I need to create a monolithic slab w/ no stem wall

[binkpear]

I need to create a monolithic slab with a deepened perimeter with NO stem wall. I can not seem to get rid of the stem wall...am I missing something obvious?

When you built the foundation, did you chooser "mono slab" in the "build foundation" dialog?  If this is what you did, and you are still getting stem walls, then you might want to post the plan because I can't think of a good reason why that would happen.
