Draft

The draft feature is commonly understood with respect to mould tools.  It will add or subtract material to a group of edges to the set draft angle.

4 elements:

 

 

1. Draft surfaces – those surfaces to which material will be added or subtracted
2. Draft hinges – the edges about which the surfaces will rotate – these do not have to be adjacent to the draft surfaces
3. Pull direction – in the above scenario, either the chosen edge or the bottom surface indicates the zero degrees vector – vertical
4. Draft angle
