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)
Cones, Cylinders and tagent surfaces of space curves are three elementary types of developable surfaces. They commonly share the property that can be mapped isometrically onto a plane and for each ruling having a plane tagent to the surface along the entire ruling. For example, cones have a profile curve and a vertex point connected by lines lining with constant distance. Cylinders are formed by series of lines parallel to a profile curve. A space curve is the curve may pass through any region of 3D space involving a three dimensional curve and surface based on the tagent of the curve.
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) Because these simple shapes are easily mapped into any plane in 2D without stretching or tearing which contrustruction will be able to manage the manipulation and configuration of 2D materials. In addition, it allows architects to creat simple yet unique architectural structure design for buildings based on different criteria. Califonia stage as one of the example, designed by John Jasperse, is made up of individual segments which piece together. It can be assembled within hours meanwhile achieving a transformable and spatially changing effect.

ANALYSING THE TERRAIN & TESTING OUT OFFSET POINT
BENDING UPWARDS BENDING UPWARDS BENDING UPWARDS
BENDING DOWNWARDS BENDING DOWNWARDS
BENDING DOWNWARDS
BENDING DOWNWARDS
Base on the geometry of the terrain, area that bending upwards should have heavier geometry whereas the part bending downwards should have lighter objects on it, due to the effectof gravity.
Offset points were therefore set by using curve attractor, having the “appeal” model on. The lines drawing on the surface show the basic flow of where should be dragged down. This instructed the offside point to create height. Short length to avoid ovedone heaveniess.
The heaviness could be generated firstly by adjusting the height of offsetpoint for each geometry. Those higher geometries will have larger surface area which need more paper for the actual model, which add on weight to that area and help drag the surface downwards.

3D PANEL DESIGN circle pyramid
rectangle pyramid
triangle pyramid
Rright view of final design for geometry: Height of geometries are designed to be ncreased gradually to present transmation. Variation is shown through different direction of “openness�
Comparison through three different shapes: (Reason that chosen the triangle pyramid as prototype for the model) 1. The circle pyramid has undevelopable surface as the unroll overlapped. 2. The rectangle pyramid has developable surface, but less stability. 3. Not only is the triangle pyramid developable, it is also a stable shape. Enabling to create complex effect for the model yet with simple structure.
Perspective view of final geometry: Pyramids have a good showing of pure light interaction

VARIABLE 3D PATTERN
Four straight lines as curve attractor was used to create further variation which match the characteristic of landscape surface
Two straight line sas curve attractor was used to create simple parallel transition
For the first two 3D pattern experienment, this special shape was added for experienment as well which has great effect on presenting height. However it doesnt give a smooth transition between each geometry, the overall effect seems isolated.
Further curve attractor experienment are carried out for more complex variation on the landscape. the special pattern were replaced. Using three curves to create variation on the landscape

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 computer based design process using three-dimensional modelling software such as CADS to control a facrication process. It changes our understanding of two-dimensional representation by shortening significant amount of time for architects from designing and making final products while keeping the good quality through different use of techniques such as sectioning, tesellating, folding, contouring and forming.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding is extensively used mainly beacuse of its effectiveness in create forms and affordabled cost. Folds introduced into two-dimentional materials gain sitffness and rigidity,it can turn a flat surface into a 3D structure without losing the nature of material. Besides, it is maeterially economical and visually appealling, folding expands the three-dimentional vocabulary of surface by naturally producing deformation.

EXPLORING 3D PANELLING
First Test
Second Test
Two test for the landscape character was carried out at the same time. One focus on the curve, spiral and floating effect whereas the other one emphasis the relationship among mountain, hill and the plain. Comparing the two, the second one is more ideally chosen for this module. Not only because it stands out with its great showing of height, it is also more developable for actual model as it has clearer vartiation between areas.

UNROLL TEMPLATE OF FINAL MODEL
For this module, the key idea is to use simple shapes creating complex effect and showing variation on landscape. Many of the geometries are able to unroll in groups. Folds are sorted in column are noted in different colour foe better recognition.

--rule for straighten the line --knife used to cut out the outline and score on fold lines --all adheresive glue was effectively used for this modle. --different types of clips were used to hold the glued tabs. 50% of folds were cut on ivory card
extrme small size brush was handy to be used for fixing gaps and holes on model
