Design of a CAD Model

Example: Design a Control Mesh for a Catmull-Clark Subdivision Surface;
it should be simple, highly symmetrical, produce a nice, smooth surface,
and be suitably parametrized to do future studies in energy minimization...
e.g. -- a Genus-4 surface.

This is a Multi-stage Design Process:

  1. Understanding the Task
  2. Initial Inspiration (Mental Image)

  3. Clear Concept (Sketch, Mock-up, Draft Code, ...)
  4. Possibly go back to #2

  5. Accounting for All Specifications
  6. Possibly go back to #3
  7. Precise Part Description (CAD file)
  8. Document Your Design
