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) Developable surfaces S are characterized by the property that they can be mapped isometrically into the plane. Because isometric mapping preserve Gaussian curvature, a developable surface has the same Gaussian curvature as the plane. It has only three basic types of ruled surface under this situation, which are cylinders (a cylinder surface is formed by a family of parallel lines which are called rulings of S), cones (each surface consists of lines which interacts in one point), and tangent surfaces of space curves (a kind of a discrete version of the set of tangents of a space 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) Developable surfaces have great advantage that they can be easily covered with sheet metal, one only needs to roll out the sheet metal bands on a surface. These surfaces carry a family of straight lines—which also simplifies their construction. All of these properties are very attractive for the actual construction, and thus it is used in a number of important architectural projects. In Puppet Theatre, the interior layer is consist of separate plastic panels, which decrease the difficulties of producing panels but did not damage the beauty the building, because they are developable surface.

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) Like traditional drawing, digital production is a generative medium that comes with its own host of restrains and possibilities. It is an architectural and Material Techniques documents architecturally innovative projects realized through digital design and constructive process. Digital fabrication has spurred a design revolution, yield a wealth of architectural invention and innovation.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding turns a flat surface into a three-dimensional one, not only for making form but also for creating structure with geometry. In architecture, folding is theoretical concept, formal tactic, and the most literally material operation. As a material technique, folding is not limited to being a secondary system of articulating the larger building diagram, it expends the three-dimensional vocabulary of surface by naturally producing deformation and inflection.
