. This is the same process that can be used in ProSteel 3D. Any preview 2D detai l drawing needs to be closed before opening another preview. AutoCAD may crash if you do not close one preview drawing before opening another.
5. Results at this time may not always be ideal. You are encouraged to use the 2D detailing method described in this exercise to see how each of your concrete parts would be automatically detailed. You could try the Detailstyle called “ProConcrete – Lite” on some of your concrete parts. Currently 2D detailing in ProConcrete 3D is a feature that most Precast Concrete fabricators would use often, but it is not considered a feature to be used often by Consulting Engineers for their construction drawings. Consulting Engineers would typically use Paperspace Layouts with many viewports. Workframe views can be projected through these viewports and scaled appropriately. Annotation can then be added either in modelspace or in paperspace.

Objectives
Paperspace Layouts Paperspace Layouts are typically used nowadays by Consulting Engineers to manage the presentation and plotting processes of their design projects. The AutoCAD® window provides two parallel working environments represented by the Model and Layout tabs. Working on the Model tab, you draw a model of your subject. On the Layout tabs, you can arrange multiple "snapshots" of the model . Each layout represents a drawing sheet that can display one or more views of the model at various scales.
The Model tab accesses a l imitless drawing area. In model space, you draw at 1:1 scale, and you decide whether one unit represents one millimetre (for a bracket) or one metre (for a bridge).
Layout tabs access virtual drawing sheets. When you set up a layout, you tell AutoCAD the sheet size you want to use. The layout represents the drawing sheet. This layout environment is called Paperspace.
In a layout, you can create and position viewports, and you can add dimensions, a title block, or other geometry. Viewports display a drawing's model space objects, that is, the objects you created on the Model tab. Each viewport can display the model space objects at a specified scale. You can create multiple layouts in a drawing; each layout can contain different plot settings and paper sizes. By default, a new drawing starts with two layout tabs, Layout1 and Layout2. If you use a template drawing, the default layout configuration in your drawing may be different. You can create a new layout from scratch. Use the Create Layout wizard, or import a layout from a template drawing. When you create a layout from scratch, the first time you select the layout, you are prompted for page setup information. You can right-click a layout tab to display a shortcut menu with options to:
Create a new layout Import a layout from a template drawing Delete a layout Rename a layout Change the order of the layout tabs Create a new layout based on an existing layout Select all layouts Create a page setup for the current layout Plot a layout

Objectives
Exercise 20-1 Setting up the PaperSpace Layouts We will now setup and create 3 Paperspace Layouts, ready for plotting our drawing sheets.
1. Ensure that your ProConcrete 3D project drawing (7092Model1.dwg) is open, and from near the bottom left of your AutoCAD window, left click the tab “Layout 1” to make that Paperspace Layout the active one. The Page Setup Manager dialog box may now be visible. If not, right click the Layout 1 tab, and from the context sensitive menu provided, choose “Page Setup Manager”. (Note: If a dialog box labeled “Revision Control for single Parts” appears, ignore it for now. Turn it off with the Cancel button. This ProSteel 3D feature is not covered in this training manual)
2. You will now see the AutoCAD 2008 “Page Setup Manager” manager, and the browser window within it may have two Current Page Setups listed. They should be “Layout1” and “Layout2”. (These are the 2 default Page Layouts supplied by default by AutoCAD on any new drawing)
3. Highlight the “Layout1” page setup and then click the Modify button. (Note: The page setup manager dialog box was new to AutoCAD 2005, and therefore appears in AutoCAD 2006 as well. If you are using an older version of AutoCAD, then step 2 of this exercise is not applicable.)

Objectives
4. You are now presented with the “Page Setup – Layout1” dialog box, and this will be used to setup the Paperspace Layout ready for Viewports, Views, and for Plotting purposes.
5. Insert the values according to the illustration shown below:
Our plot device in this case will be a virtual printer, the DWF6 ePlot printer. This virtual device will produce DWF plot files, similar in nature to Adobe PDF files, but purposely built for AutoCAD drawings. DWF files can be viewed using the new “Autodesk Design Review”, which can be downloaded free from the Autodesk website. The viewer will more than likely already be installed on your computer if you are using AutoCAD 2007 or latter. The ISO full bleed A1 paper size will allow us to plot and draw almost to the edges of the paper. A1 paper is plotted to an A1 device at full size, hence the 1:1 Plot Scale. And the plot area is set to Layout, because we are dealing with a Paperspace Layout. We will for this exercise use a Monochrome .ctb file as shown, however at some stage you may want to consider using your own .ctb file for Pen Setting purposes (pen settings or lineweights on the paper plot)
6. When you OK the dialog box, and then close the Page Setup Manager, you should then see a Paperspace Layout that looks something like the following:
288 Copyright © 2009 Bentley Systems, Incorporated

Objectives
7. Now repeat parts 1 to 3 of this exercise, but this time for Layout 2. You should then end up with 2 paperspace layouts named Layout 1, and Layout 2, and the 2 layouts should look identical.
8. Now left click the tab “Layout 1” to make that Paperspace Layout the active one, then right click the Layout 1 tab, and from the context sensitive menu provided, choose “Rename”. Please now rename the Paperspace Layout as S01 (for Structural Sheet number 1). Do the same for Layout 2, but rename it as S02.
9. The small “Viewports” that have been automatically created on each Paperspace Layout should ideally be on an independent layer. Now create a new AutoCAD Layer called VPORTS, and ensure that the viewports sit on that Layer. You could possibly use the AutoCAD Properties dialog box to move the viewports onto the VPORTS Layer. You should also turn that layer off from printing by forcing a slash over the printer icon located to the right of the VPORTS layer, inside the “Layer Properties Manager” dialog box.
10. We will now create a third Paperspace Layout, similar to the other two. Left click the layout tab called S02 to make it active, then right cl ick the S02 tab, and from the context sensi tive menu provided, choose “Move or Copy”.
11. The AutoCAD “Move or Copy” dialog box appears as shown above. Ensure that the S02 listing is highlighted in the Before layout area of the box.

12. Tick the Create a Copy cell at bottom left, then close the dialog box with the OK button. A new layout tab is now created, and called S02 (2). You should now rename that layout tab as S03 (refer to part 3 of this exercise). Now left click the layout tab called S03, then right click the S03 tab, and from the context sensitive menu provided, choose “Move or Copy” again. This time left click the words “(move to end)” inside the dialog box provided to highlight them, click the OK button in the dialog box, and your layout tabs should now be ordered in sequence. This makes for good CAD management inside your AutoCAD drawing file. You should now have three Paperspace Layouts that look similar, and that have the same PAGE SETUP settings.

Exercise 20-2 Adding Viewports to Paperspace Layouts In any paperspace layout, you can create, position and size viewports. Viewports display a drawing's model space objects, that is, the objects you created on the Model tab. Each viewport can display the model space objects from a specific location, and at a speci fied scale. We will now add more viewports to each of our paperspace layouts, and we will set the viewports such that they look at our ProConcrete 3D model from different viewpoints or locations.
1. Make layout tab S01 your current Layout by left clicking it. You can zoom and pan around your layout just like you can down in modelspace.
2. Click the only viewport shown on Layout S01 once, to invoke the AutoCAD “Grips” for this object. There should be one grip at each corner of the viewport. Using the Grips, resize the Viewport so that it is just smaller than ¼ the size of the A1 Paperspace Layout.
3. Now double click inside the viewport, such that the viewport allows you to work through it and on the model down in modelspace. Now perform a ZOOM Extents to fill the viewport with your 3D model. Next, double left click on the paper (outside the viewport), to allow you to work back up in Paperspace.
4. Now use the AutoCAD COPY command to copy the viewport 3 more times onto the same paperspace layout. You should now have a paperspace Layout that looks like this:
Ensure that enough room is left outside your viewports so that you could insert a company border and titleblock onto the surface of the Paperspace Layout, should you need one. We will not use a border or titleblock in our case.

5. We now need to set each of the 4 viewports on layout S01 to look at our 3D model from different directions. The ProSteel 3D Viewtools toolbar allows us to look at our model from several predetermined viewpoints, by using the Isometric Overview tool.
or Hold down the Isometric Overview 1 button to find 4 additional Isometric Overviews. Or use the ProSteel 3D Overview toolbar. There are 5 predetermined viewpoints available. Double click into each of the 4 viewports (one viewport at a time) and use the Isometric Overview pulldown to recall a different view. An automatic zoom extents is performed when using the Isometric Overview tool.
6. When finished with all 4 viewports, double click back on to the surface of the paperspace layout. You might now like to add some text headings under each of the viewports describing the views. Use an appropriate text style, and text size (you probably have company standards for this). The text headings should also be on their own individual layer. If necessary create a new AutoCAD Layer for these text labels. When this is done, you should now have a layout that looks something like this:
Note: These rectangles are indicative of the viewports that sit on your layouts. The linework is displayed, but will not plot, if you have set your layer for viewports to not plot. (See Exercise 30-1, Step 5) We have not yet set these isometric views to any specific scale. We will do this in exercise 30-3.
7. We now need to set the viewports on layout tabs S02 and S03. S01 represents our Isometric Overviews drawing. S02 will be for Plan Views and some Perspective Views. 292 Copyright Š 2009 Bentley Systems, Incorporated

8. Make layout S02 your active layout by a left click on the layout tab. Resize the existing viewport, then copy it once, in a similar way as we did in parts 1 and 2 of this exercise, such that we will be able to have an overall plan of our building, plus a perspective view. Leave enough room for 2 further plans, and 1 extra perspective views (see the diagram on the next page). We will end up with a total of 5 viewports on this layout.
9.
Double click through and into the top viewport and invoke the ProSteel 3D Plan View command. It is on the ProSteel 3D Viewtools toolbar, and when used, you should see an overall plan view of your ProSteel 3D model . We will set a scale for this view later.
10. Now double click through the second viewport, and invoke the AutoCAD ORBIT command. As you already have an isometric view of your model here, just right click to use the Orbit context sensitive menu, and choose the Perspective command from the Projection flyout. This will now give you a perspective view of your model.
11. Now double click back up onto the paper, and add text headings as you did in part 2 of this exercise. (You could cut and paste headings from layout S02, and then edit them to the correct wording) You should now have a layout that looks something like this:
We have not yet set the plan view to any specific scale. We will do this in exercise 30-3
12. Now make layout S03 your active layout by a left click on the layout tab. Resize the existing viewport, then copy it, as we did in parts 1 and 2 of this exercise, such that we will be able to have a front view of our building, plus a side view. Leave enough room for

2 further elevations, and 1 extra detail (see the diagram on the next page) We will end up with a total of 6 viewports on this layout.
13.
Double click through and into the top left viewport and invoke the ProSteel 3D Select View command. It is on the ProSteel 3D Viewtools toolbar. Choose the Zone1Elevation GridX1 view from the list of views in the ProSteel 3D Select View dialog box. You will now see the clipped view in your viewport, you can zoom to fill the viewport if you wish.
14. In the second viewport on your layout, invoke the Select View command and choose the Zone1-Elevation GridYC view.
15. Now copy the second viewport containing the view of the Zone1-Eelevation GridYC frame to the right side of your layout. Resize this viewport so that it is much smaller. Double click into this new viewport, and zoom in to the Gridline 2, column to footing pad area at the ground level. This will form the basis for our footing detail.
16. Now add some text headings as you did in the last part of this exercise, and you should now have a layout that looks something like this:
We have not yet set the views to any specific scale. We will do this in Exercise 30-3.

Exercise 20-3 Adjusting Viewports to Appropriate Scale Paperspace viewports can be set so that they display your model at an appropriate drawing scale. Although the ProSteel 3D model has been drawn to full size, a scale of 1:1, the model can be set to appear at say a scale of 1:100, or 1:50 for all plan and elevation type views, and possibly 1:10 or 1:20 for detail views. The viewports can then be locked so that the views cannot accidentally be zoomed out of scale, and the viewports can also be used to control the plotted appearance of the view. For instance views can remain as wire frame views, can be plotted with hidden lines removed, or possibly as shaded views. To enable us to set views to correct scales, we will need to use the AutoCAD “VIEWPORTS” toolbar:
This is the AutoCAD VIEWPORTS toolbar. Please ensure this toolbar is displayed as a horizontal toolbar. The drop-down list at the right hand side of the toolbar has a list of common drawing scales, metric and imperial. These scales will be used to set our viewports. If an appropriate scale cannot be found on the list, you can swipe the scale displayed at the top of the list, and you can then type your required scale.
1. Make layout tab S01 your current Layout by left clicking i t. Then double click into the top left viewport on this layout, to make that viewport your active one. Now from the dropdown list of scales on the Viewports Toolbar, select 1:100. This isometric view of your model is now displayed at exactly1:100. You could also pan your view so that it sits in the middle of your viewport. You need to avoid zooming while inside the viewport, otherwise you could put the view out of scale. To ensure that the viewport is not put out of scale, you need to double click back up onto paperspace, now left click the top left viewport border once to invoke its grips, (click the viewport edge, not the empty space inside the viewport). Now right click to invoke the context sensitive right click menu and then choose Properties from the menu. You will now see the AutoCAD 2006 Properties dialog box. (The Properties dialog box is shown on the next page). The AutoCAD 2006 Properties dialog box, like many others in AutoCAD 2006, is resizable in both directions. The Properties dialog tel ls us many things about AutoCAD objects that we are interested in. We can also change the Properties of objects from within this dialog box, such as the Layer the object is drawn on, the color it was drawn with, and we can even change the geometric values of many objects from here. We are going to change the locking value, and plotting properties of our viewport from here. Under the “Misc” area of the Properties dialog box, find “Display Locked”. If you click into the cell just to the right of “Display Locked”, you will have access to a drop

down list, and you will be able to change the value from NO to YES. A value of YES will lock the viewport so that it cannot be put out of scale. If you now double click back into the viewport, and apply a zoom while the viewport is locked, you will see that paperspace zooms along with modelspace. The viewport cannot be put out of scale.
From the same Properties dialog box, (and while still enquiring into the properties of the top left viewport) set the SHADE PLOT property to HIDDEN. This now means that although the viewport displays as wireframe on the computer monitor, the viewport will actually plot as hidden lines removed. Click the dialog off with X (top of dialog labeled heading) to save property changes.
2. Repeat step one of the exercise for the other 3 viewports on Layout S01. You should end up with 4 viewports set to a viewport scale of 1:100. All 4 viewports will be locked, but only set the top 2 viewports such that Shade Plot is HIDDEN. Leave the bottom two viewports set to Shade Plot WIREFRAME. Viewports can be resized, even after locking. Resizing can be done by invoking the grips for the viewport, and then using the grips to stretch the viewport bigger or smaller. You may need to do this after you have set the viewport scale to 1:100 so that you can see all of your isometric view. You may also need to move the text headings to a better location if needed. If you were to now plot the layout S01, it may look something like this.

3. Now make Layout S02 the current Layout. Double click into your only viewport showing a plan view of your ProSteel 3D model, and as you did in part 2 of this exercise, set the viewport scale to 1:100. You may need to resize the viewport. Allow enough room outside the plan for dimensions to be added at a later stage. Do not lock the viewport just yet. Now copy this viewport across to the right 2 more times, and also 1 extra time to the bottom right of your sheet. Ensure that ORTHO is on so the viewports line up. We will use these additional viewports for plans at different levels of the building. Also copy the viewport with the perspective view one more time. You should now have 6 viewports on Layout S02.
4. Double click into the top left viewport to make it current, then from the ProSteel 3D Select View dialog box, make the view Zone1_Plan Level 0 current. You will now see a plan at Ground Level within this viewport. Ensure that this viewport is still scaled to 1:100, and i f not then adjust accordingly. You should now LOCK this viewport, and set Shade Plot to HIDDEN, as was done in part 2 of this exercise.
5. Repeat Step 4 three more times. First, for the top middle viewport (set this view to Zone1_Plan Level 1). Second, for the top right viewport (set this view to Zone1_Plan Level 2) and third, for the top right viewport (set this view to Zone1_Plan Level 3). Ensure that these 4 viewport scales are set to 1:100, that Shade Plot is set to HIDDEN, and that they are now all locked.
6. Double click through bottom middle viewport, invoke the AutoCAD ORBIT command, and change the second perspective view so that you look at your Prosteel 3D model from a different vantage point. Perspective views of models cannot have a fixed viewport scale, so we can only zoom into each of the 2 perspective views to make them larger or smaller. When you have done this, LOCK both perspective viewports, and then set the Shade Plot for both of these 2 views to RENDERED. This will allow the viewports to plot as SHADED / RENDERED views.

Now add more text headings to the Layout, or copy and modify the existing text headings on the layout, so that you end up with view names for Ground Level, Level 1, Level 2, Level 3, and Perspective View 1 and Perspective View 2. Ensure the text labels are on a suitable layer. If you were now to plot this drawing, you would end up with 4 plans views with hidden line removed, and 2 different perspective and shaded views. The plotted example is shown below.
7. Use similar techniques shown in all parts of this exercise to alter layout S03, so that it has 6 viewports showing 1:100 elevations of the ProConcrete 3D model, and 2 viewports showing 1:20 details of the circular column at Gridline C. A plotted example of layout S03 is shown below.

ProConcrete 3D Annotation in Model Space
Overview In this chapter, you will learn how to add ProSteel Annotation to your Plan Views and Elevations.
Objectives In this chapter, you will: Learn how to add ProSteel Annotation to your Plan Views and Elevations This manual presents fundamental concepts you need to know about the modelling process in ProConcrete 3D.

Exercise 21-1 Adding Position Flags to Plan Views The majority of annotation on typical consulting engineers drawings consists of labels indicating structural member sizes, and possibly mark numbers as well. Mark numbers as we know them are called Position numbers inside ProSteel 3D and ProConcrete 3D. Position numbers can be generated in ProConcrete 3D automatically using the “Positioning” command. For this exercise, we will not be adding position numbers to our model components. This should have been done in an earlier chapter. (Chapter 17 of the ProConcrete 3D training manual entitled POSITIONING) However, the ProSteel/ProConcrete 3D Positioning dialog box allows us to manually add Position Flags (leader lines with member sizes attached) to our model views.
1.
While in drawing 7092Model1, from model space only, view your ProSteel 3D model in plan view at Level 1. Use the ProSteel Select View command to do this, select the view entitled Zone1_Plan Level1, and perform a zoom extents if necessary such that you see all of your model.
2.
Since the viewports on layout S02 (of drawing S001) display the plan views at a scale of 1:100, we can now temporarily set the global scale for our model to this scale by using the ProSteel 3D Scale command. When you left click this button, you will be asked at the command line to enter a new ProSteel 3D default scale. Type 100. This will ensure that our Position Flags are sized for 1:100 views.
3.
Now invoke the ProSteel 3D Positioning dialog box, by clicking the POSITIONING button on the ProSteel 3D Edit toolbar. There are many tabs, buttons and cells on this dialog box that are used when Positioning concrete or steel members, and also producing shop detail drawings. Since we are producing consulting engineer style drawings with manual position f lags, we only at this stage need to ensure that the Apply Style area of the dialog box is set appropriately. Notice also that the Scale 1:x is set at 100, due to the ProSteel 3D Scale command set previously.
4. We now need to define the style of f lag to be used when manually inserting position flags. In this case we will create a new Positioning Style to use called “PC3D Cons-Label”.

5.
Click the STYLE button on the Sort tab of the ProSteel 3D Positionf lags and Positioning dialog box, and then on the resulting dialog box, Enter the Name of the new Positionf lag Style as PC3D Cons-Label. Click the OK button on this dialog box, and the new style is added to the SORT tab.
6. Now that we have a new Positionflag style, we need to define it so that it shows the correct type of information. Go to the Layout tab of the ProSteel 3D Positionf lag and Positioning dialog box, and choose PC3D Cons-Label from the Style dropdown list.
7.

Now click the “Enables setting of the Position flag Style” button. It is to the right of the label, Created Geometry.

8. You will need to fill out the values in the resultant Posflag Definition” dialog box, as shown below. This will provide you with Position Flags that include member sizes (Element Name), a text size of 2.5mm (x 100), and arrows on the ends of leader lines.
9. Click the OK button at bottom left when you have defined the new style. On the SORT tab, make the new style (PC3D Cons-Label) the current one. Note: It is worth considering saving new Position Flag styles for use in future projects. You can save new styles, & load existing styles using the two buttons shown above (from the Layout tab). The styles are stored in the following folder (or similar): C:\Program Files\Bentley\ProStructure\V8i\AutoCAD 2008\Localised\English\Styles\PosflagStyles\Metric
10.
You are now back at the ProSteel 3D Positionflags and Positioning dialog box. Go to the INSERT tab of this box, and click the “Sets the Default Styles to Attach Distinct Position Flags” button. This feature will be used to tell ProSteel 3D which positionflag styles to use for various parts of your model. On the resul ting dialog box, fill out the values as shown below.
Note: Normally, only the “Single Part” default style setting needs to be set for concrete parts. The Group, Mainpart, Subpart, Bolts, Short Position and Mounting default style settings are generally used in ProSteel 3D only for steel parts and groups.
11. Click the OK button at bottom left when finished. 12.
Back on the ProSteel 3D Positionflags and Positioning dialog box, click the “Attach Position Flag to Single Part” button to add the first Position Flag to your model , at Level 1. At the command line, you are asked to Select the Part to be Positioned. Left click any part of one of the beams at Gridline C, as you move your cursor away from the beam, and providing ORTHO is not on, you will be able to place the position f lag such that the member is annotated. Repeat this procedure for all of the beams at Level 1, and you should now have a plan view that looks something like this:
304 Copyright © 2009 Bentley Systems, Incorporated

Objectives
Note: You may need to temporarily change the position flag style to allow for vertical alignment of position f lags, rather than for horizontal alignment. This works well for the beams at gridlines 1,2 & 3 on this model. You may want to use cycling techniques when picking objects that you wish to attach a position flag to, as many beams, construction lines and Workframes lines are drawn on top of each other. If you hold down the CTRL key when selecting an object, you are then able to cycle between them until the correct one is found.
13. You may now like to add some position flags to the columns and beams that appear on your model at Gridline C. While in Modelspace only, make the Gridline C view your current view (use the select view tool), then add position flags just as you have done for the previous parts of this exercise. You should now annotate this view so that it looks something like this:

Objectives
Note: After placing Pos Flags, you can resize or re-locate them (including the arrow ends) using standard AutoCAD grip editing techniques. Note: If you are not happy with the wording that appears in the text portion of the placed Position Flags, then you are able to edit it manually. Double click the flag, and the “Pos. Flag Properties” dialog box appears with all of the values for the current f lag appearing in the dialog box.
14. From the DATA tab of the dialog box, you are able to edit the Name value as required. Finish with the OK button, and the flag is adjusted accordingly. Additional values, such as the Pos No., can be added to existing pos f lags by ticking on appropriate settings from the Layout tab of the Pos. Flag Properties dialog box. This is because the flag holds all available information about the object it was attached to.
15. If you now view your overall model from an isometric viewpoint, you may notice that all of the position flags placed so far are visible in the model. All of the flags have been placed on a ProSteel layer called PS_POS. This is OK from a normal layer management point of view, but ideally we need position f lags placed on different layers, so that we can control the visibility of the f lags at different areas of the model, through the various paperspace viewports. We will learn how to do this in Exercise 21-2.

Visibility of Position Flags at plotting time
Visibility of Position Flags at plotting time Placement of Position Flags needs to be considered for the final outcome of your drawing files, the plotted Paperspace Layouts. Position Flags need to be on layers that can be controlled such that the flags are visible in the relevant paperspace viewports, and invisible through non-relevant viewports. If you now look at the layout S02, you will see that the flags are visible through the Level 1 viewport (the top middle viewport of your page), and that the text of the flags, when measured on paperspace appears at 3mm high. The flags are also visible in the perpective view viewports. But if you now plot paperspace layout S02 (just try a full preview at this stage), you will see that the Position Flags do not now show on the paper. This is because our viewports are set to a Shade Plot of HIDDEN, and by default, ProSteel does not display Position Flags on plotted HIDDEN views. We need to force ProSteel 3D to plot the flags. From the ProSteel 3D options dialog box, we can turn on the visibility of Position Flags, and other 2D objects, for plotting purposes. Go to the Display tab of the dialog box, and change the settings to the values shown below:
As the paperspace layouts have viewports on them, it is essential that Full Support is turned on. You may need to turn this off though when continuing to model your project, and back on again when it comes to plotting. Position Flags at Shade needs to be on, and Workframe at Shade needs to be on if you want plotted workframe lines. Note: After you change these values, click the OK button in the dialog box in order to have ProSteel / ProConcrete retain the changes. Depending on your PC, you may need to close ProSteel down, then restart again to force the changes to occur.

Visibility of Position Flags at plotting time
Exercise 21-2 Adding Position Flags to Elevational Views As you have seen in the previous exercise, when adding Position Flags to your model, while in model space only, all f lags are created on the layer PS_POS. This will not give us enough control over visibility of f lags through several paperspace viewports. So we will now add Position Flags while reaching through paperspace viewports. This will allow the Position Flags to be created on unique layers, specifically matched to each paperspace viewport. Note: Each viewport has a unique identification number. Use the AutoCAD LIST command to display information about a particular viewport, and you will see that there is a term called HANDLE, with a relevant handle code. Every object drawn in AutoCAD has a unique handle code. ProSteel 3D makes use of this handle code for a viewport, and creates a unique layer which has a name similar to the viewport handle code.
1. Make paperspace layout S03 your current layout, and ensure that you are in paperspace. Now zoom closer to the top left viewport, the one showing an elevation at gridline 1 of your ProSteel 3D model, such that the viewport almost fills the drawing area. Now double click over the viewport. This will “open” the viewport so that you can draw through it. This is something that we would not normally do in a consultants office, as we now have a smaller drawing area, or viewport, to draw through. But because we have previously LOCKED the viewport, we will not accidentally put it out of its zoomed scale of 1:100. When we perform a zoom or pan inside this viewport, paperspace zooms and pans with the viewport.
2. You can now attach Position Flags to all of the main structural members inside this viewport, just as you did in the previous exercise. However, to force the Pos Flag onto s unique layer that suits this viewport, create a new AutoCAD layer, name it Pos-Elev-Grid1, and make this layer current. Ensure that the Layer colour is 8 (same as for PS-POS layer). Note: When placing the f lags, ensure that you select this new Layer from the pulldown list on the INSERT tab of the “ProSteel 3D Positionf lags and Positioning” dialog box. If you do not set this layer, you will have to move the new flags onto the correct layer after they have been placed, using normal AutoCAD techniques. When complete, your annotated view should look something like this:

Visibility of Position Flags at plotting time
3. Repeat part 1 one this exercise, but for the two other viewports that have the Gridline 2 and Gridline 3 views. Ensure that you manually create new layers suitable for Position Flag placement within those viewports. The new layer names should be Pos-Elev-Grid2 and Pos-Elev-Grid3. Each time you double click into a viewport to make it active, the Position Flags attached inside the viewport will be on unique layers related to the viewport, provided you set the Layers dropdown list within the INSERT tab of the “ProSteel 3D Positionflags and Positioning” dialog box, when placing the f lags. Note: The Position Flags on different layers gives you more flexibility over the way that you can plot your ProSteel 3D model. Each time you add Position Flags you also need to think about the Style for the flag. Should the text be horizontal or vertical? Does the ProSteel 3D Scale need to be changed to suit differently scaled viewports? Your S03 drawing should now look something like this:
4. Create new Layers for all viewports on Sheets S02 and S03 for all plan views and elevational views. Then add Pos. Flags to al l of those views, in a similar manner to what was done at Steps 1 and 2. Move the flags that have already been placed on Layer PS_POS (as was done Exercise 21-1) to more suitable layers using AutoCAD property management techniques.
5. We do not want any of the current Position Flags to show through the Isometric or Perspective viewports on layouts S01 and S02. Notice that if you make S01 your current layout, that you can see all of the Position Flags currently drawn for the whole model, in all of the viewports. To freeze the layers containing the flags, double click into a viewport, then invoke the AutoCAD “Layer Properties Manager” dialog box, (the LAYER command) then from the right side of the layer dialog box, under the “Current VP Freeze” heading, freeze off al l of the layers that contain Position Flags. (You may need to repeat this procedure at a later stage if you add more flags through new viewports). Repeat this procedure for all of the viewports on layout S01.

Visibility of Position Flags at plotting time
Note for all plotted layouts: The ProSteel 3D Workframe Lines can be plotted on all sheets. If you do not want the Workframe lines showing in the Isometric and Perspective viewports, then the layers PS_FRAME and PS_OBJECT need to be frozen off in those current viewports only. Some consulting engineers prefer to draw a Grid System that suits their building on separate layers, rather than use the ProSteel 3D Workframe and its inherent grid bubbles. You may wish to consider this. Note also that Grid System lines and dimension linework could in fact be added up in paperspace. Your current company pen settings (or .CTB files) may need to be considered for plotting purposes. You may need to create a specific .CTB file for ProSteel models that suits your company style of plotting.
7. Save your 3D model to disk after every major step in your modeling process. This will avoid loss of data in the event of a crash.
8. A major consideration when plotting ProConcrete 3D paperspace drawings is linetypes. Linetypes in ProSteel 3D are as for linetypes in AutoCAD. There are two components that need to be dealt with when considering linetypes. They are, hidden linetype generation, and linetype scale.
9. For linetype scaling on our current model, do the following. Set the AutoCAD LTSCALE command to 1. Set the AutoCAD PSLTSCALE command also to 1. These settings will then force your AutoCAD viewports to control how linetype scaling is displayed. If a viewport display scale is set to 1:100, then the settings above will make your hidden linetypes appear on the paper to suit a 1:100 scale. If a viewport is set 1:50, then it will plot accordingly. But because LTSCALE is set to 1, linetypes will not be easy to see in modelspace. (Note: The settings noted here are used only when you have drawings that contain multiple paperspace layouts that include many viewports with various display scales. For ProConcrete 3D 2D detail drawings that are created automatically in modelspace, LTSCALE is automatically set by the program.)
10. Hidden linetype generation needs to be turned on when creating and plotting paperspace layouts such as S02 and S03. This is so that edges of concrete edges behind or under other concrete objects can be seen. This would be the case for beams under slabs, and slabs behind beams etc.
11. To turn on hidden linetype generation, go to the AutoCAD OPTIONS dialog box, and select the User Preferences tab. Click the button at bottom left labeled HIDDEN LINE SETTINGS. You will then see the Hidden Line Settings dialog box. Fill in the values in the box as shown below. Then click the OK button, apply and close the Options dialog box.

Note: When plotting layout S01, we do not want hidden lines to display. You will need to set the Obscured Lines / Linetype dropdown list in the dialog box shown above back to OFF.
12. When you have set out your layouts as explained through the last two chapters, click onto each tab and perform a zoom all. This will fill your screen with an overall zoom that layout. Finally click back to modelspace, and then select the Isometric Overview 1 button. This will provide you with a zoomed extents isometric view. It is a good idea that when saving and then closing 3D model drawings, that you exit the drawing from modelspace.
13. Save your current drawing to hard disk once again.

Exercise 22-1Adding Position Flags to Isometric Views Generally speaking, in countries such as New Zealand and Australia, consulting engineers have placed all annotation on their AutoCAD drawings down in modelspace. By “all annotation”, we mean all dimensions, all gridlines, all detail balls, section marks and text such as member sizes, text headings and leader lines with attached notes. The reason for all this annotated modeling is primarily because in the building design industry, we tend to share drawings. For example the Structural Consultant may use the Architects CAD drawings to construct his documents, and the Electrical designers and HVAC designers may in turn use the Consulting Engineers drawings to construct their drawings. Because not all CAD users have AutoCAD, (some may have other CAD software), and because most of the better CAD programs allow you to open or insert an AutoCAD drawing, anything that is not drawn in Modelspace in the AutoCAD drawing, may not be visible in the other CAD program. Paperspace is a unique concept which is part of Autodesks AutoCAD based products only, and as such, normally only drawing borders and titleblocks are drawn on Paperspace. This attitude towards what is drawn on Modelspace, and what is drawn in Paperspace is beginning to change though, as more and more people are moving to drawing 3D models to present and plot these models efficiently, we need to utilize the power of Paperspace and its inherent Viewports. We will now add Position Flags to our isometric views, and since the f lags need to be aligned to the paper, and not the various elevations of the model, we will place the flags in Paperspace.
1.
From your drawing 7092Model1, make layout S01 the current layout, and since we will be placing Position Flags on Paperspace, set the ProSteel 3D Scale command to 1:1. Paperspace layouts are almost always plotted at 1:1 scale, and objects drawn on paperspace, such as text headings and titleblocks, are of course drawn at full size, 1:1.
2.
Now make the top left viewport current, by double clicking inside the viewport. We can now draw down on the model, while reaching through the viewport. Now invoke the ProSteel 3D Positioning dialog box, by clicking the POSITIONING button on the ProSteel 3D Edit toolbar.
3. We can leave the settings for the ProSteel 3D Position flags and Positioning dialog box. In the bottom left corner of INSERT tab of the dialog box, the “In Paperspace” option needs to be ticked on. The Scale on this tab should read 1, because we set the ProSteel 3D Scale was also set to 1. (Also check that f lags are set to be inserted horizontally, rather than vertically.) The “In Paperspace” option will ensure that even though we select objects within the modelspace viewport to receive flags, the Position Flags will be placed in Paperspace, and not Modelspace. The “Scale 1: x “ area of the dialog box becomes displays 1, because all paperspace objects are placed at 1:1 anyway, and the positioning STYLE of course controls the appearance and size of the flag.

Objectives
4. Now place Position Flags as you did in the previous chapter, to all main members on the model, and the flags will actually end up on Paperspace, and are aligned with the Paper. You can check this after you have placed the f lags, by trying to click them, or checking their properties while remaining in modelspace. You will see that you cannot select the flag until such time as you are up in paperspace. The flags that are created while reaching through this viewport, are automatically placed on a unique layer, related to the viewport handle, just as was done in the last chapter.
5. Repeat placing flags in the other three viewports on this layout. Of course the f lags will actually appear in Paperspace because of the Positioning dialog box settings. If you were to then plot your layout S01 after placing flags, it might look like this:
6. When placing position flags, you are asked at the AutoCAD command line to “select Element to be Positioned”. In order to select an element, you must pick its edge. If you are not happy with the location of the arrowhead after placing a flag, you can use AutoCAD grip editing techniques to literally relocate the arrowhead. This will allow you to point the arrowhead away from an object edge. You may wish to this for a position flag that points at a slab. Note: You will need to be in Paperspace to grip edit the flags placed in this exercise.
7. When reaching through viewports to place flags in paperspace, it is a good practice to have your modelspace UCS set to WORLD UCS. You can easily achieve this by the use of the Overview 1 button. If your UCS is not set to world, your f lag may not be able to be positioned accurately. Save your drawing to hard disk again

Editing existing Position Flags
Editing existing Position Flags With most modern versions of AutoCAD, if you double click an AutoCAD object, you will be presented with some form of dialog box, e.g., Properties dialog, Mtext editor, Reference editor etc. The same thing applies with ProConcrete 3D. Double click a ProConcrete / ProSteel 3D object and you will see a ProConcrete / ProSteel 3D Shape Properties dialog box. But double click a Position Flag, which is a 2D object, and you will see the Pos. Flag Properties dialog box. As is shown below for a typical Position Flag, the dialog box has four tabs. The STYLE tab allows you to control the appearance of the flag. The LAYOUT tab allows you to control what text data appears on the flag, also text sizes, and flag component colours. The DATA tab allows you to edit the text on the flag. The VALUES tab displays the dimensions of the object that the flag points to.
Note that the dialog box tabs shown above have plenty of dropdown l ists and buttons for setting values. Please experiment with the settings in the dialog box to determine a Position Flag that suits your style of Consulting Engineers drawings. You may be able to match your current company standards by experimenting with Position Flags.

Note: Different position flag STYLES can be saved and recalled as style templates by using the TEMPLATE button. It is better practice to place correct styles when placing flags, then to change the flag information at a later stage of your modeling.
