Glancing over the fact that the vertices don't snap to eachother, so I'm forced to snap them to the corners of a box. But this simple 4 sided patch fails to build. Maybe I'm using it wrong?
I looked at it and I can reproduce the problem, using just linear sketch edges. It seems as if one tries to use more than one sketch edge then the conversion will fail. I was able to make a patch using two edges from the box and one sketch edge, though. I think it's a bug.
Yeah, its a bug (in parametric case). It works perfectly in direct modeling environment. We have already resolved this issue and the fix will be available in the next release.
