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.
