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) Three basic types of developable surfaces are: 1, Cylinders that contain a family of parallel lines and right angles. The curve on the top can be divided into small straight segments. 2, Cones that consist of 2 families of circles, one is parallel to the base and the other is parallel to the top plane that is a slope. 3, Tangent surfaces of space curves that one ruling (a curve) has the same tangent plane. They are specially ruled because their tangent surfaces for rulings are always tangent for one same ruling instead of only at a point.
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) Developable surfaces can be easily covered with sheet metal and can be more easily built in construction therefore very useful in architectural design.

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

VARIABLE 3D PATTERN
This is one of the patterns I tried that geometries are distributed is in squareshaped circles.

This is a lanscape i tested along the process. Pyramids and box-shaped geometries blend in with each other.
This landscape has a circle of pointy pyramids that contrasts significantly in the entire landscape.

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 new technologies using computers relating virtual models and physical models together, as a medium between design representation and actual making. It is easier for viewers to visualise when presented in 3D modelling with digital fabrication, replacing 2D presentations.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding is widely used because it translates between two-dimensional and three-dimensional objects, on one hand turning two-dimensional surfaces into three-dimensional ones on the other creating planar surfaces that are easier to build for three-dimensional objects. Another reason is that folding enables natural production of deformation and inflection that explore more about the surfaces.

EXPLORING 3D PANELLING
This screenshot is taken after the attractor point was decided to be around the higher part of the terrain.
This screenshot shows attractor point is around the highest point of the terrain.
I also tried to select multiple points, change the position of the point but chose a point outside and around the higher part of the terrain.

APPENDIX 1, digital making process
This is the slide-shaped curvy terrain I was assigned to. At first I wanted to create a contrast of height in the landscape. As I was trying along, the idea occurred to me that I can make circle, semi-circle or quarter-circle shaped landscape, also showing contrast in height. So I selected similar objects (with different heights of bounding box, an angle slightly twisted or different mode of offset points of the terrain ) multiple times to create a landscape that is of some consistency but also variations. I used pyramidshaped objects, 2 in 1 grid, and twisted or not twisted boxes (truncated square), so they show different shadows. Also I tried out using different modes of offset points and bounding boxes of different heights for the same or similar object, then panelling them according to the heights to adjust the height contrast in the landscape. I chose the most aesthetically pleasing one to make my physical model that is 10 quarter-circles with all slightly different geometries, showing the slide-shape of the terrain. A screenshot showing testing different geometries.

This is one of the five A1 templates i had for my final model.
12
I unrolled geometries in the centre 50 grids, arranged them in illustrator and got them printed out. Having tested different ways of joining them together before unrolling them, I decided to unroll them individually, grid by grid or object by object, so they do not stretch too much and easier to glue.
2, Physical model making
After making the model for first 50 grids, I was running out of time so I got the rest laser cut.
Later on the resistance force they have was too great, it was too difficult to glue so I started stapling them together.
These are a few of pen knife cut objects in the centre of the final model.
