I'm trying to create a revolved boss, but fail to do so even if the preview works just fine. Here's a simple reproducible example: A circle, and a centerline which have a tangent relation so the circle should rotate just fine around the axis. Even so, I get a rebuild error stating that the sketch is open (just a circle), self-intersecting, or intersecting the centerline.
Can this be done? Does it create some sort of a singularity point at the axis, or what goes wrong?
