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: Tangent surfaces, cones and cylinder. Cylinders are obtained from paralelly extruding a cruve and the paralell lines perpendicular to it (profile curves) along the same direction. Besides, with a presence of a vertex point and a profile cruve, by connecting all lines between them, together them three forms a cone. For tangent surfaces, it is formed by connecting the vertices of a polygon. These lines form a “developable ruled surfaces� called tangent surfaces.
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) Understanding od developable surfaces are critical in the understanding of architectural geometry as these surfaces form a basis of which all complicated built surfaces on Earth can be decomposited into these funamental shapes or easier understanding and better methods of constructing. This can not onky essentially save time and resources, it also provide a bounding guideline for people to invent new architectual shapes and structure. The puppet theatre by Huyghe+LeCorbusier is a good precendent. The roof of the theatre might seem to be a complex geometry, it is actually a developable surface (tangental surface) panelled by trangles of different orientation. This is a good example of showing people how complex geometry can be understood using the funamentals, concept of developable surfaces.

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 the use of computer-aided design technologies to assist with creation, representation, construction, design etc. to achieve the aim of fabricating an object (virtually or physically). It changes the understanding of two dimensional representation as before these technologies appreaed, we are limited to represent one aspect/view of an object per drawings but with computer-aised design technologies nowadays incoperataing 3D features that offer 360 degrees of ways to look at/ deisng an object, It established a connection of our understnading of 2D with 3D.
Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Firstly, paper is a cheap material to be used for reperestation (e.g. model) when compare to more expensive material like metals. Therefore, it provides a economical way to represent a building and accurately deliver information that is needed to be deliver precisely. For example, the building height has to be in scale with the actul construction and paper allows for any scaling unlike some materials are unfoldable or uncuttable. Secondly, any shapes or geometry that a paper can be fold into means there is possible way to build in real life since any shapes that a paper can form is developable. Hence it is valueable to express achitechtral surfaces concept as they are all feaxible to build.

EXPLORING 3D PANELLING
The aim of the final 3D panelling is to provide a surface with a countious pattern. Using Rhino 3D panelling tool (Various) to create a tunel shped patterm, attraction points are set as the outer most points on the vertical line. By selecting these 4 recreated modules and their reflection s to fill in the surface, the mirror pattern is achieved and the modules on the “path” were replaced indiviually to create a “almost flat road” in the middle of the “tunnel”. Bounding boxes of these modules are also intensionally chosen to be smaller than their width so that pattern will be plaid with modules overlapping on the top (the tips extending to limits of other modules).

APPENDIX
Original terriain file was provided and different grids are produceed by using function “ptoffsrtpoints”
Modules are designed for covering the surface. Prisms’ height and width are carefully designed to produce converging pattern to the centre (tunnel)

Final designed was established by redesinging modules serveral times. The 3D panel are customed to represent this particular movie scene in Harry Potter to symbolise “ the only way out is through”.

APPENDIX
Individuals panel is unrolled and added tab to laser print the templates onto the Ivory card for folding.
unrolled panels are removed from the Ivory card ready for folding after printing. Some were damage when removing as FabLab taped the panels firmly onto the ivory card.
Folded modules are taped between glued surfaces to retain structure while drying. Each module is labeled with a unique location coordinate for later combination.
Modules with the same column coordinates are glued to form the entire column. This will later be combined with other neighbouring coloumns.

APPENDIX
Completed comumns are joint by glueing tabs below the surfaces together. The whole model is flipped for easier operations and clips help maining pressure to glued tabs.
Overview of the completed 3D panel model.
Details are doubled checked, including bended corner, seperated layers of card are checked and fixed.
Finally, the whole model is brushed with a soft brush to remove any dust or lumbs of glue.
