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) Cylinders,cones and tangent surfaces of space curve are the three elementary types of developable surfaces. Cylinders is composed of parallel lines. The unfolding prismatic surface becomes in the limited development of the cylinder surfaces; Cones are consist of profile curves and a vertex point. Those vertices lie at same distance from vertex. When it is smooth, it is divided by some discrete counterparts of pyramids; Tangent surface of space curves are planar curves. It only contains flat points in a discrete polygon with vertices. What is more, any two consecutive vertices decide the edges and any three consecutive vertices define a face plan. In tangent surface, each tangent plan is tangent to the surface along entire ruling and not just in a 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) It is important for us to create developable surfaces for a safe good architectural structure. Developable surfaces contains flat points, lines as well as basic shape and it can not be stretched. For instance, Plasma Studio’s Greenhouse design has developable surfaces, which contains many triangles. The rooftop of the ‘Plasma Studio Greenhouse’ is made of developable surfaces. And the whole geometrical surfaces are not developable.

3D PANEL TEST PROTOTYPE & TEMPLATE There are nine folding pyramids that connected by some small bull nose clips. Apparently, the gaps is not narrow. So with my later final models, I just use glue to fix them. What is more, the dash lines are helpful to recognise the way of folding. Thus I also use this kind of lines to help folding.
Unrolled template
Nine 3D trials
This was the fist trial in class. Unrolled surfaces are in page 47 of survival guide. After I folded them and glued them together, I gradually find an easy way to do my final models.

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 computerized process streamlines production----effectively blending upstream and downstream processes that are typically compartmentalized, often eliminating intermediate steps between design and final production. Like traditional drawing, digital production is a generative medium that comes with its own host of restraints and possibilities. Digital practices have the potential to narrow the gap between representation and building. With the deeper understanding of three dimension, we can get more information of two dimension.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) After folding, materials gain stiffness and rigidity, can span distance, and can often be self-supporting. Folding is theoretical concept, formal tactic, and the most literally material operation. Folding expands the three-dimensional vocabulary of surface by naturally producing deformation and inflection.

EXPLORING 3D PANELLING
Final three dimensional panel Four 3D custom models
This is my 3D image before I removing a half of my 3D patterns. In total, I use four different models to fill my 10 by 10 terrain. By using a curve attractor techniques, the surface of this panel has a different height and becomes un and down.
