Abstract
Methods for identifying chamfers in CAD models and corresponding systems and computer-readable mediums. A method includes applying filters to a set of candidate chamfers, the candidate chamfers identified from a plurality of faces in a CAD model, to produce filtered candidate chamfers. The method includes generating maximal chains of the candidate chamfers and grouping conflicting chains from the maximal chains to produce chain groups. The method includes determining best conflicting chains from the chain groups, including designating at least one of the chain groups as accepted. The method includes storing the faces of the CAD model that correspond to the accepted chain group as realistic chamfers.
