About Variable Draft
When you first define a Draft feature, a constant draft angle is applied to the whole draft surface. This is called Constant draft. An example of Constant draft is shown in the following illustration.
1. Draft surface
2. Draft hinge (sketched curve)
3. Surface selected to define Pull Direction
4. Draft angle
In Variable draft, you apply a variable draft angle at various control points along the draft surface:
• If the draft hinge is a curve, the angle control points lie on the draft hinge.
• If the draft hinge is a plane or quilt, the angle control points lie on the contour of the draft surface.
An example of Variable draft is shown in the next illustration.
