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. The three elementry types of developable surfaces are: 1. Cylinders : Formed by extruded family of parallel lines along a profile curve. 2. Cones: Rulings from profile lines are extruded to one single point (I have chosen the pyramid for my model) 3. Tangent Surfaces of Space Curves: Formed from tangents that are aligned at different points along a space curve. The surfaces formed are called tangent surfaces.
1. Cylinder
2. Cone
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. The Green house by Plasma studio in Xi’an , China is made up of triangles that sit nicely in the landscape. Not only has the use of the developable surface ‘the cone’ informed the form of the building, it has also shaped the structure of the finer detailing such as cladding and glass panels. This example demonstrates the importance of using developable surfaces in architectural geometry to ensure design flexibility that can actually be constructed and fabricated.

PANELLING 2D PATTERN
2d Panelling, Pattern: Tribasic Works well. Surfaces join.
2d Panelling, Pattern: Anglebox Doesen’t work well. Surface edges don’t join since it isn’t a triangle based pattern.
2d Panelling, Pattern: Box Pattern. Same issue as above with the Anglebox pattern

VARIABLE 2D PATTERN
Variable 2D pattern using a diagonal attractor curve, distribution method mean.
Variable 2D pattern using diagonal attractor curve, distribution method rotate 45 and 90 degrees.
Variable 2D pattern using vertical attractor curve along surface edge, distribution method mean.

3D PANEL TEST PROTOTYPE & TEMPLATE
Cutout template for 3D prototype.
Prototype shows instability of material at the cutouts and is hard to build due to too small tabs and lack of labeling. system.

WEEK 7 READING: DIGITAL FABRICATION
Question 1: What is digital fabrication and how does it change the understanding of two dimensional representation? Digital fabrication falls under Computer Aided Design and manufacturing and describes the process of making using digital data to control fabrication. It breaks down boundaries between architectural design and construction and places architects in a different position. Whilst they need to know about the machines and materials they can be innovative in their designs.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? When folding a two dimensional material it becomes more rigid and structurally supported. Lisa Iwamoto also suggests that additionally it is relatively economical whilst achieving great variation. I can imagine that folding would be quicker than other fabrication methods when prototyping. This makes it easy to prototype small scale models.

EXPLORING 3D PANELLING
Finalised 3D Model of the terrain. Direction of Triangles emphasises the curve of the terain and suggest the forming of two mountain scapes with a river dividing them. The river is shown in 2D panels. The movement of the water is represented by little triangle cutouts emerging from the 2D panels.
