I'm trying to constrain the motion of a cylinder inside another cylinder. I have a point in one part and a curve in the center of the 2nd part. I can create a constraint using the point and curve (using coincident or path) but there are no limits. I can drag the first part "off" the other part. Shouldn't the part stop when the point reaches the end of the curve?

I found a similar example in another post and it works properly. I can't figure out why mine is unconstrained. See the image below where the point has separated from the curve.

Thanks,

Matt

Use a spline (two points, no curvature) instead of a line segment.
