Two Level Foundation

[gcapwell]

This is my first attempt at using Suite 7.0. I have created the exterior walls to my home, and I believe the next step is to create my foundation. The problem is one half of my house is on peirs 4 feet off the ground, and the other half is on a floating slab. How do I create the foundations at two levels. The next problem will be connecting the two levels with a semi-circular staircase! Any help is appreciated.
