Assignment 1 : Multiview Drawing Narrative : The first assignment was to create simple objects with simple geometry at different positions and angles. Strength : The biggest positive thing was the use of make2D. We were able to create hatches, dashes and control the lightweights at the way we want.

Weakness : All the hatches on the left hand sides here are white. It would be better to understand the surfaces with different colors (grey, dark grey) instead. Opportunity : Since this’s the first assignment, we started with simple objects. I could try different complex objects next time for this assignment. Risk : The more complex it is, the more I have to be more careful for my lightweights, positions, dashes so that it could be seen clearly.

Assignment 2 : Planar Objects and Folding Narrative : This assignment is the lesson of folding. There were two methods of folding for this one: folding the polygonal shape a minimum of 4 times and combining at least six 4-sides polygons at different angles so that it will have the concept of folding. I chose to go with the first method to go with this project.

Folding steps
Step 1 : create a polygonal shape
Step 5 : 4th folding
Step 2 : 1st folding
Step 3 : 2nd folding
Step 6 : 5th folding
Step 4 : 3rd folding
Step 7 : final folding

Section
Strength : With the command “unrollsrf,” we were able to create a real physical model after this assignment.
Weakness : The section cut was not in the perfect cut. There’s a small piece which does not tell anything for the cut. Opportunity : It would be possible to try folding the curved objects and get a big folded, curved object through this method of folding. Risk : Even though it’s easy to fold a planar one, a curved one would be so difficult.

Assignment 3 : Boolean
Narrative : This project is basically using the boolean commands to cut away the objects you don’t want by using an addition object or objects. For example, if a rectangle and a circle are intersected in a way, we can use the boolean commands, such as boolean difference, boolean intersection, boolean split to carve away the pieces of the intersection parts and one of the objects so that the other object still remain. Weakness : All the objects on the left side (the previous page) are not set in the same oriented view. Sometimes it would be a little bit difficult for others to understand the views.

Steps
Step 1 : create a simple object
result
Step 2 : use the cutting planes to cut the pieces
a cut object
Step 4 : put the blue-coloured object into the object and cut
Step 3 : put the two objects on the cut object
Final object
11
Strength : If we have the intersection of many objects, even 7 ~ 8, we can still cut away the pieces you don’t away by using the boolean commands and remain the pieces you like. We were able to create a physical object. The hatches on the left hand side are in different colors(dark grey, grey and white). Opportunity : It would be nice to try a curved object being cut inside the original object. Risk : I have to be very careful using the loft tool for the curved surface so that while I’m creating the physical model, it’d be easier.

Assignment 4 : Grafting
Step 1 : create a border between the two original given curve lines with the help of a box
14
Narrative : Two original nurbs surfaces were given. We here had a cha two quadrants are met. Here, we had to construct a new surface that is
Step 2 : Extract u & v lines on the original surfaces (which are the upper and bottom ones) and draw vertical lines between the u lines and v lines.
Step 3 : Create
ance to learn the importance of tangency. Tangency is created when the touched to the original surfaces with tangency points.
nurbs from tangents
Step 4 : create a new srf by using the networksrf command
Step 5 : final result surface
15
SD Strength : We clearly understand how a curve line is created, which is one of the strength of using rhino. Opportunity : I could try to get more tangencies. Risk : Some tangency points are difficult to handle. Sometimes, some parts of the new surface go outside the original surface instead of stay perfectly between the two original surfaces.

Assignment 5 : Mashrabiya
Narrative : The Mashrabiya is a traditional element of Arabic Architecture. It’s a type of projected window enclosed with curved wood latticework, which usually is located on the second storey of a house. Since it gives us a good shade, privacy and sunlight, it’s often used in different places of Middle East. The materials such as wood, stone, metal and concrete were used to construct this type of window. Strength : After this assignment, we’re confident enough using different commands, such as networksrf, extrude curve, planarsrf, loft, sweep 1,2, and cap to create a curved surface. The level of rendering is getting better and better. Weakness : Since most of the parts of my structure are too sharp that it’d be scary and dangerous to others. Opportunity : I would try designing a smooth curved object instead of a sharp one. Risk : Still, there’d be some difficulties in creating a surface a curved one.

Pattern
Step 1 : create a circle in the center of the hexagon and draw additional circles along the arc of the original circle
18
Step 2 : the result of a total of six additional circles. Cut the white arcs which are outside of the hexagon.
Step 3 : the result final pattern
Step 5 : Then, I started to extrude the hexagon. Next, I closed up the bottom areas in order to make it closed polysurface.
Step 4 : Since the original pattern is in 2D, I started moving the red arc which is the nearest to the center of the pattern upwards and the other red arc which is the furthest away from the first red arc downwards. I used loft tool and get the first surfaces.
Step 6 : close up the upper areas so that I can get the whole closed polysurface.
