I am wondering how everyone is modeling irregular shaped footings in Revit Structure. I have a project with many deeper under-floor footings for machinery. These footings are shaped irregularly in plan, and have cutouts with varying height, slope, etc. in their slabs for placement of the machinery. I have done a couple with in-place families, but is there a way to do this with slabs? I'm not sure how far the slab edge tool will go in this. Just wondering how everyone else is approaching this - I searched here but didn't find answers for this specifically. Thanks.
