Taperadding transformations on a shape. The resulting shape is constructed by defining one face to be tapered after another one, as well as the geometric properties of their tapered transformation. Each tapered transformation is propagated along the series of faces which are tangential to one another and which contains the face to be tapered. This algorithm is useful in the construction of molds or dies. It facilitates the removal of the article being produced. A DraftAngle object provides a framework for: More...
