I know this thread is old but I just started playing TS3 a few weeks ago. I started playing and using already built homes and I decided to try and build a home myself. Finally, after spending several days building the perfect home for my sim, I realized that I needed more space and I was elated to find your tutorial! I followed your instructions step-by-step (I don't think I missed anything) and I came out with a perfect set of stairs! When I went into Live Mode to test them out, they don't work at all. A thought bubble comes up that says she can't use the stairs. I read on other posts that sometimes this happens but they can use the stairs coming up. So I used the moveobjects cheat to place her in the basement but she can't come up the steps either. The only issue I can think of is I used custom stairs (which I have placed in my house elsewhere and they work fine).
Can you offer any help? I will be so disapointed if I have to build another house for my sims :(
