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 elementary types of developable surfaces are cylinders, cones, tangent surfaces of space curves. A tangent plane is ultimately tangent to the surface along an entire ruling, instead of in a single point. A developable cylinder surface is formed by a family of parallel rulings. Whilst, cone surface consists profile curve, vertex point and a series of lines connecting profile curve and vertex. A tangent surface of space curves incorporate polygon and vertices and it is more complicated than other two elementary types of developable surfaces.
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) The understanding of developable surface is critical to the understanding of architectural geometry. Huyghe+Le Corbusier Puppet Theatre is an example of utilising simple geometric shape to create a rigid structure. Due to these polycarbonate panels are simply interlocked together, they can be easily constructed or deconstructed. Which indicates the importance of the use of developable surfaces in the architectural geometry.

PANELLING PATTERN
2d Panelling, Pattern: Triangular
3D Panelling: Pyramid 1
3D Panelling: Pyramid 2

VARIABLE 3D PATTERN
3D PANEL TEST PROTOTYPE & TEMPLATE
This iteration is formed by diamond panel surface shape, with the command of Ptpanel3DCustom. The variation of height is determiend by the offset points along the polylines.
This iteration is formed by the alteration of pyramidal pattern, using the command Ptpanel3DCustom. The variation of height is determiend by the offset points along the polylines.
This iteration is formed by three types of paneling objects: Alteration of pyramidal pattern, diamond panel surface and pyramid. Rhino command Ptpanel3Dcustomvariable is used. The variation of height is determiend by the offset points along the polylines.

Some panelling objects were separated from the prototype terrain, using the commands such as meshtoNURB and unrollsurf and unrolled into single strips. Tabs were added to help glued the strips together. The dash lines on the strips represent the areas need to be folded.
The prototype is made to testify the feasibility of the final model, and investigate the optimum solution to connect each panelling

WEEK 7 READING: DIGITAL FABRICATION
EXPLORING 3D PANELLING
Question 1: What is digital fabrication and how does it change the understanding of two dimensional representation? (Maximum 100 words) Digital fabrication is a manufacturing process using an architectural and material technique such as 3D modelling software. It spurred a design revolution and generating a wealth of architectural invention and innovation. This process has changed the understanding of two dimensional by providing a more accurate structure and details. It makes designer operate digital drawing easier and more precise. Thus, designers can create a more complicated geometrical structure with less difficulty.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding is used extensively in the formal expression of building design. Because it is a powerful technique for making form and creating the structure with geometry by transforming two dimensional into three. It produces deformation and inflection while expanding the three-dimensional vocabulary of surface.
