I am making a PLTW Train in Onshape and need help running it around the track. Here is a link. https://cad.onshape.com/documents/c1426e6a74739e5b840fefd2/w/9a6a503e33f9812ef61f2123/e/1c575ea47a3320ad676b4b75

The link you provided no longer works. Do you still need help with this?

It also wont properly animate with this dimension.

Sorry for the late response. The project is probably solved or finished by now, but here is what I would do:

When I animate parts along a path, I usually try to constrain the part to a single surface with no breaks (An example is posted here). This makes it easier, but may not have the distance per revolution you are looking for.
