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)

The three fundamental type of fabrication techniques discuessed by Kolerevic is subtractive, additive and formative.

Subtractive fabrication is cuting a volume by removing material. There are machines with different number of axis, which allows complex job and creates more flexibility for production.

On the contrary of subtractive fabrication, additive fabrication involves adding small amounts of material and gradually form the object. This fabrication method as known as layered manufacturing, for the process is completed layer by layer.

Formative fabrication is using the force, heat or restricting form created by machine to reshaping or deformation the material, such as steam bending timber. That helps to large scale CNC (Computer Numeric Controlled) favrication has the potential to provide parametric modeling in a more accurate and effective level. It also make the modeling of shapes with complex calculation to be possible, which can save money, labour and time.

Week Three

Surface Creation

The script starts with building a cube, which is 150 x 150 x 150.

Then use the side as parameter.

It is important to group the commads so that you can get a easy read script when you get back to change or fix up things.

By changing the parameter on cube edge, the different loft surfce is created.

Week Four Panels & Waffle

Two 3D panels with triangular openings create a uncleaer boundary between exterior and interior, which light can go through.

The protruding forms helps to create interest through light and shadow.

The space between panels are smaller at the top and back and increase in size towards the bottom and front of the volume.

4

A hollow waffle structure allows for the creation of an interior volume.

The space between panels are smaller at the top and back and increase in size towards the bottom and front of the volume.

Week Four

Laser Cutting

For the 3D Panel: “mirrior� - decides on which side the line will be.

Etch on ivory card may cause the layer separate while folding. Dash line may be better.

For waffle Structure: Make 2D to avoid repeating cut.

Explode the text also helps to save time and money.

Week Five

The boolean script starts with building a cube, which is evenly divided into 9 parts later. Then use attractors to manipulate the internal structure of the cube. Next find the centriod, which is the centre of the boolean geometry inside the primary cube.

As for the 4 different boolean iterations, I tried to experiencing the different: attactor (left 2 is curve, right 2 is point); geometry (sphere, icosahedron, dipyramid); cut way (triangular prism, cube).

Week Five

Isometric

With the booleaned geometry contained mostly within the original shape the cube is still highly visible as a form.

The Geometry is increasing in size from bottom to top, which means the opening space is increasing The solids left in the middle works as main structure of the boolean, and also makes the behind part of each perspective hidden from audience, which creates a sense of private.

On the right-hand side, where the intersecting geometry interacts with the surface and been cut through creates cantiliver with more open space.

In terms of porosity and permeability, this structure is quite linear.

People can get throuth the struture from bottom to top or around the primary structure in the middle.

Task 01 Matrix For the panel, I chose 1.4 because it creates contrust in both horizontal and vertical.

For the brep to panel, I chose 3.4 and with triangular openings on it, which creates an interest of lignt and shadow.

Task 02 Matrix As the task 1 is relatively irragular in primary structure, I chose a more basic primary structure for task 2 (1.1). With the attractor point on the extended line of diagnal line, the geometry inside the cube becomes bigger from bottom to top, and back to front.
