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 fabrication techniques listed in the reading are additive, subtractive and formative. While additive continuously build upward and adds in sections and shapes through layers like 3D printing does (where the head of the machine is controlled by x, y and z coordinates, subtractive is where volumes of a shape is etched into, heated, drilled or cut out to form a new shape. Examples of this includes laser cutting and CNC milling. Formative on the other hand uses Computer Numeric Controlled fabriaction to mold and reshape a volume. Because of its flexibility, formative options usually take up more complex shapes. The use of Computer Numeric Controlled fabrication helps designers to develop a more accurate structure or model through a “file-tofactory� process without the need to do physical technical drawings that is more accountable for human error. For complex structures, the existence of parametric modelling cuts down on time so more iterations can be made in ease more accurately.

Week Four Panels & Waffle

The two surfaces were made so that they resemble the feathers on that of a bird-wing. Some have triangular holes in them to thin out the design and bring attention to the areas of greatest contrast.

The waffle structure is made so that each corner decreases in size until it tapers into a point like shape. Because the corners of the surface was adjusted manually, the waffle extends mostly upwards instead of out, so that the vertical contour curves are not too intense.

Week Four

Laser Cutting

While preparing to laser cut, the unrolled nets for the panels had to have tabs put on there. Unnecessary tabs were then deleted to ensure there were no overlapping tabs. when submitting the laser cut file, cuts were to be outlined in black and put onto the respective cut layer, while the etches were put onto the etch layer in red.

Week Five

The base pyramid form was made on Grasshopper with the Mesh Pyramid tool from Weaverbird, but because it outputs as a mesh, it had to be baked into Rhino, then MeshtoNurb before referencing it back to the Grasshopper to make the edits. After adjusting the attractor points and scaling the cones, they were subtracted from the pyramid with Boolean Difference. Similarly, a diamond shape (developed from Grasshopper through the Lunchbox’s Platonic Octahedron option. Again, attractor points of both the grid and the diamonds were adjusted so that the booleaned result would have holes that both went through the pyramid at different points. The diamond shape was then rotated until some diamonds did not go completely through while others did to show variations in the form. Through this, the space within the structure changes and provide different perspectives as to what the form can provide in different

Week Five

Isometric

In this form, the rectangular cutout from the booleaned out diamond creates a sense of an extensive lookout or hallway if scaled up to the building size. The holes created from the bottom of the structure also mimck the shape of a cave. Both of these forms are quite open and “public”, but as it tapers toward the end, a more “private” like structure is created with a sense of closure. The final iteration was chosen by whichever booleaned shape showed a variety of interior wall shapes.

The contours have been adjusted bend inwards like that of a ribcage and lungs. This also provides the structure with a sense of movement and directs the eye into the structure rather than just skimming the surfaces.

The surface and panels combine so that parts of the surface is covered by the twisting day.

In the workshop, we were told to choose the edges of a cube and loft them together to make a surface. Instead I decided to control each corner of the surface manually in Grasshopper for more freedom in my surface forms. In terms of panels, it started off with a basic 2D grid split into two triangles diagonally. From there I extruded the base curves to a point. From there I decided to play around with the heights of the triangles until there was a clear distinction. Taking inspiration from the shape of bird wings, I manually placed the panels so that the tips of the “wing” are flatter with holes in the panels. This creates the illusion of lengthening and thinning of the “wing” as it reaches its tips). The panels were iterated to portray this concept in the contours twist around on the other side of the structure to transition a subtle manner. the eye between one surface to the other.

Task 02 Matrix Instead of purely point attractors or curve attractors, random attractor and a point attractor was used to alter the grid points for a directed grid that also spikes out in other directions. After the booleaned cones from the pyramid, I found the interiorTheshapes and the “lookout” idea quite interesting. However, the curved shapes didn’t impact the shadows cut out diamonds from the side of the pyramid reflect its own base shape. While the tips of the diamond as much so I opted for a sharper cut out shape: a diamond shape. taper to the end, those that reach to the other side and go straight through show a changing cross-sections.

The long extended shapes that cut through this solid encompasses the atmosphere of a hallway. It mimicks that of an extensive hallway to stretches out towards an exit. The length of these shapes give the solid a more enclosed, private feel even though it is exposed on the sides.

Appendix

Process

Adjusting the contours to have that triangular shape that bends inwards took far more steps in Grasshopper that I thought. But luckily with parametric design, I could adjust the values quickly and easily if I ever wanted to change.

The surfaces were adjusted manually so all four corners had their own individual points and there was no need for an attached Rhino file this way since everything has been done on Grasshopper.

11


Appendix Process

I made the diamond cut out shapes and the 6 sided pyramid through Grasshopper using both Weaverbird and Lunchbox.

Most panels were grouped into fives (each column). Because the laser printer cant etch on both sides, some etches had to be done on the opposite side. The problem was that the material would become incredibly thin after etching on both sides. Additionally, the etches split the ivory card in two so panels had to be stuck down twice sometimes.

The contours were build first to get a sense of the how big or small the module would be. It could be easily slotted in thanks to the cuts made on the contours.

Appendix

Process

There was a problem with some of the panels which have appeared to unroll the other way so the panels had to be retraced out by hand, cut, etched and folded inside out to accomodate for this problem. The picture shows the ones that had to re-done.

The panels were pieced together in columns before they were stuck onto the waffle.
