Sweeping a profile along small circular arcs of a path

Abstract:

A method, apparatus, article of manufacture, and computer program product provide the ability to sweep a profile along a circular arc of a path. A sweep operation to sweep a profile along an arc of a path is initialized in a CAD application. For each path segment (in the path) that is circular, a determination is made regarding whether the profile crosses an axis of revolution of the circular path segment at a start position of the circular path segment. The profile that crosses the axis of revolution of the circular path segment is trimmed. The trimmed profile and an association with the circular path segment having the axis of revolution that is crossed by the trimmed profile are stored. A selective union operation that joins the solid bodies from the trimmed profiles is performed.
