I was wondering how everyone does their exterior finishes in 3D? I understand that you have to create new walls to get half stone and half siding and so on but how do you get the stone to cover the foundation. In the picture I shared I just raised the site plan up but still have exposed foundation on the side. Or another example would be the other picture below. If you have a 1 foot foundation above grade and want to extend the stone down over what's the easiest way to do this for the 3D model?
