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 that Kolerevic described in the reading are two-dimensional fabrication, subtractive fabrication and formative favrication. Two-dimensional fabrication is the most commonly used fabrication technique. The additive fabrication is the removal of a specified volume of material from solids using electra-, chemically- or mechanically- reductive processes. Moreover, in formative fabrication, mecahnical forces, restricting forms, heat or steam are applied to a material so as to form it into the desired shape through reshaping or deformation, which can axially or surface constrained. The potential of computer controlled fabrication with parametric modelling is that computer numerical contorl machinery with parametric modelling allows the fabrication of complex designs directly from the computer software. It is a good way for architect to draw and build more accuratly, meanwhile, the way to create information that can be easily translated by fabrication so they could control data and see the outcome.
The Grasshopper Surface Script
The left image shows the route that how i create the surface in Rhino, the bounding box is created first and then deconstrcted to create for curves. By listing points and dividing curves to produce two surfaces within the bounding box, the four different types of surface iterations are created.
Week Four Panels & Waffle
The waffle is used for supporting two surfaces, this angle of view is easily to see how the structure looks and the shape of the surfaces. A hollow waffle structure allows for the creation of an interior volume.
The panelled surface are generated from two different types of panels, 2D and 3D panels. Solid panels create a definitive boundary between exterior and interior. Hollow panels create an interesting shadow when the is crossing through.
During the process of creating the laser cutting of the panels. I first unrolled the every single panels in Rhino, and added tabs to them, then placed into laser cutting format, the one of the important things is seperate the cut lines and etch lines into different layers. I was make confused in my first attempt printing, so because of this reason, i became more careful on the following printings. Moreover,all the objects should be labled with location numbers beside, it is helpful for building model.
Grasshopper Script Shape Transformation The process of beginning was create a bounding box and generated the grid. The grids is used for manipulating the point attractor and it effects the transformation of the shape. Different types of effects such as random attractor have been tried for shape transformation to produce various size of geometric.
The model is created by the shape of platonic octahedron within the bounding box. The porousity and permeability of the model is created by the intersecting shapes that are substracted from the bounding box. Observing from the section cut of the model, the shape that is subtracted created square openings of different sizes to allow light to penetrate into the structure, illuminating the inside space. Moreover, the form of the model concaves at the parts which are subtracted out by the shapes and terminatesat the openings. The voids created have an interesting geometrical shape and sharp edges, resulting in different intensity of lighton each interior face.

Week Six Task 01
Attractor / Control Points (X,Y,Z) Attractor / Control Curves Grid Points
Paneling with Sunshine
Task 01 Matrix After making iterations of four different surfaces, the right one is my final chosen. Due to my module1 study-Libeskind pavilion, iâ€™m exploring to find relationship between the waffle structure, shadow and movement. This two surfaces allows more space in interior. Then, the solid paneling grids is chosen so that could be allow more movement for people. Lastly, the 2D panels and 3D Panels are mixed togther to create interesting variation interms of light entering the structure.
Week Six Task 02
Attractor / Control Points (X,Y,Z) Attractor / Control Curves
Task 02 Matrix The grid that is manipulated using 3 attractor points is used as it creates a octahedron inside the grid, the regular distribution of the shapes is chosen to maintain the simplicity. Lastly, the shape transformation using the random point so that the size of the shapes vary from small to large throughout the grids.
Final Isometric Views
Using grasshopper to create two surfaces
Baked two surfaces from the bounding box
Creating the domain surface number on each two surfaces.
By using panel custom 3D, align the own design object to the surfces, then baked the surfaces from Grasshopper to Rhino.
Based on the two baked surfaces, using the grasshopper to create the waffle structure in between.
Print out the laser cut format and make the physical model
Using the Grasshopper to label on the laser cut format.
The waffle structure
The waffle structure
Create the bounding box with grids, using the attractor point change the grids.
The solid shapes are subtracted from the box using the Boolean difference command.
Platonic Octahedron is used to creat the solids in each grid. Different variatons are made using variaous attractors.
The solid is then cut using boolean difference function to create the final product.
