- A model complete with mass properties,
- Supporting calculations (i.e. a spreadsheet that shows how the drive speed or lifting force was calculated)
- A description of what the module does.
- Drawings for all custom or customized components, and
- A full Bill of Materials (BOM) with material price estimate (and ideally fabrication time estimate)
If one or more items is missing, then a CAD model is Level 3 (Basic CAD).
