I created my concrete-stoop using foundation walls (Wall-Tools).........I needed 2 sections, an upper (stoop) and then a lower (stairs)......this was the only way I know how to create this because of a few things: Footings w/walls are needed (know elevation hgt.)
Roof/ceiling are not needed, however, I'm not sure of the best way draw a wrought-iron railing.....??
The stairs are dropped on top of the lower section, and then the stair material is changed to concrete.
I haven't figured out on how to draw a 6" trim piece on the left side (to mimic the right side)
Everything looks good in 3D except the few items I mentioned earlier.
