Hello. I'm working on a drawing with a walk out basement, but the walk-out comes out onto a patio that is sunken and then there's a step up to go out of the patio to ground level. I've created terrain perimeter, and retaining walls, and a slab, but I'm having issue with the terrain still continuing into the sunken patio area. Any suggestions on how to make this work in the 3D view? I have deleted and redrawn the retaining walls multiple times and rebuild terrain and it always come out this way.
