Is there anyone who knows how to get garage foundation walls to buck down to the underside of the garage slab automatically? The garage slab should be sitting ON the foundation at overhead doors, not butting up to it. This would be a great time saver to not have to adjust this CAD detail in every section of every plan. This is especially annoying if you're using an ICF foundation because it affects the 3D view. This is all easy to fix in 2D section views, and it doesn't really show up in 3D if you keep the slab and wall materials the same...but, if you're producing renderings for marketing materials, or sharing the model with customers, or engineers, or trades, etc., the model must be exact.
This thread probably ties in to other threads like sloping slabs, and decks.
Any thoughts out there other than manually drawn slabs and p-solids?
