I am trying to use rebuild on a ‘‘closed solid polysurface’’ but it does not let me select the object.

-It works fine onany other objects.

Rebuild is not predestined to work with Polysurface, because every surface has its own UV-Layout and Degree
Try _Explode first and rebuild

Be aware that Rebuild can change the shape of edges. After rebuilding the individual surfaces some of the edges may be out of tolerance which prevents joining. MatchSrf can be used to bring edges together.

If you want to increase the number of control points then consider using InsertKnot. It does not change the shape.
