Oh and here's the specifics of the software.

I'm working on a home addition. The existing house has a 6' crawlspace with a ceiling that's 24" above ground. The front entry porch is four steps up. The lot slopes down towards the back, and the back entry has five and a half steps. The garage is a slab on grade. I have an elevation line at the front, as the street is higher. Then I have an elevation region around the house and another around the garage. I just can't get this right. I've tried changing the ceiling, floor, elevation and I'm just struggling to sort this out. Any tips would be appreciated.
