Hi.

I have a problem.

Say I want to use a Tangent Mate to allow movement between  follower and a face (like cam and follower mechanical mate but without the need for a closed loop).

Now, lets say that the face I want to be tangent to, in made out of 3 different faces ( two flat faces and an arch between them ). I used delete face and fill to remove the edges between the surfaces so I have one smooth face.

In the assembly, when I try to choose that face for the tangent mate, it wont select it...

I also tried to create a surface from the face and use it for the tangent mate but Nope.

any suggestions on how to achieve this?

regards

Ben.
