Removes the last inner surface of this boundary-representation solid. If there are no inner surfaces in this solid, this method will return None.

Return type:

FMESurface or None


The last inner surface of the BRepSolid or none. Note: This method returns a terminal geometry type of the FMESurface; i.e. one of the leaf classes in the FMESurface inheritance graph. For example, a FMEFace is returned if the geometry truly is a face.
