Terrain hole fixed the problem. I'l probably never know the root cause of the problem. Thank you very much for your help!

I have a lot of work in both the terrain and the basement. I don't know how to create a terrain hole. I also don't know what changed. I've compared a previous version contour by countour, wall by wall, and don't see what changed to make it go insane.

Here's a picture of what it's doing inside the basement crawlspace. Hide terrain intersected by building was already checked. Changing it doesn't have any effect.

Thanks! Hide terrain intersected by building helped a little (it cleared up some odd artifacts down the side of the building). But the slope still shows in the basement. I can't go back to a previous version because I made a ton of changes before noticing this problem.

I had a basement modeled correctly, then made changes unrelated to the basement (and didn't modify the slope lines), and the next time I generated 3D, the slope showed up in the basement! I've compared all of the settings for the slab, pony wall, outer walls, etc. and they match. The slope lines are also the same. Any idea how to fix this?
