Have been working up detailed retirement house plans (Pro 2012). Somewhere along the way I have lost individual room definitions for the first floor. Click on a first floor room and all the rooms light up. Even tried deleting a door to a bedroom and fully enclosed rooms are not enclosed......the whole floor plan inside the exterior walls lights up. This is a problem in defining individual room ceilings and floor coverings. Have searched the forum high and low and have not found anything. Help would be greatly appreciated. Thanks.
