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 techniques are subtractive, additive and formative fabrication. Subtractive fabrication is done by removing volumes from a solid to give the required structure using various milling methods. As a contrast to this, additive fabrication adds material layer by layer. The 3D structure made through this method would be calculated into numerous thin layers for fabrication. Last but not least, formative fabrication is without adding or removing materials, but simply shape the material via heat or steam, pressure, etc. The above three methods are done through Computer Numeric Controlled process, where the product is analysed into data, such as layers in a plan and axial values. Processed as messive data, dots are lined to curves and curves are laid to a layer, and the layer is integrated into the final 3D model. Theoretically, this method is universally applicable, though financial and time cost do need to be considered.


Week Three

Surface Creation





Creating from the first attempt, where 2 surfaces cross intersect with each other. They are not that curvy so the second one I tried with another intersection where one become more curvy and one remain flat. In the 3rd one, 2 surfaces are not intersecting while they look like intersecting. The 4th one is about 2 parallel surfaces, which informs my final design of the surfaces. In the final one, 2 surfaces are parallel at the bottom. As it goes up, one side remains the parallelity while at the other side, one of the surfaces curved away. In this way, I want to create a sense of unity, as well as contrast.


Week Four Panels & Waffle

The 2 sides are made with contrast. On the straight surface, bulky solids combining with hollow panels enhances the sense of straightness, while on the curvy surface small triangular pattern rotating clockwise with a overall point attractor, adding on curviness of that surface.

Waffles are made with the idea of contrast as well. 2 sides are parallel at the bottom of the structure, and seperating as it grows towads thhe top.


Week Four

Laser Cutting

Due to the nature of large blocks, unrolling has to be done seperately for some of the panels, which gives weaker inter-panel bond, affecting the overall coherency of the surface. Panels on the 2D surface have to be seperated to avoid overlapping. Unnecessary tabs are removed which had made the model making much easier. Waffle is laid out with index, yet still confusing and have to refer to the 3D model in Rhino when making the model. Some parts are combined to minimise the lines that the laser needs to cut. This arrangement could be further improved.

Week Five

Since circular is always a good contrast to rectangular shape, and similar contrast has been tested in the first task, this second task would stick to the same idea as well. The scripts are simply geometies with certain circularity, from simple sphere to cone and cylinders. Cylinder is chozen as the final design as it not only provides the contrast with the external cube, but also has the contrast internally as it has both flat parallel surfaces and a circular surface. A simple piont attractor is used for the grid.


Week Five


The model shows a section of a cube, cut by a serie of rotated cylinders with a point attractor. The section is cut with 2 cuboids, demonstrating the shape of cylinders wich creates the slopy solids and circular cuts. Due to the use of a single point attractor, the cylinders perform a strong directionality, which is hence transformed into the structure. With the hight smaller than its radius, a thin layer of solid is left after boolean. In reality, the thin solid layer could be easily transformed into cantilevers which provide shades, whereas the smaller cuts on the surface of the solid could be opennings such as windows and doors. Solid could also be thought as spaces, or boundary of internal spaces. For the choice of section, the attempt is to have some acute angles as I believe the sharp shape would be a good contrast to the smooth internal cuts. It is also deeply cut for an overal permeability of the structure.


Week Six Task 01

Task 01 Matrix From having a straight and a curvy surface, to constructing a bounding grid instead of a simple point or curve attractor, the final design is made of three panels from 2D pattern to flat and hollow 3D to a bulky solid. The solids would enhance the staightness while the pattern flows through the curvy surface, thus the contrast between two side are emphasized.

Task 02 Matrix The final structure performs a contrast between sharpness and smoothness, just like the contrast between the two surfaces in task 1. This is the main reason for choosing it as the final design.


Week Six

Final Isometric Views




Individual panels. Made through different ways to see the difference in unrolling.

2 grids to bound the panels. Instead of offsetting, the bounding grid is manually plotted.

The Panels beform replacement. The diamond shapes are forming a perpendicular plane. The light and shadow are interesting.


The unwanted panels are manually removed and the rest are combined together.
