DESIGNING A PART FEATURING A PROTRUSION OR A DEPRESSION

摘要

The invention notably relates to a computer-implemented method for designing, with a CAD system, a 3D modeled object representing a mechanical part. The method comprises providing a B-rep representing the mechanical part. The B-Rep has faces and edges. The method further comprises providing a first set of faces and a feature type. The feature type is either a depression feature type or a protrusion feature type. The method further comprises, automatically by the CAD system, recognizing a second set of faces within the first set of faces. The second set of faces represents a feature of the provided feature type. This constitutes an improved method for designing a mechanical part.
