Creating Draft Features

Taper or draft often needs to be applied to part faces so the part can be extracted from the mold in which it is manufactured. You can create draft features in three different ways:

• The Fixed Edge method works by selecting a pull direction and then selecting the faces/edges upon which to apply the draft.
• The Fixed Plane method works by selecting a fixed face and applying drafts to the faces intersecting it.
• The Parting Line method works by selecting a sketch to define the parting line where the top and bottom halves of a mold form would meet.

To explore the Fixed Edge and Fixed Plane methods, open the file called mi_19a_046.ipt in the Chapter 19 directory of the Mastering Inventor 2012 folder, and then follow these steps ...
