Guru's, Is there a way to create a cam follower that is defined from TWO SURFACES? I have some kinematic analysis to do on EXISTING parts/models. I have a slide part with a roller following a cam. The cam is a three dimensional surface and the follower's slide axis is not coplanar to the axis of the cam. It's odd motion... The designer used a driver on the cam to produce a trace curve on the cam and then used that to create the cam surface. Unfortunately, he defined the cam surface on an orthogonal plane which isn't correct. What I would LIKE to do is set up a cam follower with the actual roller surface "finding" it's tangent contact point with cam profile surface. Then I can analyze the resulting motion to see how far off from the "perfect" motion it is... Thanks... Paul Korenkiewicz FEV, Inc. 4554 Glenmeade Auburn Hills, MI., 48326

I've done this - once. You define all of your mechanism constraints in standard assy mode, except the cam. Then you need to go into mechanism mode to define the cam. As I recall it wasn't that hard, once you got through the typical Pro/E eccentricities. I think once in mechanism, a sub tree appears or maybe new branches in the standard tree. There's a 'cams' branch and I think you maybe RMB on the branch to define a new cam? I'm afraid I don't remember all the details, hopefully that'll get you pointed in the right direction.
