Steady Rest (Siemens NX)

[Siyabend42]

Hello Friends, I am designing a "steady rest". I have a problem with the "self-centering" mechanism. I could not extract the natural path curve required for the pusher pulley. This path is not a 3-point arc, it is a spline, I could not find a solution. Is there an easier way to extract this curve? I couldn't find a path extraction option in NX Motion. I am trying to extract an intersection curve/surface between the bearing and the arm.
