I am having trouble adding a basement.
I started with the first floor, then added a second floor. Now I want to add a walkout basement. I found the article on setting all the elevation data but I cannot figure out how to add the basement itself. It seems like I can only "build up" rather than down. Surely there is a way to add a basement below the first floor. I imagine I'm missing a simple solution--I just downloaded this software yesterday so I'm still learning a lot. Anyone have any insight? Thanks a lot!
