Bye, guys. I used the search function in the forum but I found nothing to do with my case. are struggling with creating a banal seat for a hole stop ring, but I just can't. I have little experience with catia and at the course they taught us to do only external seats (e.g. piston bands) with tongue command starting from a sketch. Now I find myself in trouble, because I can't create a sketch on curved surface when around I have material, I don't know if I explain. how do you in general create your homes? I attach image that maybe you can clarify a bit. the problem can be reduced to the case of a parallelepiped with a hole in the center, within which to develop the quarry. thank you for the help and apologize for the perhaps trivial question.
