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) Insert your answer here....

There are three elementary types of developable surfaces; cylinders, cones and tangent surfaces of space curves. These three elements share similar properties which allow these particular types of surfaces to be developable. This is that a tangent exists along an entire ruling on their surface and not just a single point and they share vanishing Guassion curvature because their Gaussian spherical image is a 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) Insert your answer here....

Understanding developable surfaced allows the formation of architectural geometry to be utilised and knowing what can be physically constructed with paneling. ‘The Greenhouse’ developed by Plasma Studio, is an example of the utilization of triangular panels of various sizes to develop a panel that can form a flat surface for construction. Together small triangular panels formed to create larger triangular sections to which formed the overall construct of the overall Greenhouse.

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) I Digital fabrication is the use of computer aided drawings and design to digitally develop and construct physical products, such as models or elements for construction. Digital fabrication can quickly and accurately represent concepts that stem from two dimensional drawings in both electronic and physical environment. This is useful as models can be developed quickly and idea refined before the digital information of the design is used to develop physical components for final construction. Therefore, it allows the collaboration between the digital model and physical artefact which enables architects to explore concepts prior to development and enhances the process from design to construction.

Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Folding allows flat surfaces to be transformed into three-dimensional which useful in building construction and building aesthetics. Introducing folds into otherwise planar material allows stiffness and rigidity to form which enables a surface to span distance and often support itself. Folding expands the three-dimensional terminology of surface by naturally producing distortion and variation. Therefore, folding is a vital and useful technique for forming building design for construction as structure and form can be created with geometry, allowing a two-dimensional surface to be modulated into three-dimensional spatial construction. Furthermore, folds are aesthetically pleasing and draw on historical craft design creating a sense of uniform across surfaces that are traditionally unconnected.

UNROLL TEMPLATE OF YOUR FINAL MODEL

Selection of Panels unfolded with tabs using Rhino, ready for print and construction Example 17 is variants 1,3 & 4 joined together and unrolled. Example Q is the 2D pattern unrolled. It was important in the design process of the 2D pattern to have a concept that would ehance and strengthen my final polysurface. As seen in M, the 2D unrolled surfaces are joined easily.
