I have been making a plan my house so I can use this program to do upgrades and renovations. There is a concrete slab outside a basement door, then a concrete ramp that goes up to ground level. I did the terrain before I made the slab and ramp, and I cannot seem to get the terrain to get out of the way (see attached images). I know I still have to adjust the height of the far end of the ramp, and that is easy. The top image is the first floor orthographic view, and the bottom image is the basement orthographic view. If anyone has any suggestions, I would be most appreciative.
