Simplifies the geometry and topology of 3d solid entities.
DmSimplify removes unnecessary edges and vertices, merges seam edges, and replaces the geometry of faces and edges by analytic surfaces and curves, if possible within the userspecified tolerance.
It is recommended to always run this command on imported 3d solid geometry.
