Assembly Constraints in Pro/E

[goomba]

I have a door that will open/close vertically. Cam followers will guide the door inside grooves in the door frame. On the door frame, I drew a sketch then a curve along the groove. (the groove in the door frame is vertical then curves inward at the bottom) In my assembly, I'm trying to constrain the door asy by using a point to curve - there is a point on the cam follower. The door will be lifted by pneumatic cylinders on each side. The idea here is to change the position of the cylinder rod and the door will follow but remain constrained along the curve. The problem I'm having is that when I use the "point-to-curve" as an assembly constraint, it only allows me to select a portion of the curve - it doesn't treat the curve as a single item but 3 pieces - the vertical, the radius at the bend, and the slanted part. Any ideas? Thanks!

Send me some Snapshot of your Issue, if you could?

I have attached a view of the groove in the door frame and the cam follower in the groove. I would like to constrain the cam follower to the groove so that when I change the height of the pneumatic cylinder shaft the door follows.

I think you can create a composite curve which is one curve defined by the three. You can try using that new curve as for your constraints.
