Why not make all cutouts the same depth relative to some arbitrary horizontal surface, say the max landscape height? I can see that might make the building models slightly more complex in that each will need a spacer under them equal to the height delta at that location (assuming they are created seperately and slotted into the landscape later).
Thats exactly what i was trying to explain yes.
I've taken that approach before and was working out to be taking too long. The solution we're looking for is to cut down on time significantly. If only the company that does it for us would tell us the name of the software it could be solved! But obviously then we'd stop sending them work so they're keeping it to themselves!
