Thanks Michael
I need project command for various ring shank shapes.
The project command is a must for me at the moment so I will have to go to MOI 1 or Rhino for it.
Yes, thanks I understand about tolerance.
But please notice that the photos above close-up photos – they are not close-up yet snap catches two intersections.
And as I said above MOI 1 does produce only one intersection there.

Thanks
Olga
