Critical Reading: Kolerevic B. 2003. Architecture in the Digital Age
Kolerevic described three fundamental types 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 types of fabrication techniques discussed by Kolerevic are Subtractive fabrication, Addictive fabrication and Formative fabrication. Subtractive fabrication is removal of a specified volume of material from solids by milling. The milling can be axially, surface or volume constrained. The number of axis of the CNC milling machine determined the complexity and limitation of the form it able to create. Addictive fabrication on the other hand, involves incremental forming by adding material in a layer by layer process. All digital model is sliced into two-dimensional layers. For example, the 3D printing, layers of ceramic powder are glued to form objects. Formative fabrication uses external forces such as mechanical forces, restricting forms, heat or steam to material to form shapes through reshaping or deformation. Computer Numeric Controlled fabrication not only increase the accuracy of the design but also gives the opportunity to create more complex surfaces and structure in an efficient and economical way. The digital design data can be directly transfer into physical model through techniques mentioned above which save time and money.

SURFACE AND WAFFLE STRUCTURE Surface Creation
During the process of creating scripts, I find out that Grasshopper is more accurate in creating and adjusting models than in Rhino, because it has number bars and list item to control during the process. During creating the surface, I tried different orientations of the surfaces and bake them to compare with other options. These three results are the basic composition of the final model and the main process of each workshop. It clearly showed the transition of a simple surface to complex structure and panel skin.

Isometric View
After doing the studied of circulation of the Edinburg pavilion in Module one, using the same approach, the waffle structure is constructed following the enclosed form with one entrance.the entrance is triangulated and the under 5 panels removed to form a high entrance and form a pointed triangle shape. It has small entrance and wide interior space which is similar to the Edinburg pavilion. It also has the wall that lean towards the inside which form a relatively enclosed space. The grey area are interior space and the entrance.
The panel was made by Pyramid shape with gradually varied triangle openings on the surface. Light form the openings form thresholds to divide different function areas, which are The public area and private area. The grey areas are openings.

Like what I learned from last year, I was using unroll commend in rhino, but on workshop I learned how to unroll structure in Grasshopper. It is much more efficient and organized. I put panels close in order to save time while laser cutting.

SURFACE AND WAFFLE STRUCTURE Matrix and Possibilities
Using the studied of circulation of the Edinburg pavilion in Module one, using the same design approach, I gradually changed the opening space in these five surfaces and find the best option to form an enclosed space.

SURFACE AND WAFFLE STRUCTURE Photography of Model
The panel was made by Pyramid shape with gradually varied triangle openings on the surface. Light form the openings form thresholds to divide different function areas, which are The public area and private area. The public side is the right side which gets interaction with outside views and activities and people. The private side is the left side which is a sitting area and exhibition area which can get light from the other side buy without interruption and noise.

SOLID AND VOID Surface Creation
I use two line of grid instead of three because three grids is too much geometry and complexation to create a inner space for my design. I chose the pyramid shape to create space with leaning walls and triangle openings. The Image 1 is the triangle geometry I used to form the interior space. Image 2 shows the geometry intersecting with bounding box to create openings and entrances.

SOLID AND VOID Isometric view
In module 1 pavilion it has openings for interaction and air circulation. I chose the pyramid shape to create space with leaning walls and triangle openings. The section under shows the interior space. The dark gray area are the openings which form entrance and opening windows for view capture. The light grey area is the panel for exhibition and to lean on and have social conversations.

Task B Matrix Through the processes I create different panels to form a low entrance and wide inner space with intersecting the bounding box to make entrance. I chose the last one to further developed because it is relatively easy to control and create the space I want. It also Booleans out the triangulate interior space.

Photography of Model
This is a small pavilion that attract passenger to get in and see what is in the other side. It creates the sense of protection and safety because it is semi-enclosed. It also has the sense of mystery. The shadow it creates for the other side divided the two space into different functional areas. The side with enough light is public area and the side with shadow is the private area.
