Brief
Assignment One utilises past student projects as a platform from which to develop students’ understanding of parametric modelling tools and digital fabrication processes. Each student needs to select one project from previous iterations of DDA and identify a key theme or concern using existing student diagrams, grasshopper definitions and scripts. Grasshopper definitions and hobbyist code are notoriously difficult to extend and share, and a key objective of this assignment will be to utilise the Diagramming Tool as a means of interpreting and documenting previous and future work. Furthermore, as many students undertaking the subject begin with little background knowledge or technical skills, all past projects exhibit potential to be refined and improved:
1) As a technical exercise in optimising, documenting and packaging code
2) As a building block to be combined with other parametric techniques or geometry
3) By considering different material applications or fabrication techniques
Task
Design a lightweight structure for the South-Eastern corner of the Old Arts Building (the temporary home for the architecture faculty). The design should respond to changing light conditions across the facade and perform as an expressive gateway to the University, and for Swanston and Grattan st pedestrian access.
Design Intent
Similar idea developed by IwamotoScott (2005), the idea is to design operable screen that combines ideas from origami and digital production, focusing in particular on creating a flexible and environmental resposive system.
Conceived as curtain of the building, The Sizes/Apertures of the opening of this screen are determined by using attractors point.
- The modules that make up the screen are designed so that they hold two distinct shapes: In and out. All the modules are bolted together similar to the method done for Huyghe + Le Corbusier Puppet Theatre, MOS, 2004.
- All the modules are easily assembled and disassembled .
Pattern
Form Making Process
1) Set a surface in Rhino. Then divide the surface along U & V coordinate
2) Get all the corner points out of the surface. Use ‘List Item’ to extract corner points from each subsurface
3) Use curve analysis tool, Evaluate Curve to find the mid-point. Set parameter 't' to 0.5
4) Create two sets of Lines
5) Create an attractor point in rhino and assigned it in grasshopper to control component variables. I placed the attrator point at the lower level of the building as shown in the blue circle.
6) Evaluate Variable Points Between Corner & Center
7) Create surfaces by connecting all points
8) Make a copy of definition to create outer skin/layer. For this layer, find the nearest point of the surface to move the points towards normal direction. And copy it to other side of triangle
Fabrication
For this simple exercise it took me 3 hours to assemble all the parts. For material I used Ivory Card because of its lightweight and strength.
