revit Furniture Modeling Guidelines

REVIT CATEGORY‐SPECIFIC GUIDELINES: FURNITURE SYSTEMS CATEGORY – FURNITURE SYSTEMS FAMILIES This document includes Autodesk specifications for the creation of Revit furniture systems families within the Revit Furniture systems category. By following the criteria suggested by both this guide and the Revit Model Content Style Guide, manufacturers and other content creators can create Furniture Systems families that adhere to Autodesk and Autodesk® Seek standards for Revit furniture systems families.

While this document contains specific system furniture family creation guidelines, it is not intended to provide specifications for every kind of system furniture family.

NAMING CONVENTIONS

Use the following guidelines when naming a new furniture systems family: Format: <Functional Type>‐ <Subtype>‐<Manufacturer>‐< Descriptor 1>‐<Descriptor2> Note: Refer to the Revit Master Part Type List (included in the download package) for information on approved Function Types and Subtypes.

Guidelines: • •

• • • • •

Create unique names for each furniture systems family.

Use natural language to name the family.

The family name should describe how the family is identified in the real world (for example, in catalogs or by manufacturer).

If possible, do not include the family category in the family name.

Capitalize the leading letters in each portion of the family name.

Keep file names as short as possible.

Family names must display in dialogs and in Type Selector.

If a type catalog is to be used with a family, name the type catalog (.txt file) with the same name as the family.

Do not use spaces between words in file names. To separate words within a syntax element (e.g., Manufacturer or Descriptor), use the underscore character (_).

SUBCATEGORIES

The furniture systems family template (Furniture Systems.rft) that is provided with the Revit software creates subcategories that you can use to control the display of furniture systems geometry (see Table 1 below).

You may also need to add subcategories. Table 2 below contains a list of Autodesk‐approved subcategories that you can add to furniture systems families. If you need to add subcategories that are not listed in Table 2, use the subcategory naming conventions and approval procedure described in the Revit Model Content Style Guide.

REFERENCE PLANES

Use reference planes in furniture system families to control dimensioning and snapping. A number of predefined and named reference planes are provided by the template that you use when you create a furniture system family.

Table 1 ‐ Reference Planes provided by the Furniture systems.rft template: Name

Center (Left/Right) Back Left Right Top Front

Is Reference (strength)

Center (Left/Right) (Strong) Back (Strong) Left (Strong) Right (Strong) Top (Strong) Front (Strong)

Defines Origin?

Yes Yes No No No No

If you need to add reference planes to a furniture systems family: • •

Any reference planes that you do not need to dimension or snap to, should be set to an Is Reference value of “Not a Reference.”

Keep reference plane naming consistent with those provided by the template.

PARAMETER USAGE

A list that contains all Autodesk‐approved parameters, Revit Master Parameter List.xls, is included in the download package. The Furniture systems section of this list contains all of the approved parameters for Furniture Systems families. In the following image a partial list of parameters is shown.

IMPORTANT: Refer to the Revit Master Parameter List for complete information.

In addition, the Revit Master Shared Parameter.txt file (including standard Autodesk shared parameters), is also included in the download package.

Make sure that any parameters that you add to a furniture systems family are included in the Revit Master Parameter List. If you need to create a new parameter that is not on the list, use the parameter naming conventions and approval procedure described in the Revit Model Content Style Guide.

The next sections of this topic describe some of the parameters that you need to consider or include when creating a manufactured furniture systems family for distribution.

RMCSG 2.1 — page 6

DIMENSION PARAMETERS The main dimensional parameters for furniture systems families are: • • •

Depth Height Width

The Depth, Height, and Width parameters determine the basic dimensions of furniture systems families.

CSI – OMNICLASS 1.0, MASTERFORMAT 2004, AND UNIFORMAT II PARAMETERS On Autodesk Seek, furniture systems families can be located by the appropriate CSI Omniclass 1.0, MasterFormat 2004, and UniFormat II codes. When sharing content with Autodesk Seek, indicate the code within the classification that should be assigned to the content.

Refer to the Revit Model Content Style Guide for information on including CSI Classification Codes with Revit families.

AUTODESK SEEK SPECIFIC SHARED PARAMETERS In addition to the system parameters, there are a number of shared parameters that can be added to furniture system families. Many of these parameters can be used to filter search results when searching for furniture system families on Autodesk Seek. It is recommended that you add these parameters to the manufactured system furniture families you intend to distribute on Autodesk Seek.

TYPES

NAMING CONVENTIONS All furniture systems families must include one predefined type. For families that create real‐world objects that are available in standard sizes, predefined types should be generated. Unless they represent nominal sizes, type names should include units or capacity, and include a unit indicator.

Format: For manufacturer‐specific furniture systems content: Use the manufacturer‐specific code for the furniture systems name and size: <manufacturer code> ‐ <size(optional)> Examples: FP34‐T FS‐1522 FT321 – 24” x 48” WS‐R – 24” x 60”

For generic furniture systems content: Unless there is a market‐specific reason to do otherwise, use this general format for furniture systems type names: <width> x <height> For imperial family types: In most cases, size should be expressed in inches. Use only one of the conventions below within a family and for related families.

For families with most sizes under 10’: XX” x YY” For families with most sizes over 10’:

XX’ – YY” x AA’ – BB”

For metric family types: For all types in metric families:

RMCSG 2.1 — page 8

XXXX x YYYYmm (or local metric unit indicator)

BEST PRACTICES

In addition to the guidelines published in the Revit Model Content Style Guide, use these furniture systems‐specific best practices:

T YPE C ATALOGS •

For furniture systems families that contain more than six types (sizes), create a type catalog.

P ERFORMANCE • • • •

Do not model hidden faces.

Only model simplified door and drawer pulls, do not model hinges and locksets Set door and drawer pulls to Medium and Fine Level of Detail Nesting geometry in furniture system families increases family file size and decreases performance. Use nesting only where appropriate (e.g., brackets) to allow itemization in schedules.

R ENDERING •

To ensure panels render with enough edge definition use a minimum gap of 1/8” between geometry edges.

RMCSG 2.1 — page 17

TESTING GUIDELINES

Use these furniture systems‐specific testing guidelines as a supplement to the general testing guidelines in the Revit Model Content Style Guide.

1.

Open the test project (included in the download package):

• To test an imperial family, open RAC_Furniture_Systems_Testing_Template_Imperial.rvt.

The test project includes sample elements that feature different styles, as well as Coarse, Fine, and Medium versions of certain views. Each of the views is set to the corresponding level of detail. The views are set this way so you can add an element to one view, and then open the two other views to inspect the element in the different levels of detail.

RMCSG 2.1 — page 18

2.

Load the furniture systems family in the test project:

If the family uses a type catalog, select and load all of the family types to verify that they load correctly.

In Typical Plan View ‐ Medium: 3.

4.

5.

6.

Using the default type (size) that displays in the Type Selector after you load the family, place a furniture systems component.

Test each furniture systems instance:

• Check the insertion point of the system furniture family.

• Verify proper masking of floor pattern.

• Verify that the system furniture family flips correctly.

Repeat Steps 3‐4, placing furniture systems components of the largest and smallest types.

NOTE: Depending on how many types are defined for the family, one of the types may be the same as the default type that you added in Step 3.

For all furniture systems in the test project:

• Verify system furniture family • Open the Coarse, Fine, and Medium plan views, and verify that each furniture systems plan representation displays correctly in the different levels of detail.

• Verify family in relation to other test content to ensure it displays properly in all plan views (typical plan views at all levels of detail and System Furniture views at all levels of detail).

• Dimension to all expected references and verify correct snapping behavior.

RMCSG 2.1 — page 19

In the remaining views (elevations, sections, 3D views, Preview): 7.

8.

Inspect the furniture systems in each view in Coarse, Medium, and Fine detail levels.

In 3D View, inspect the furniture systems geometry:

• Use the Orbit tool on the SteeringWheels to spin the walls and furniture systems, and verify that the geometry is constrained as expected. Check for unconnected geometry and/or plan representations that may be disconnected from the geometry.

•

Apply the following Model Graphics Style to the view, and verify that any materials applied to the furniture systems display correctly:

o

Hidden Line

o

Shading with Edges

•

Render the view and verify that any materials that are applied render correctly.

• Modify the material parameters, reapply the Hidden Line and Shading with Edges graphics styles, and re‐ render the view.

9. In the Elevation 1 view (all levels of detail), verify that the furniture systems geometry displays as expected.

10. In a Section view, verify that the furniture systems geometry displays as expected.

RMCSG 2.1 — page 20

11. Open the family in the family editor, and for the Preview view, verify that:

• Dimension and reference plane visibility is turned off.

• View Scale is set to 1 1/2” = 1’‐0” (for an imperial family) or 1:5 (for a metric family).

• Model Graphics Style is set to Shading with Edges.

• Detail Level is set to Fine.

•

The Preview view is set to the current view.

In the test project, in any view: 12. Create a furniture systems schedule and verify the furniture systems parameters (including any shared parameters that were applied) schedule correctly.

13. Select a furniture systems component in the test project, and:

• verify the furniture systems type properties.

• check all parameter names to ensure that they adhere to naming conventions and do not contain errors.
