Abstract

See full text

Methods for CAD operations and corresponding systems (2800) and computer-readable mediums (2826) are disclosed herein. A method includes receiving (502) a model (600) of a part to be manufactured, wherein the model includes a plurality of original faces (102, 104, 106, 112, 114). The method includes classifying (510) each face in model according to a relative face curvature according to classifications that include at least a high-curvature classification (702). The method includes classifying (514) any sliver faces (102, 104, 106, 112, 114) and narrow blend faces (402, 404, 406, 408) of the plurality of faces. The method includes merging (516) contiguous faces (702) in each classification. The method includes detecting (518) special faces (1002, 1012) of the plurality of faces. The method includes restoring (520) original faces in the high-curvature classification except for the special faces (1002, 1012). The method includes processing (522) shared edges of the restored original faces to produce merged faces (802). The method includes merging together (524) any merged faces that produce a locally narrow face (302) or an isthmus (202). The method includes storing (526) a modified model of the part to be manufactured.
