Move a pin inside a cam path

[cubalibre000]

Hi,
how can I mate a pin that can move inside a cam path ?
In NX3 I used the tangent constraints.
I would like to mate to the tangent face or to the sketch that has generated the cut in the plate.
I attach the assembly as example.

Thank you...

Hi,
the solution is :
1) Create a join curve that is the path of the pin
2) Add a distance mate from the centerline (axis) of the pin and the join curve with zero value

Thank you...
