Expensive, work intensive and not very bright.

Re-make: Lets start with fabrication.

1: Fabrication Design - make it cheap and fast.

2: Design Input - make it available.

Master curves

Density

Sheet width

End design

Nesting

G-code for CNC

Assembly coding

Structural model

3D Visualization

3: Design Outputs - what do we need?

2: Automate - make it live.
