Line to face sliding mate

Just_Julian

Hey everyone! I've been trying to figure out how to make a line mated to a face in an assembly so when the face/plane changes it's angle around a ring, the line connected to the face moves along with it, but staying flat.
I have a ring with multiple arms coming off of it that can rotate down, and now I need all the arms to move in sync, so when I move one arm a few degrees or a lot, all of them move so the top of the arms are all parallel. I've tried multiple things such as the slider mate and such, but can't seem to find anything that works. Everything seems to only want to work with faces/certain parts of faces, but never the line itself. I'm used to SolidWorks, but I've recently gotten into Onshape and I've done a few things already

Thanks for any help!

Can you post a link to your document or a screen shot, so we can better see what you are trying to do?

Fastened mate should be your first choice, it should remain perpendicular to the face as it moves.
