Critical Reading: Kolerevic B. 2003. Architecture in the Digital Age

Kolerevic described three fundamental types 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: 1. Subtractive Fabrication- Is a technique by removing a specific part from a solid. This technique access by electronic and mechanical processes. 2. Additive Fabrication- Is a technique by adding materials into the layers. The process requires separating a 3D digital model into 2D dimensions. Then the machines will recognize the information from different layers in order to produce physical products. 3. Formative Fabrication- Is a technique via by mechanical forces, steam and heat to reform the shape of an object. Computer numeric controlled fabrication allows the physical outcome is more precise and accurate, meanwhile having less error. Similar to prefabrication, it requires less time and cost to produce. The potential of this is allowing the designers to produce different iterations of complex geometries or surfaces. Therefore, the designers are able to produce interesting designs more efficiently and produce the outcome at a faster rate.

SURFACE AND WAFFLE STRUCTURE Surface Creation

The script starts with a cube shape as a bounding box and measure in 150x150x150cm. Then, the command of Deconstructed Brep which breaks the curve into edges and divided into coordinate points to form a line. The surfaces are created based on the line (connect by two points(Starting point and Ending point) and using command loft) By using this script, it supports me to understand the developed surface and enable to produce different iteration of surfaces. Therefore, I have down different trials by changing the number of two points to play around with the surface.

The first iteration is trying to create a connection between two surfaces, but two surfaces are dimensioned differently. Eventually, It created a shape of wings in active mode.

The second iteration is to separate the two surfaces to focus its individual. Therefore, it allows each surface to have its characteristic. For instance, the shape, orientation and dimension are different.

SURFACE AND WAFFLE STRUCTURE Surface Creation

The third iteration follows the same concept of the first iteration, hence create a relationship between two surfaces. However, two surfaces are not joined together. I have attempted to use the different height of the two surfaces. One of the surface I have maximized the value, whereas the other surface I keep as low value.

The fourth iteration which is my final surfaces of design. The two surfaces have a sufficient gap and twisted into a different direction. The dimension of the two surfaces is on a similar scale, which creates a concept of the mirror. The pathway from narrow to wide which create space more interesting.

Isometric View

The edge points between two surfaces have corresponded to each other. The points are of the edges are diagonally opposite to form a trapezium shape. But, the two entrances are shaped opposite. Therefore, it creates curves for both sides, while having slope circulate path.

The waffle structure is created based on the two surface panel, hence itâ&#x20AC;&#x2122;s like a substructure to hold and support the two surfaces. There are 6 horizontal (dotted line) panels joint with 7 vertical panels.

SURFACE AND WAFFLE STRUCTURE Laser Cutting

For the surfaces I have used the command of Unrollptsrf to create the flat surface and use pttabs (2mm) to create tabs around the surface, which allows me to fold it to form as a physical model. Moving on, the waffle strips laser cut was created by make 2d in grasshopper. The black line represents cut and the red line indicates the etch.

SURFACE AND WAFFLE STRUCTURE Matrix and Possibilities

Refer to the page 8 matrix diagrams, these are the process for exploring the final design which shown on page 9. The first row represents the process of exploring different iteration surfaces which are also shown in between page 4 and page 5. This allows me to understand how to manipulate the surface in an appropriate way and also generate a relationship between the two surfaces. Moving on, the second row demonstrates the uses of attraction point. I have applied two of these command in grasshopper, which allows me to change the orientation of the points. Lastly, the third row indicates the pattern and geometry for the two surfaces. Each individual module has a two pyramids shape which shares in the same rectangle base. I have created multiple attempts for the design by creating 2d and 3d geometries to form a sequence of the pattern. The 2d geometries are simply extruded lower or equal to 10mm (height) and everything else that above represents the 3d function. Scale 1:3 @A4 (drawning in milimeters)

SURFACE AND WAFFLE STRUCTURE Photography of Model

This is my physical model for Task A. The concept of this design is showing two different ideas, which are random and group. This is inspired by the planning of city and suburb. Therefore, random represent the city, as most buildings in the city are distributed in different areas. Whereas suburb, all the residential house are separated and planed evenly with the site. As a result, it regards as a group function. For the random areas, all the modules are placed differently on the attached surface, the tall modules represent the tall establishment, while the flat (almost flat) represents the field. Moving on to the concept of the group, I separate the tall modules into four regions and representing residential houses. The lower modules which form a plus (+) sign, it indicates as the road or field. Out of these two concepts, I personally prefer the concept of the group, hence it distributed evenly of areas and this perhaps this concept can also be carried to task B.

This script is only for creating sphereical script.

I have used two scripts for creating the design for the parametric model, both scripts are majority the same, except for the box centroid. The first row of the script is for different geometry and the second script just for spheres.

SOLID AND VOID Surface Creation

The model shown in figure 1 is the first model that I have attempted. It is simply constructed by using the sphere to create. The idea of this model is trying to create a separation between two areas in open spaces.

The second model I have considered the idea of private space. Therefore, I have added an extra roof on the top of the model and the inner space are all circulated. Moreover, all the inner spaces are connected to each other which follows an idea of apartment rooms, hence the small circle open gaps represent door or entrance.

The last model demonstrated a more secure private space, as the internal space is smaller compared to the second model on page 13. I have applied two geometries in this model. Therefore, internal panels will have a different outcome.

The third model shows it above is my third design. The design is inspired by the Le Corbusier 5 points. This model demonstrates the idea of the free plan, pilots and roof garden. Also, I have considered the concept of public and private in this model. Therefore, I have divided them into two sections, the ground floor can be a private area, whereas the roof is more like a public area. Scale 1:1 @A4 (drawning in milimeters)

SOLID AND VOID Isometric view

Iâ&#x20AC;&#x2122;ve select my third model for the isometric section, hence it has more interesting of space contrast. I have used the hexagon volume as the boolean geometric. The model itself should be structured in a 150x150x150 cube. However, all the cutoff of geometries is all present inside the cube. Therefore, I have decided to cut part of it, and it shows on the left with a rectangle shape. The shape of the model looks like an apartment with different stories, while each layer has its characteristic. Because the way of the cutoff is different, hence it creates a different experience of space, which can be exploring further. I like the idea of having various openings since it can be used for a different purpose. Also, it allows people to have a variety of interaction in each fragment.

Task B Matrix

The first row of the matrix is focusing on the distribution between the 3x3x3 grids. I have tried multiple iterations of approach by changing the direction of the point attractor in grasshopper. The second row is creating geometries and manipulating them into different locations. This section has the same prototype shape and adjusts the size for various trials.The last row is to demonstrate the different uses of geometry. I have attempted using a cylinder, rectangle, hexagon shape. Also, combining two different geometries.

Photography of Model

Out of all the 3d print models, I have select iteration 2 as my final. Compare to all the iterations that I have designed, iteration 2 has overweight the rests, hence it covers the other two iterations characteristic. Iteration 1 has a concept is playing around with spaces, the internal spaces are separated by the wall however you can still view the spaces inside via the circle hole. This concept has also applied to the iteration2, hence it separated into two areas, the roof, and ground, but people in the rood or groud can still see each other. Moving on, the idea of private space seeing in iteration 3 has also applied in iteration 2, hence the two separations of areas can be treated as private spaces. In an extent, it also can be regarded as public space. Moreover, the interesting space cut out of the iteration 2 has added extra geometry into the models. Lastly, it relates to some of the Le Corbusier concepts of 5 points, which are Free plan, Pilotis, Roof Garden and Free design of Facade.
