Swapping Structural Foundation Slabs with Iso Footings

@Alisder_Brown the bounding box idea is good. But when the element are at an offset, the point shows the Z elevation but family instance places it at level zero. it’s weird but that’s what happening.

Also is there a way to select the family type by name. the idea is the name of the foundation slab matches a generic structural foundation but with type properties, which means we will create types already and when the name matches the family type it places that respective family. is it possible.
