How do you simulate a 1 way bearing?

I'm trying to simulate a 1 way bearing (sprag clutch) in an assembly for a ratcheting cvt, any idea on how to make a 1 way rotating mate?

Just for animation purposes, it is possible to create a sprag gear (non-continuous contact) by including a hidden component that describes the path of the sprags (mating to a sketch for best performance).

Hi Caleb, welcome to Onshape!

Do you actually need to see the sprags move / contact or do you just want one-way rotation? Neither is really possible since Onshape does not support contact or one-way revolve mates. Does it need to be shown only rotating one way?

Still no way to simulate a one way bearing somehow?

I asked the same maybe half a year ago and was told there isn't. I ended up animating the full reciprocating motion, and then cutting out all reverse movements from the video, so only movement step-by-step in one direction was visible at all times. Still, I think it would help in simulation when there were one-way-bearing constraints in Onshape.
