Hi Michael,
Thanks for replying so quickly. Actually, I have more symptoms. I did try to separate, then join. Same result. When I exported the model to a STEP file, then opened it, it was not joined, all of the surfaces were separate. I don't know if that tells you anything. I guess I will try joining everything together again surface by surface.
