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 construction of complex geometries is achievable with the use of CNC fabrication. CNC subtractive, addictive and formative fabrication techniques allow for more opportunities of geometric computation and constructability. Subtractive Fabrication is the removal of a specified volume of a material form with the use of a multi axis milling. The variety of shapes that can be form is limited due to the axial constraint of the multi-axis milling machine. The limitation of the form decreases as more axis is added to the milling machine. Addictive Fabrication is the addition of materials in layers to produce a layered form. However, the production is limited by size. Formative Fabrication is the reshaping or deformation of a surface through the use heat or steam applied on a material to get the desired shape.

Surface Creation

Iteration 1

Iteration 2

Iteration 3

Iteration 4

The iterations were created by lofting 2 different lines in a 150 X 150 X 150 box. These lines are created by joining points on the edges of the box. The seletion of points can be altered by changing the number slider. For iteration 3, the surface is created by lofting 3 lines together. All the lofted surfaces are then shifting and rotated to get positioning which seemed to create an interesting internal space and entry.

Week Four Panels & Waffle

Mixture of 3D and 2D panelling. The 3D panels are attracted in a specific direation to only show openess on one side of the structure. With the twisted design of the waffle, hollow cut outs of the 2D panels allow light to pass through the panel surface from all directions.

Waffle structure is built from 2 loft surfaces. Due to the twisted nature of the loft surfaces, the vertical components had to be scripted outside of the horizontal components. The placement of the loft surfaces created a wider gap on one side of the waffle structure and a smaller gap on the opposite side.

Week Four

Laser Cutting

Due to the twisted nature of the loft surfaces, meshtoNURBS created multiple small triangles in a single panel shape. This caused a problem when unrolled. Therefore, it took time to break up the intersecting unrolls.

Panel Surface

To save lasercutting time (save money as well), I joined straight lines together. It is important to organise these panels properly to avoid mistakes when trying to construct the physical model.

Iteration 3

Iteration 4

Different attractors were used to manipulate the grid and shift the centroids of the objects within the box. A custom geometry script was created so that I could input my own geometrc shapes. For iteration 4, I explored with Lunchbox and used a plactomic icosahedron shape. I combinded it with weaverbirdâ&#x20AC;&#x2122;s stellate to dip the lunchbox shape within.

Week Five

Isometric

I chose iteration 3 as the scaling and distribution of the geometry created interesting intersections within the box. With the geomerty I used to boolean, it created an intersecting spiral tube through the center of the boolean model. It also created leveled interior spaces, which could be used as gathering spaces. The spiral tube connects to all enclosed spaces, allowing for accessibility within the model. I sectioned the boolean model in a way which created â&#x20AC;&#x2DC;windowâ&#x20AC;&#x2122; openings above the base level of the model and only allowing one point of entry through the boolean model.

Task 01 Matrix I explored with different attractors such as the point and curve attractor. I designed simple 3D shapes to complement the complex loft surfaces. I chose iteration 2 as I prefered the interior space created by the loft space. I knew that constructing the physical model would be a challenge due to its twisted nature.

After receiving the physical model, it gave me a different perspective of how I wanted the threshold and circulation to be through this boolean model. Playing around with the oreintation of the physical model gave a better representation of howthe interior space could like as compared to messing around with it in Rhino.
