Rotate the geometry part, containing only edges and faces (not solids or closed regions), around an axis by a specified angle.

Note: The spin operation is applied separately to each of the selected geometry parts.
The spin operator is a rotational sweep operation. Lines become faces and faces become volumes. For surface bodies, the body must have a single boundary which does not close on itself and no edge may be attached to more than two faces.
