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)

Kolerevic described two-dimensional fabrication, subtractive fabrication and additive fabrication. Computer Numeric Controlled fabrication is also called two-dimensional fabrication, it includes laser cutting, plasma-arc cutting and water-jets cutting. Parametric modelling uses the computer to design objects. Parametric models use solid and surface modelling design tools to manipulate and play with system attributes. Parametric modelling allows designers and architects to define entire classes of shapes and create variations easily. For example, with parametric modelling, designers only need to alter one parameter and the other parameters will be adjusted automatically for them. Therefore, cnc fabrication should work effectively with parametric modelling.

Week Three

Surface Creation

When generating these iterations, i just tried out different options using the number sliders. I changed the directions of the four edges of one surface and then changed the positions of the points to create lines.

Week Four Panels & Waffle

I used a combination of 2d panel and 3d panel.

Since the two surfaces i used were quite flat, the waffle structure is not very dramatic.

After unrolled the surfaces of the panels and the fins of the waffle, i used Make 2d to make them curve. Then, i copied these curves into

Week Five

I used different methods to generate these boolean iterations, point attraction, curve attraction, random attraction and weight attraction. Also, i tried different geometry options in Weaver Bird rather than just trying spheres.

Week Five

Isometric

I chose the final solid boolean based on the time it takes and its relation to ‘Radix’. My model has only a few part of the cube left, which means its very porous and permeable. The middle hollow part of my model looks like a series of domes and they form a space together. The solid parts are like a threshold as a whole. Public and private spaces can be distinguished.

Week Six Task 01

Task 01 Matrix I chose to go for the safer option because if the surfaces are too curved, there will be some problems processing it in Grasshopper. I chose to use three different objects for the variation of the 3d panel and for the 2d panel, I just go for the basic one with perforations.

Week Six Task 02

Task 02 Matrix I chose to use point attraction to find the distribution of spheres and reverse attractor was used to form the intersecting geometry (group of spheres). When boolean difference the cube with the geometry, I chose to keep the part that most of the cube was cut because it allows the creation of more interesting spaces.
