OK, I think the Sims 3 Fairy visited me because I went in to do a screen capture for you and I removed every roof, working or not, and I was going to take one screen capture without any roof in place and then I was going to take one of the outcrop roof I was trying to do to show you what has been happening. Mind you, this has happened with 3 different houses. Today, I went to put the outcrop roof on again for the screen shot and it worked!!!! I have no idea why and now I can't get it not to work. I even went back to the other two houses I did and added outcrops and it worked?!?!
I'll be documenting what I do in the future in case it should happen again. This is just bizarre...I know software can be glitchy, or I can be a little thick at times, but I've seriously never been able to do it. And I did try a lot!
Thank you for looking into it for me though. I appreciate it!! I'm thrilled it works now
Problem solved!
