Draft angle analysis issues


I want to make a 2-part mold and I need the parting line.
The curve that gets generated trough draft angle analysis have some sections that are not “touching” the object. So my question is why is this happening?

Hei Andreas -

It looks like the DraftAngleAnalysis command has issues with certain SubD objects.
I’ve put this on our list as item RH-69105 so that a developer can take a closer look.
