Brown Tiger, you are correct, sir.

thanks glennw! I had not been able to resolve the double thick wall ends at the porch and used cad lines to mark what I needed to go back to . I just inserted a  new turned  short  exterior wall at both interior ends and was able to fill the wall ends and that resolved the problem. Now that I think of it the way I drew that  was probably not the right way to approach it anyway.

Also, thanks KBird. I did check that as it sounded somewhat familiar. I have to relearn every time i use the program so I go around clicking this and that to remind myself what happens- I was afraid I had inadvertently clicked something that made a huge change. As simple as the plan looks, the house is very complicated and I should have started something simpler. 

I can open rooms again. What a relief!

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?
