Please take a look at the attached image.
I made a cutout of a tube using a thickened surface wrapped around a curved surface. Likewise I made an insert.
The fit niceley, I can mate the outer surfaces and move the insert using Physical Dynamics.
Now I want to mate it in such a way that the insert slides into the cutout without intersecting the tube. (When I drag without physical dynamics).
I can't select the edges of the cutout or insert while creating a mate. And I also can't seem to mate the surfaces where the insert touches the cutout.
A screw mate might be able to do that.
