Toposolid: Excavate and Remove Excavation

Use a floor, roof, or toposolid to cut volume from a host toposolid.

Floor, roof, and toposolid elements which intersect toposolids are used to excavate volume from the host toposolid. For example, you can place a floor element in a sloping toposolid, use the excavate tool and remove the volume of the toposolid to the top of the intersecting floor, or use two overlapping toposolid elements and use one to excavate a parking lot.
