About the Variable Pull Direction Draft Feature
The draft angles of a Variable Pull Direction Draft feature can be set at selected points:
At the end points of the draft edges or curves.
At datum points that lie on the draft edges or curves.
Along the draft surface.
You can also set the draft hinge in a separate position from the pull direction reference surface.
A good example of a variable pull direction draft is the design of an automobile tire. You can design the treads to become narrower as they become deeper, and you can apply deeper drafts from the same reference surface as the shallower drafts.
You can apply a Variable Pull Direction Draft to either solid surfaces or quilt surfaces but not a combination of both. The first selected surface determines the type of additional surfaces to which you can apply the feature.
