ABSTRACT:
In a method for blending an edge of a geometric object in a computer-aided design (CAD) system, a user can select an edge which is to be blended as well as the size of the blend portion. The size of the blend portion can be selected, for example, by entering a desired blend radius into the CAD system. The CAD system calculates the blended object comprising the blend portion and the remaining parts of the original object. The intersections of the blend surface with the object are calculated and it is determined which edges and faces of the original object are deleted by the blending operation. The method is capable of performing blending operations wherein an arbitrary number of edges and faces are removed from the object. The method can also be used for blending an edge with a variable radius and for chamfering the edge.
