WEEK 6 READING: SURFACES THAT CAN BE BUILT FROM PAPER IN ARCHITECTURAL GEOMETRY Question 1: What are the three elementary types of developable surfaces? Provide a brief description.

(Maximum 100 words) Cylinder surface - formed by a series of equal parallel lines (called rulings). To model this surface, parallel extrusion method is employed - a profile curve p is prescribed and extruded in direction r which produces a similar parallel p curve on the parallel edge of the section. In the case where r is 90 degrees to p, the section that p and r form is known as a normal section. Development of the surface means that the smooth cylinder surface are unfolded into a normal section showing a right angle between the section and rulings.

Cones - formed by central extrusion technique - points on profile curve p is connected to vertex v by many lines.

Tangent surfaces of space curves - Two consecutive vertices create determine the edges and three consecutive vertices determine a face plane. Polyhydral model is formed by edge lines and face plane.

Question 2: Why is the understanding of developable surface critical in the understanding of architectural geometry? Choose one precedent from Research/Precedents tab on LMS as an example for your discussion. (Maximum 100 words) Physically construct it and complex shape can be built up from the surfaces. Green house - by Plasma Studio, formed by a series of triangle.

TESTING - PANELLING 2D PATTERN

There are 9 different 2 dimensional patterns available on rhino. Three of them are shown.

2D Panelling, Pattern: Triangular

2D Panelling, Pattern: TriBasic

2D Panelling, Pattern: BoxX

TESTING - VARIABLE 2D PATTERN Pattern is created on the surface using “Panel Custom 2D” command. It is equally distributed on the surface.

Shape of customed pattern. Made out of “circle” and “polygon” commands. Choose “cen” from Osnap to help drawing the star from centre of the circle. “near” from Osnap helps the vertices to touch the circle circumference.

Variable pattern is created on the surface using “Panel Custom 2D Variable”command. The stars are dense on the top left. It starts spreading out and becoming smaller to the bottom right side.

Curve Attractor on Panel 2D and the surface to create the (middle right) pattern.

Another 2D custom variable pattern.

This time, instead of using curve attractor, point attractor is ultilised. A point is put on the centre. There is no relationship in an overall pattern. However,on the top and bottom left of the surface, the size of pattern increasing as it goes to the right.This pattern initially thought to be 2D pattern for the final design. Hence the grid points are ungrouped and some are deleted then the rest are grouped again to fit in the model.

3D PANEL TEST PROTOTYPE & TEMPLATE

Unroll and Tabs are on and printed to make model

Test model is folded. The template is printed on an A4 normal 80 gsm paper which is thin and easy to fold. The folding line shown in black in the front to help folding.

WEEK 7 READING: DIGITAL FABRICATION

Question 1: What is digital fabrication and how does it change the understanding of two dimensional representation? (Maximum 100 words) Digital fabrication is process that uses software (CAD/CAM prgram) to demonstrate a product (building) before they are built. This process not only enhances the accuracy and speed of the production but also arouses our creativity by testing our product in different shape, structure, colour and texture.

CAD program is easy to work with and is easily used to edit the two dimentional drawing effectively.

However, 2 dimentional representation does not vary although its perfection in term of accuracy by the change in technique. It is only 3 dimensional drawing that is distinctively changed.

Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding could be used in variety of scale. Being naturally deformed and inflected, folding provides a different perspective that we cannot experience when using digital fabrication.

EXPLORING 3D PANELLING

These are four 3D patterns using “Panel 3D Grid” Name of each pattern from left to right: Box3D, Partition, Wedge and Pyramid 1

FINAL DESIGN

The final design is done now is ready for making physical model

UNROLL TEMPLATE OF FINAL MODEL

Image shows 1 of the unroll and tabs with recess of 5 mm.

Unrol template are then put on 3 ivory cards. Use slide blade knife to trace the template and folding line on the card. This is because the card is thick tracing folding line help on folding later. Then cut the outline parts and fold.

PANELISED LANDSCAPE

Final model. The model flower is in the centre which is protected by wavy walls.

This shows a variation in the level of the technique from simpliest to a more complex one - from available 3D pattern on rhino to a custom pattern then custom variable pattern with different heights that are produced by offset points. Dark blue background gives a sense of model is floating and a different perspective to look at the model.

Close shot at the centre of the model which is placed on a white ivory card. Showing a slight spead out from the centre.

APPENDIX - ON RHINO

1. “Contour”and “loft” to make surface on a given terrain

2. Five seperate grid layouts for 5 different effects and patterns

3. Using “Panel 3D Grid” command to create 4 pryramis in the centre

4. These panels are customed separately which then combine to form a final model

11

5. Central part is finished. 4 piramids in the middle surrounded by self designing “piramids� that looks like they repel from the centre

7. Outer 3D wavy walls are done by varying height of offset point and 3D custom variable (3 modules are 3 panel on the left hand side)

12

6. 2D patterns that will be used in the final design

8. Nearly finished model

APPENDIX - MODEL MAKING

1. Equiment are prepared before cuting process (3 ivory cards, sliding blade knife, masking tape used when tracing the unroll and tabs template on ivory card)

2. A testing is proceeded on an A4 paper before making a real model

3. Tracing and cutting the “unroll� template with tabs on ivory cards

4. The next step of the process - folding

5. Arrange the fragments. One third of model is formed

6. Half of the process is done. The central part is sticked by double-sided tape

7. 3D and 2D fragments are added and sticked with the same type of tape in figure 6

8. The tap is not suitable for the surface as the tabs keep falling apart hence all purpose UHD glue is substituted. The sharp head of the toothpick is used to fill the small gaps with glue.
