Driving an Assembly Constraint Offset with a Joint Parameter

Hello,

 

My product is Inventor Professional 2014.  I am working on an assembly in which a horizontal shaft is supporting a chain which hangs down on either side.  On each end of the chain is an object.  As chains are quite difficult to animate in Inventor, I have tried to work around that by applying a cylindrical joint with limits to one of the objects (a round plate which is to move up and down within a cylinder) and then applying a flush constraint to the object on the other end of the "chain" with an offset driven by the current position parameter of the round plate.  The idea is that as I move the plate up and down in the cylinder, the other object will change position accordingly.  The plate moves up and down in the cylinder as it should, however, the other object remains stationary.  Any advice on how I can fix this problem?

 

I am unable to share pictures of the actual assembly so I drew a quick diagram to illustrate the motion I'm trying to simulate.

Hi @jlasser.

To simulate the chain i use pattern function and adaptive sketch. (See video bellow)
