I have done something that makes it impossible to select individual rooms, but only on the first floor. When I click "select" anywhere on the plan, almost the entire plan- but not all- is shaded. I included a screen shot. When I open the object a "room specification" dialog opens but instead of the usual options, the only choices are "wall covering" and "materials." "General, Structure, Deck Molding" etc do not appear. I am still able to select individual components (wall, door,etc) but not rooms. Obviously this is limiting in completing the plan.
I do not have rooms locked in the display options. I do not have this problem with second floor and crawl space in the same plan.
I have looked at everything and cannot seem to find a solution- perhaps it has something to do with materials? Does anyone have an idea of how I can return this to normal operation for rooms?
