How to create a CAM profile using relations in pro-Engineer/Creo-parametric?

Here's the answer...
p.s.In the step-14 I 'd have changed the dimension to 50mm...so please implement it in the 6-th step also...instead of 40mm ,change it to 50mm

Note:It's a creo parametric file. :)

tracing point in mechanism when all other motions are defined except for the shape of the cam,is right way to make cam

after defining motion of cam shaft,follower,rocker arm,valve,cam profile can be traced easily.
