_projectToCPlane
has a bug. (as far as i can judge)
attached document has a free cplane.
projecting the blue edge of a revolve (subselect) I get the red curve.
I would expect the green curve
workaround via _setPt
@Gijs thanks for a test - bug report
or explain what I misunderstood - due to the temperature ?
I see this error in the same-dated Windows version too, provided you project the sub-selected black surface edge. If you project the blue curve the result is correct.
@pascal: might you have projected the blue curve instead of the sub-selected surface edge?
@pascal What I don’t get from your images is that the surface is moving away from the blue curve, that’s why I thought you were projecting the surface.
Or wait… DeleteInput = yes does that. Try = no
