I laid out my ground floor, and meant to duplicate them to the basement level, but I forgot to do it until after I had doors and windows in place. At that point I shut off visibilty for everything but the wall, and duplicated them to the basement location.
Now where ever doors were, there's no base trim. I've tried to add the trim, or replace the walls individually with another like wall, but it won't let me add the trim where missing.
UPDATE!!
Never mind......I just deleted the 5 sections, and drew a new wall in their place and all is fine.
