Keyed footing and foundation walls?

[SuperCAD]

I have two questions about Revit Architecture:

1. How can I make a keyed footing and keyed foundation wall?

2. How can I show the required rebar in the section of the foundation walls.

Thanks!

Really? No one else has encountered this before?

Found this on another blog:

For now, I've added a concrete beam (1'-4" w. x 1'-8" d.) along the lengths of my Retaining Wall Footings. Top of the beam is set at the bottom of the Ret. Wall Ftg. Because they are both of the same material, the section shows these two objects as joined

Use a wall reveal and cut out the key at the top of the footing. I draw the rebar in the 2D Section.33847
