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)

CNC fabrication technologies of the digital age have allowed us to utilise a high degree of precision in fabrication and assembly. It is possible to produce series-manufactured, mathematically coherent but differentiated objects, as well as elaborate, precise and relatively cheap one off components. They allow the design of complex forms with surfaces of variable curvature, laying the foundation for a nonstandard mode of production. This is crucial for design development of the modern world, as a digital analysis and source of construction information. The three fundamental types of fabrication techniques involve non-contact scanning, two dimensional fabrication and mass customisation. Non-contact scanning is more efficient and accurate when scanning small scale objects, by precisely determining locations for the installation of various components. Two dimensional fabrication covers additive (incremental layering formation), subtractive (removing a volume of material from solids) and formative fabrication (heat and steam applied to deform and reshape). Mass customisation is economic and easy to achieve, as repetition challenges the notions of modernism and suggests the potential of a new, post-industrial standard based on the industrialised, creative capabilities of electronics rather than mechanics.


Week Three

Surface Creation






Exploring surface patternation in Grasshoper. Fig 1. Deconstructing a brep and manipulating a surface of one of the two panels (from fig.2) within a 150 x 150 parameter bounding box. Manipulation achieved through “list item” and creating variations with “divide curve” and lofting the four curves. Throughout this process, i envisioned the planes as enclosing walls creating different spacial qualities, Fig 2 & Fig 3. Experimenting with angled planes, creating wide openings of both overhead and ground space. Fig 4. & Fig 5. Using more dynamic shapes to close off the overhead openings and distorting the path of the ground space.


Week Four Panels & Waffle

Using the angles planes from Fig 2 of pg. 3. One side is characterised by pyramidal extrusions of slanting triangular pyramids, gradually decreasing in size towards the centre from one top corner. Towards the base the patternation expands and increases in size towards the opposite corner. This is created through the attractor points of (100,48,7). The other side is a straight angled plane with triangular perforations, with the same variation of patterning. In unison, the two panels can create a semi-enclosed space with small, varied openings allowing light to seep through and create geomteric shadows.

The waffle structure generated via the two planes creates a dynamic central space, open at one end and narrowing at the other. It appears to gradually flow towards one point from the wider opening, through its walls slanting towards one one side. The interior space generated can create the effect of a widening tunnel or mimick C-shaped walls which appear to be inviting when viewed from the exterior.


Week Four

Laser Cutting

Laser cutting was utilised for the waffle and panel nets. This was achieved through unrolling the surfaces via grasshopper, baking the curves created and exporting them to a laser cutting file. I changed certain vector lines to the appropraite layers i.e. etched lines for the interior folds of the nets, text tags and a few tabs. The rest of the vector lines were under a layer for cutting. Ultimately, i aimed to nest sheets efficiently to save space through aligning the waffle segments together and exploding the text. This process allowed a precise, clean job, limiting the amount of tape required and decreasing the cutting job time to a maximum. In this sense, i have learnt to optimise these machines to create precise facade patternation on a final model to limit constrains such as time, cost and file errors.


Week Five FIG 2




FIG 1. The manipulation of 3D grids and boolean processes in Rhino via scripting and designing boolean form. (creating bounds, listing items and constructing domains utilising a cylinder as the centroid of the volume.)The variations in the grids were manipulated with a design aim of producing porosity and permeability within the voulme to explore the notions of solid and void. FIG 2. Creating inter-space voids withn a volume FIG 3. Variations in a stepping, overlapping fprm (Reverse attractor) FIG 4. Consistant patterning within both structure and voids created FIG 5. Experiementing with more openings/poliferations in the volume


Week Five


This booleaned surface can be characterised by an interplay of radiating cylindrical forms and geometrical qualities of a cube. The interior spaces left behind from the intersecting curves and planes can be viewed as living space. The cylindrical and geometric elements of the structure opens up and defines the region, creating a form similar to that of an apartment block with semi-radial platforms. These extruded edge forms can create an interesting dynamic patterning of levels, perhaps serving as interactive space, balconies, look outs, etc. I specifically chose this iteration to develop and 3D print due to the harmonious interactions between the curved core alongside straighter elements forming the top and base. The volume address porosity and permeabiltiy through directing movement via its dynamic form of the levelled structure. At the base there are dips formed in the flat surface and two small openings created from the intersections of cylinders, mimicking the form of doors. I perceive traffic flow to shift across the base platform, through the “doors� and across the concaving, cylindrical levels.

Task 01 Matrix The matrix was an exploration of grid manipulation and surface patternation using Rhino and grasshoper. I specifically utilised index selection and various attractor point locations to create both straight, angled planes and curved forms. The panelling forms i modelled out consist of 2D triangular grids, extruded pyrmaids, panels with triangle poliferations and also a combination of both, which i have choen to develop (panel 3.4). I took an interest to the dynamic space created through the two simple planes, one curved and one slanted in a complementary formation.

Task 02 Matrix Grid 2 matrix was executed in a very similar manner to Task 01. I manipulated the grid through curve and point attractors, which allowed more dynamic forms of cylindrical distribution ahcieved through volume gravitational, series patterning and both curved and random attractors. I transformed the volume of cylinders through consistent scaling, morphing and reverse attracor, which i have choen to develop (panel 3.3.). It consists of a variation of cylindrical forms intersecting and overlapping at an upper corner, which sparked interest in how to address permeability by taking advantage of the spatial qualities of the curvatures.
