PARTITIONING 3D CAD MODEL

A computer-implemented method for partitioning a computer-aided design 3D model of a mechanical part. The method including obtaining a volumetric B-Rep of the CAD 3D model, detecting one or more ribbons of the volumetric B-Rep, ranking the one or more detected ribbons based on one or more geometrica...

Summary:A computer-implemented method for partitioning a computer-aided design 3D model of a mechanical part. The method including obtaining a volumetric B-Rep of the CAD 3D model, detecting one or more ribbons of the volumetric B-Rep, ranking the one or more detected ribbons based on one or more geometrical criteria that are associated with each of the one or more detected ribbons, and selecting successively following the ranking each of the ranked one or more detected ribbons. The method further comprises, for each selected ribbons partitioning the volumetric B-Rep of CAD 3D model using a splitting method associated with the geometrical criteria of the selected ribbon, thereby obtaining two or more partitions, and for each obtained partition, determining whether the partition represents a sweepable volume.
