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, tangent surfaces of space curves. These developable surfaces can be mapped isometrically onto a plane. They are considered special ruled surfaces as a tangent plane is always tangent to the surface along an entire ruling and not just in a single point. Furthermore, they have the same Gaussian curvature as the plane because isometric mappings maintain Gaussian curvature.

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 aids one in physically construct the surfaces in three-dimension. Referring to the stage set for John Jasperse, California, it was designed as a morphing structure that allowed the dancers to engage directly with the architectural piece. By making use of simple geometric patterns, such as a triangle, allowed it to join to form the transformable model.

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 a way of making that uses digital data to control a fabrication process. It has created a potential for architecture to move more fluidly between design and construction. It also increases drawing efficiency, ease of editing and its simplicity in making two dimensional drawings. It has also helped to energize design thinking and expand the boundaries of architectural form and construction.

Its ability to generate construction information directly from design information, and not the complex curving forms, is what defines the most profound aspect of much of the contemporary architecture.

Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words) Firstly, folding offers perhaps the greatest potential for variety because it is inherently capable of manifesting a wide range of forms. Creased surfaces, folded plates, and wrapped volumes all fall within the purview of folding. These building methods share a share fabrication process to make two-dimensional templates for cutting.

Secondly, folding provided structural stiffness. Engineer-architects, in the past, strove for structural elegance and material lightness in the shaping of thin-shell concrete buildings. These projects were frequently designed around creased forms and hyperbolic curvature to create roof structures. The relative ease of making such formwork, along with the structural potential of casting concrete into a folded form, made an efficient and popular combination.

Simple 3D panel using triangle shape

First problem encountered when creating 3D grid. Should not have done it on the panelised 2D grid.

Tried to visualise how a 50% 2D and 50% 3D would be like

Plan Views of Wave 2D grid

This is a comparison between using flatfaces and faces when creating 2D panel.

As seen from plan view, there are no noticeable differences.

Perspective Views of Wave 2D grid

From the image above, it can be seen that there are gaps when flatfaces is used in the wave 2D panel.

However, from the image below, it can be see that there are no gaps in both grids.

Major Issue Faced: Unrolling

First neatly laid out unroll document

Final neatly laid out unroll document

Firstly, I wasted a lot of time and money in trying to reprint these correctly. Secondly, the root cause of my unrolling problems was due to the fact that my 3D surfaces had a mix of frontfaces and backfaces. This was due to the similair colour schme that I had set in the beginning. I learnt that something so small can really destroy all the work one put in, therefore it is always important to be more catious and detailed from the beginning as it cam minimise mistakes.

The result of my unrolled surface (with explode on) lead to a painful series of cutting and gluing small tabs.

TrigulateMesh was the reason to why my surface could not be unrolled neatly like others, it created many unnecessary lines which resulted in the creation of many small triangle, therefore increasing my work load.
