Commands to support cavity & core division creation on Fusion360.

This command supports cavity and core division of thin-walled solids.In V1 to V3, if there was a hole in a solid, the hole part was deleted using the hole deletion command, but in V4, if there was a hole, the solid in the part that would become the hole was generated as an auxiliary solid, and the cavity and core were deleted. After dividing, connect the auxiliary solids to create the shape of the hole.
