This page provides all the content used during the CAST Workshop (COFA, Sydney, July 2012)
SEMINAR 1 – RHINO INTRODUCTION
This seminar will provide participants with a general introduction to the Rhino 3D including interface, navigation and toolbars. The seminar will focus upon introducing the procedures within Rhino needed to understand the Grasshopper operations utilised during the workshop.
SEMINAR 2 – GRASSHOPPER INTRODUCTION
Introduction to the grasshopper toolbars, context menus and icons. Learn how to use parameter components to begin working with Rhino geometry in Grasshopper. Generate a parametric loft from referenced geometry in Rhino, and from points created in grasshopper. Use Panels to observe how Grasshopper components process inputs and outputs, and to document the definitions workflow and learning process.
SEMINAR 3 – ASSOCIATION, SPACE, MAPPING AND FUNCTIONS
Modelling parametrically enables the designer to explicitly inform the geometry that is generated. Explicit information can also be extracted from objects higher up the data flow. The seminar will present various approaches to associating these parameters (points, images, graphs etc) with the properties of another – in this case finally resulting in vector lines used for fabrication. This allows designs to become responsive to conditions: site conditions (body curvature), required performance (rigidity/flexibility for movement), intended viewing angles, fabrication constraints etc.

SEMINAR 4 – SURFACE FABRICATION
These clusters will be used to create the distortion surface for the silicone and resin moulds.
This cluster component takes a surface and divides in perpendicular directions. The intersections of these sections are then found and then notches are subtracted so that the sections can be joined together.
This cluster component takes a solid geometry and divides it in perpendicular directions. The intersections of these sections are then found and then notches are subtracted so that the sections can be joined together.
This tutorial introduces the FabLayout cluster component. The component orients geometry to a grid of points for fabrication.
This cluster component adds tags for documentation and fabrication.
Fabrication Combination Cluster – This cluster will be added during the Cast Workshop
LASER CUTTING FABRICATION SETUP DOCUMENTATION
SEMINAR 5 – PATTERN FABRICATION
SEMINAR 6 – DATA STRUCTURES
Within grasshopper data is stored in a structured system of items, lists and trees with path information which shows a particular item’s location. To apply an algorithm to a single or collection of items we must organise this structure appropriately.
5.3 – Label a 3D model using text tags
5.4 – Orient objects to a grid
5.5 – Draw points through a grid of points in two directions
5.6 – Interpolate between a list of polylines
SEMINAR 7 – FORMAL SIMULATIONS
One of the areas of research for the workshop was to explore methods to fabricate the patterned and complex doubly curved surfaces of the virtual world. This seminar will be based around demonstrations of a workflow developed for the workshop which employs a particle based physics simulation which is used to distort an input piece of geometry in a way that is replicatable in a fabrication process.
