PartDesign: Pocket through revolve creates a "skin" of the pocket on one side

[gitnoel]

Is there an existing issue for this?

Problem description

When pocketing a circle through a revolve it produces an 'extruded skin' on one side of the pocket. I tried with a second body, creating pad of a circle, and pocketing another sketch through it and it worked okay.

This could be an OCC bug and is also present in the stable 0.21.2 version. Could you create a topic on the forums, I'm sure this is a known issue.

[gitnoel]

Sure I'll create a topic. This is the first time I've struck this particular issue, maybe I've been fortunate?. I don't know what an OCC bug is, sorry.

Issue is still present in 1.02.
A workaround has been to offset the circle center by 0.001mm vertically
