How to build a foundation on two levels?

[jcaffee]

Draw your main living area with the floor height @ "0". Derive your foundation with the wall height set @ the actual ceiling height of the garage. (try 96")


Bisect the foundation plan with a foundation wall. Set the stem wall height on the side that is not the garage to 36" (or whatever your crawl space is). Set the room type for the garage as a garage. Add garage door. You end up like the attached.

Would this be the same process for designing our remodel of our split-level ranch home? Primary living area is above garage/family room floor and about 3' wider than ground floor. Length of both floors are the same. We're using HDPro, v10. Thanks.
