I'm getting anoyed at the new stairs now. They totally screwed it so it's impossible to make a good looking staircase inside. Before, in Sims 2, you could make the modular stairs as high or low as you wanted. But in Sims 3 it -has- to be either full size or from a foundation. I guess I'm hoping for some savior in shiny armor to come riding with some tips.

Check the building forum for tips on how to make modular stars using the CFE cheat.

you can make them as high or low as you want, if you build halfwalls as foundations for example.. but i totaly agree, because the sims 3 stairs are so disappointing to me -.- you don't have so many facilities.. but i'm still hoping for spiral stairs and elevators..

You can delete the under~parts of the stairs with the delete tool. Looks pretty good to me.

I don't have anything against them really to be honest. You had to have full size or off a foundation type of stairs in the sims 2 as well. It was the stage that changed that.

But yeah, try and find the CFE building cheats and then that will make the stairs more interesting.

I think though, at the moment we do have a lack of types of stairs.
