Chase wall for plumbing

I'm glad you were able to get it to work. By the way, those temporary points are handy to use when manually editing roof planes. There is a technique to get them to automatically appear at points of intersection of roof plane edges so that you can better fit two (or more) roof planes together at a common point. I'll leave the discussion of that technique for later, but I wanted to point out that those points might seem to be appearing at random if you're not aware of how they work, and the next question is about how to get rid of them ... which is done the same way as described above.

Good luck.
