I think there are two problems with the prescribed method in the video.
One; it may be parametric, but not dynamic. You cannot move the points (the master reference) about the curve because the patterns fail once the start is other than leader value along the curve is anything other than 0.
Two; the points are located at arc lengths along the curve. Chain links move at cord length offsets along the curve. This introduces a level of error that is not tolerated by constraining both ends of the chain. in the tutorial, the links merely follow the CSYS orientation.
I also ran into some kind of pattern bug that didn't allow me to create the second set of CSYS references. It always reverted back to the original point instead of the following one. I know that Creo 2.0 M040 still has some serious pattern bugs so this may be fixed by now. I will consider reporting it anyway since I can now repeat the issue.
I know I can drive a chain along a track through an assembly using a servo motor.
Have a look at this discussion and included video:
I have to ask what your end game is on this effort. And how many links are you proposing?
