Abstract: A computer-implemented product including instructions embodied in a non-transitory computer read-able medium that, when executed by a processor, cause the processor to receive input selecting one of a plurality of faces of a boundary representation model of an object. The computer-implemented product may include further instructions to identify boundary edges of the model outside the one of the faces not separated from the one of the faces by an intervening concave or convex edge. The boundary edges may define a perimeter of a topological feature containing the one of the faces. The computer-implemented product may include further instructions to identify a set of the faces including the one of the faces contained by the perimeter and generate output highlighting the boundary edges and set of the faces of the topological feature.

Abstract: Methods to automatically recognize bevel features and bevel chains in inner bounding loops and outer bounding loops of walls and bends in sheet metal models or on solid models are disclosed, which may be used for computer aided design, manufacturing, DFX, costing, etc. Recognition methods of various types of bevels and classification of bevels as V-bevel, inverted V-bevel, Y-bevel, inverted Y-bevel, X-bevel, K-bevel, generic bevels and different types of vertex bevels are disclosed. Bevel chain recognition methods that assemble the same type of bevels into bevel chains and identify the bevel chains as tangential bevel chains, non-tangential bevel chains and mixed bevel chains based on the connectivity between the bevels are disclosed. Methods to generate bevel profiles that may be used for feature recreation, feature suppression, or tool path generation for cutting features for manufacturing are disclosed.
