Following a curved path in an assembly
outstanding
Member Posts: 56 ✭✭
If I want the vehicle to follow the curved rail (blue), what kind of joints can I use?
I have tried using my imagination but cannot see, how this can be made to move in Onshape.
In other tools, I can imagine creating a mate between the wheels that then "slides" along the curved path. I will likely make a revolute joint since the curved section is a circular arc. How would you approach this?

Should probably be feasible with a couple of tangent mates. Thanks
This is the first time I'm using a tangent mate. Did read the documentation, but here it's clearly not doing what I would expect.
Expected:
- wheel surface follows the curved rail
Actual:
- there is some constraint, but the selected faces don't touch

1. If I choose a face for the Tangent Mate, it acts weird
2. If I instead choose an edge, things remain more tidy
What I did to create such a mid-edge is make a slight draft to the extrusion of that wheel. This will likely get me further with my model, but clearly work could be done to improve the Tangent Mate.
