The Shell command creates a hollowed out shell from a solid.

Shell only operates on simple, solid, manifold polysurfaces. These surfaces are removed and the remainder is offset inward, using the outer parts of the removed surfaces to join the inner and outer parts.


1. Select faces to remove from closed polysurface.

Leave at least one face unselected.

2. Press Enter when done

This step specifies which surfaces will be removed to make the shelled object.

The top surface of the cylinder was selected for removal.

Command-line option
