Need help illustrating foundation on a sloped topo solid

[vanderloo5]

I just loaded up Revit 2025 and am getting ready to start a new residential custom home on a very sloped lot. I was hoping someone can steer me towards some learning material for illustrating foundation footings, stemwalls, and cripple walls up to the floor joists of the main level.
I was hoping to generate a topo solid from an autocad .dwg topo plan, (spot elevations), which I have also never done but it looks pretty easy.
The foundation and stemwalls will step up with the slope of the lot. I usually try to keep the 6" concrete stemwalls about a foot above grade and frame wood stud walls from there to the main floor. Footing sizes will vary as Engineering dictates.
But the back of the house main floor will be 8-10' above grade.

Thank You

What do you mean by "need help illustrating"? Do you mean you need help "modeling" stem walls and cripple walls?  If so, how so?  Walls are walls. Use Basic Walls. If you want to model the cripple wall framing members, then use Curtain Walls or Beam Systems.
