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 types of digital fabication are namely, additive methods, subtractive methods and transformative methods. Laser cutting and CNC milling are methods for subtractive digital fabrication. These machines use 3-5 axes in order to have control of the cutting tool that burns and carves away the areas that are to be deleted from a model. 3D Printing is one such example for Digital Fabrication. Complex designs are fabricated with the use of CNC Machinery for transfomative methods.

Surface Creation

Grasshopper script for creating surfaces

Surface 4

Surface 3

Surface 2

Surface 1

As seen in the above grasshopper script, 150mmx 150mm x 150mm bounding box was created before lofting the surface. The above image is the script in order to show the creation of one surface. The same steps were followed to create the second surface. The surfaces shown above are the different experiments in creating a surface. However, I chose the second surface iteration, as I was interested with the curves. I created this surface because I was inspired by Zaha Hadidâ&#x20AC;&#x2122;s use of curves seen in her Burnham Pavilion and therefore wanted to use that to articulater my surfaces. 3

Week Four Panels & Waffle

Pyramid Iterations were used to create the two panelling structures. Since the surface was already curved, I wanted to empasize the curves more by using these pyramid iterations. Since I wanted to create a wave like motion on my surfaces I increased the height of one panelling grid and lowered the height of the other. By increasing the height of the pyramid on one surface, I was able to achieve the major dynamics created within the surface. The pyramid used for the iteration was a slanted pyramid as seen by the green solid above. It was created on rhino and then referenced as a brep onto grasshopper.

The waffle structure is created to support the two surfaces. This too is a curved waffle structure.

Week Four

Laser Cutting

Unrolled panelling surfaces and flattened waffle structure set on the Fab Lab Laser cutting file. The clack layer is used for the cut lines and the red layer is for the etched lines. By doing this process it was easy during the physical model making process. 5

Week Five Boolean Operation Task 2 Grasshopper Script

Section cut out of the cube

Progress of Boolean surface from polysurface -> mesh-> mesh to nurb-> before making it 2d for the matrix. I selected this section of the cube as I was very interested with the morphed spheres. 7

Week Five

Isometric

The Isometric used is the South East view. I experimented this structure by only using the two mid points for the curve attraction. I did this do i could have control over where the spheres will be Booleaned. I intended on creating a space that would give way in order to manipulate with light. By doing this the outer rectilinear form is what is the threshold between the interior and exterior. The sphere openings are also a threshhold in which light passes through. Therefore, if this were a pavilion, the humans that would be in the interior at the bottom will experience the spacial and lighting qualitites within the structure. I intended on creating a structure, where the viewer would have a personal contact with the building as they pass through, as this structure is life like. I also manipulated it to look like a rectilinear structure from the exteriror, however when faced forward it takes up a completely different form. Therefore, itâ&#x20AC;&#x2122;s a kind of deception for the viewer and personal as the viewer would have to circulate 360 degrees in order to view the different features of the structure.

Task 01 Matrix The design matrix selected for task one is : - Lofts : 1.2 - Panelling Grid and Attractor point : 2.4 - Panelling : 3.3 I used these iterations in order tp create the best dynamic curve possible. Although I feel the waffle structure could have been improved. By doing this design, I noticed i had created the waffle structure and surface as two individual things instead of one as they had their own characteristics, which I found quite intriguing.

Trouble Shooting Problems from Task 1

When making the notches, I came across some problems where once of the contours were intersecting. Therefoe, in order to trouble shoot the intersecting contours I used â&#x20AC;&#x2DC;Cull Indexâ&#x20AC;&#x2122; on grasshopper.
