Catch to construction geo intersection not working
I'm having a terrible time trying to catch to construction geometry. No 3D parts involved yet; I'm laying out the initial profile on WP1. I'm trying to overdraw a horizontal construction line to its intersection with a construction circle, and Catch doesn't seem to recognize the intersection, even when I limit Catch to Intersection. It insists that a point a few thousandths of an inch beyond the intersection is the right place to catch to. Everything else seems to work nicely. What am I missing? Any ideas?
