cylindrical and parallel mate conflict
Hey Guys,
I have encountered a problem, where I have the inner part of the bearing connected to a rod via cylindrical mate and the outer part of the bearing, to be more specific the plane area with the bore holes, must be parallel to the marked side of the servomotor, no planar mate. In theory this connection must work, but for some reason it fails here.
The blue arrows indicate the parallel mate and the red arrows the cylindrical mate. The inner part of the bearing is rotationally independent from the outer part of the bearing. The bores of the linkage rod only have cylindrical mates.
Additionally, I was able to create the aforementioned cylindrical and parallel mate, but the linkage rod was suddenly constrained to a horizontal position. I want the linkage rod only constrained with the two cylindrical mates and nothing else, so actually it should move freely in a 2D-plane.

You could try adding a "dummy part" (like a sketch or surface) between the bearing and rod, with a ball mate between it and the bearing and add the cylindrical mate to that. It's a workaround but it could help, you could then use the measure tool to see if you have some angle between the bearing and rod axes and if so work backwards to find the issue.

It looks like you might have a long "chain" of mates involved, math rounding errors could be causing the issue but it's hard to tell exactly without seeing the document, are you able to share a link?
