Last week I utilized grasshopper as a generative design tool in place of Catia. This week I implemented Catia's 'powercopies'. Powercopies are powerful and more flexible then I first expected; also they provide a different visualization of constraints. Unlike grasshopper Catia shows the constraints in a very organized and clear method. This allows super precise surgical changes which can trickle through the design.
This assignment shows folded out shapes which can be used as a template for fabrication purposes.
The first step was to create a framework, ie. one sketch with multiple constraints where separate parts can be plugged in.
This particular framework use two points to allow itself to stretch and change.
One a framework was established a grid of 9 points was created and offset from the original framework (this is where the fabrication cut outs will be shown).
The next step was rather brilliant, it establishes a z-axis for another point which is the foundation for the physical geometry. This sketch was created in a new geometric set.
The framework outside of the sketch.
The next level of framework, is for the surface geometry.
The geometry created.
The geometry is join, then 'unfolded', and then referenced to the secondary (offset) grid.
Powercopies used to form an assembly.
The entire assemblies height modified by the changing the z-axis.
The entire assemblies shaped modified by changing the base framework sketch.
The change updated and the following assembly geometry.
