How to apply several materials to several surface in catia?

If you build a cube in one body in a CATPart it is not possible that each face has a different material. If "extract" the surfaces in GSD, you will get six surfaces and give each a different colour.

If you get solids, every body has ONE material. If you need different matierials in one PART, you must insert different BODYs, each for one material.
Surfaces are easy, just drag and drop the material at the surface. one material per surface.

thanks a lot problem solved
