The CreateRegions command replaces a non-manifold polysurface with all solid manifold regions defined by the surfaces of the input.

This command is typically used after the NonmanifoldMerge command.

Two spheres and a plane (left), after NonmanifoldMerge (middle), exploded view after CreateRegions (right).

Select a polysurface whose surfaces bound one or more solid regions in space. The command will replace this with the solid polysurfaces that form the regions.
