I have a problem surface. Surface has an extend feature that
refuses to remember which edges were picked when configs are
changed. I can manually replace edges and part rebuilds. But fails
again when different config is used.
When I open part extend fails.
An assy with 3 different configs fails. When I fix 1 in the
assy, the other 2 rebuild and fail. It would be comical, if it were
happening to someone else.
This crescent shaped surface was offset in-context from an
imported model in assy. I locked it, then broke it. No change.
