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 are subtractive, additive and formative. Subtractive fabrication technique includes laser cutting and CNC miling. To control the position of a cutting tool to carves away the specific area of the material, its normalyy using 3 to 5 axes. Additive technique involves incremental forming by adding up materials layer by layer. In formative fabrication, heat and steam are applied to a material to reshape or deform it into the shape that we want. Computer Numeric Controlled fabrication allows the higher potential in the parametric modelling, since the data transfer directly from computer into machine to generate the final model. It could provide a chance for faster and more flexible production process for the design work with CNC and can be manipulated easily by editting the script to gain a variety of prototype model.


Week Three

Surface Creation

These are my selections of two surfaces and the script to produce them. I change the shape of a surface by simply changed the number of slice bar in grasshopper on the left to gain the effect picture on the right. I kept one surface not changing and tried to find out the shape of the other surface. From my experiments, I thought the twisted may be looks better with a flat surface because it can emphasis on the form of it comparing with the flat surface.


Week Four Panels & Waffle

This is my paneling, the front one is 3D panel and the one in the back is 2D. I designed the 3D panel to be

This is the waffle structure of my designed model. The structure is inclined, and the structure is large on the

closed structure and the 2D panel to be open, so that people could have different experience when they

top while small in the bottom. Its quite differnt to look when its sticking together with the panels because i

see the front and back of the structure.

designed the form of the 3D panel to be larger in the bottom, which is opposite to the waffle structure.


Week Four

Laser Cutting

This is the file that I send to lasercut. You can see the line weight are heaveier with the cutting lines and the thiner lines are for etching.

The 2D panel of my model is completely flat so that it saved some time and money for me to send to laser cut.

I placed the objects contineously and in order, and it helps me to check the progress when I was doing physical model.


Week Five

These are the 4 different shapes that I have tried embedded into the script, I show the negative space because it’s clearer to see in this way. I tried the basic shapes in grasshopper which looks quite regular, then I designed my own shape in rhino which is the last image the large corn trimed out a small corn in the center. The script in the left shows the process of how I did it.t


Week Five


Insert a brief description of your isometric here. Comment on the process of choosing which iteration to develop and 3D Print.

What are some of the spacial qualities of your model? How does it address porosity and permeability? The structure of each grid is a smalle corn inside the large corne. I consider it as a small area inside of a large area therefore it may maintain different extent of privacy and can be multifunctional in each area. Idea comming from previous pavilion (Zumthor pavilion). The pitching shape pointing towards the curve area, graphically seems to be in contrast , the two area nearby may be in compltely different function. If we invert the psitive and negative space, this could be a contineous curvy path. People may be walking slower at the long path and the turning points can set some attracting spot to catch their eyes. The space here connecting to the inner area, in the same time it can be view from the outside of the structure. However the corn shape inside would block the view to see even inside.

Week Six Task 01






150,0,150 (0,0,150)






(150,150,60) (150,0,45)







(150,0,0) (25,150,0)



Task 01 Matrix These are the matrix for task 1, I showed how I decided the choose of my two surfaces.Then I have the prototype of models changing in scale by using side bar in the script. Finally I have the different combinations of panels.I didn’t choose the ones other than my final design is because they are either really simple and lose of flexibility, or they may be too complicated that have too much problems need to be fixed in a short period of time.-

Week Six Task 02

(150,63,148) (65,-14,8)


(150,-19,148) (150,63,148)


Task 02 Matrix These are the matrix that I did before reaching the final model that I made. I firstly tried to fill different shape in grasshopper into the the cube, which doesn’t look too good, then I decided to design the shape by myself. I also tried different number of grids in the cube and I tried different attraction point and attraction curve, I chose the one that not looking to complecated because I want to keep the model simplw.Then I tried to scale the model by changing the number of slice bar in grasshopper, I changed the slice bar until it can mostly present my model in twisted order.


Week Six

Final Isometric Views

These are the isometric view of my final model for task 1 and task 2, both of them compound integrate of openess and closeness.




These are my model of task one before sticking together, they looks clean and eadges are clear to see. The model take advantages of the laser cutting and uhu adhesive.


Appendix Process

This is the grasshopper file for task 2, in order to add my own shape into the grid, I ebedded the morph 3d command for each level of grid. That is consider one level of grid as a 3d panel. I used the same brep for each level to reduce some complexity. but it is possible to set multiple types of brep into the model.

This is the script to make the hexigon panel. it could be 2D or 3D, I decided to use 2D because in my case the pavilion is inclining in one direction and it doesn’t look so good if the both surface contains 3D panel.
