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) The three basic types are cylinders, cones, and tangent surfaces of space curves. The cylinder surface is formed by a family of parallel lines, which made up with a profile curve p and extrude iy in some direction r by a parallel extrusion. Cone is defined as combination of a profile curve p and a vertex point v, as all lines are connecting the v and p. And cone surface is a central extrusion. In tangent developable surface, and two consecutive vertices determine the edges, and any three vertices determine a 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) Take the Huyghe & Le Corbusier Puppet Theater for example, the theater is built with 500 unique white polycarbonate panels. As they are simply bolted together, they are easily assembled and disassembled. Both interior and exterior are with high aethetic value, and constructivey effective.

WEEK 7 READING: DIGITAL FABRICATION Complete your reading before attempting these questions:
Question 1: What is digital fabrication and how does it change the understanding of two dimensional representation? (Maximum 100 words) Digital Fabrication is defined as architectural and material techiques, illustrates the innovative projects realized through digital and constructive process architecturally. Like traditional drawing methods, it is a generative medium with its own restrains and possibilties. Moreover, it is able to narrow the gap between representation and building, affording a hypotheically seamless connetion between design and construction.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding, as one type of digital fabrication techiques, is materially economical, visually appealing and effective at multiple scales. In economic aspect, folded construction as a simpler geometric model, has the potentiall of casting concrete into form. As for effective at multiple scales, it offers the greatest potential for variety, as it is inherently capable of manifesting a wide of forms.

EXPLORING 3D PANELLING
Use two types of 3D pattern to build a “face”. The left part pattern is the combination of cube and rectangular pyramid, right one is the quadrangulars with different height and angle of top surface. Two parts with various patterns also tell the differnences between linework and plane. As for 2D pattern, I don’t want it be to complex, I choose the simple box pattern as a background of the face at the linework part.

02. Use Rhino to build my own model
1ST TRY difficult to join every 3D patten together at bottom
2ND TRY use “loft� to lof a point in the middle of the square to build the model But it is not able to add the tab on the unrolled surface Gap between each surface
1ST UNROLL SURFACE test the unroll surface using my first pattern
2ND TRY Try to mesh it and unroll the nurb Still not woriking Unrolled surface is overlapping after explode and join again

03. Use Rhino to unroll the pattern into developable surfaces
Because the patterns I used contain squares, I can’t join the 2D and 3D patterns together then I unrolled them separately
