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 and tangent surfaces of space curves. These surfaces all have special ruled surfaces in which tangent planes can be created along the entire ruling instead of one single 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 are critical in the understanding of architectural geometry because they allow us to construct physical models of buildings based on models of developable surfaces. Such can be seen in the Cloud Canopy of Melbourne’s Federation Square. The magnificent glass and steel panels of the canopy could easily be constructed with the help of developable surfaces.

PANELLING 2D PATTERN
2d Panelling, Pattern: Triangular
2d Panelling, Pattern: Wave
2d Panelling, Pattern: Custom Pattern I decided on using this pattern because I liked the tesselating geometries.

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 the construction of virtual models in order to represent physical ones. Digital fabrication has replaced traditional mediums of two dimensional representation in order to bridge the gap between representation and building.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding is used in the formal expression of building design because folding converts a flat surface into a three dimensional surface. When folding is introduced to a material, it gives it rigidity and shape. Folds can also be used to develop a wide range of complex geometries. Therefore, these techniques can be applied in real life building design.

EXPLORING 3D PANELLING
Initial 3D model This is the initial 3D model that I decided to go with. I wanted a smooth transition between the 2D and 3D models therefore I went with the curve attractor to offset the grid points before constructing the 3D model.

Final model After producing the 3D model, I removed the low areas of the developed landscape and replaced them with 2D models.

APPENDIX
Mesh surface constructed from NURBS surface.
I chose to use a 42 by 42 grid instead of 10 by 10 because the geometry that I chose occupied a 6 by 6 grid each.
Tools and materials : Adhesives, rulers, cutting tools and clamps, ivory card.
Adhering the unrolled templates to the ivory card.
13
Scoring the fold lines with a scalpel to ensure that folds are accurate.
14
Clamping down the joints while the glue dries.
Issue: Too much tension build-up due to the springy nature of the ivory card. Forcing the panels together caused panels elsewhere to rip apart at their seams.
If I had the chance to remake this model, I would have opted for a lightweight cardstock for the core of the model. 15
Because of the tension in the core, the final model had a massive bow in the middle.
Unrolled templates.

The paper model makes a good lampshade.
