Draft Options

The Draft function is pretty straight forward as there is not many options to this feature. To create draft angle, first select the Normal Face (highlighted in pink on picture below). The Normal face is the surface perpendicular to the draft face. Next select the Surfaces to Draft (highlighted in blue on picture below).

After adding Draft angle

Note that during setting up the draft feature, there is small arrow pointing upward at the Normal face. This arrow indicates the pulling direction, where the top face would become the smaller cross section area, and the lower face would become the bigger cross section area. Should this arrow is pointing downwards, the end result would looks like an inverted pyramid.
