Week Three

Reading: Kolerevic B. 2003. Architecture in the Digital Age

Kolerevic described three fundamental type of fabrication techniques in the reading. Outline the three techniques and discuss the potential of Computer Numeric Controlled fabrication with parametric modelling. (150 words max)

According to Kolerevic, three fundamental fabrication techniques are subtractive, additive and formative fabrication. The subtractive fabrication is the technique of taking materials out off the object to create a model while the additive technique is the form of layered manufacturing. The formative fabrication is the flexible type of fabrication where the object is created by shaping into desirable product. In formative fabrication, different materials can be shaped into single product which allows for financial and design flexibility. As the design processes become complex, a specific type of fabrication is needed to produce series of variable geometries. Therefore, Computer Numeric Controlled fabrication is essential in producing such variations with limited quatity of materials and low cost.

Week Three

Surface Creation

Firstly, box is created in grasshopper and lines are deconstructed to create surface edges. The points are also constructed on the box edges to create surface points. Then variable surfaces are produced by baking the surface lines tested above. Among several surface iterations, two surfaces are chosen to create 2d and 3d panel .

Week Four Panels & Waffle

Simple square opening was created for 2d brep design and panelled to produce 2d panel. In terms of 3d panel, curve attractor is used to guide the 3d panel attraction. Small and sharp edged mountain shaped panels are layered to create above 3d panel surface. The permeability of 3d panels also differs based on different angles.

4

The waffle structure of the model serves as both base and interior structure for the 3d and 2d panels. It also portrays the thereshold between 2d and 3d panel surfaces. The patterns of 2d and 3d panels are reflected inside the waffle structure.

Firstly, 3d and 2d panels are converted to mesh surfaces and unrolled. The tabs are then put at the edges and these were set as cut line in laser cut file. Moreover, the fold lines are set as the etch lines in laser template. The limitations that I faced during putting the laser template are some surfaces had to be exploded and joined again since make2d command makes some of the lines disappear.

Week Five

The cube is created in grasshopper to set as a boundary for the model. Unique model is then constructed and panelled with point attracts to create intersections between the geometries. The overlapped geometries are then subtracted from the cube by the use of booleandifference command. The intersections were then left with openings and small fragmented spaces.

Week Five

Isometric

The model explores the idea of light and terrain. The different sized openings of the model give different sense of spaces.

Large openings of the model suggests both light filled interior and positive spaces. Whereas, small fragmented spaces created when the geometries only slightly touch the object is interpreted as the negative and enclosed spaces. Furthermore, the rough steps at the base of the model not only shows the rough nature of the terrain but also guides the circulation throughout the space.

While creating iterations for task 1, I tried to choose a surface that would not have intersections and developable surfaces. The curve attraction in the shape of sharp mountain edges is then set to create the panel surface. This is also refllected in the individual 3d panels. The folding lines of the 2d panel represent the path of openings which allows light to pass through and create patterns inside the waffle.

Task 02 Matrix Whiile iterating for task 2, I chose distorted cube to create iirregular intersecting geometries. The geometries are then panelled to different sizes to portray the different open spaces. The booleaned geometry is then cut where there are more intersections to show the entrance and circulation path.
