How to make a joint connection that follows a specific path?

I have this link that needs to follow a semi-circular axis.

See attached screenshots. I have an axis there but I can't choose it.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

sure, here you go

This won't work in the real world.

A straight Ø10mm cylinder will not slide through a Ø10mm hole (at least not without a press to force overcoming friction).

Given that logic:

A Ø10mm cross-section torus will not fit through a straight Ø10mm hole.

I recommend that you redesign your components (and also, fully define your sketch in the torus geometry.

Attach the new file(s) here.

(And for reference - I would create both of these Components within a single file rather than as separate files.)

Wait, what? That's just an example for practicing joint things in Fusion 360. Let's just forget about real life and pretend that this is a 100% friction-less thing like you see in the texbook problems. How would you make this simple path-following dot relation thing in fusion 360?

I'll move on to real work.

I can't believe this 😂 Okay move on than. It's weird way to say "SORRY, I DON'T KNOW EITHER" 😂

pin slot only supports a linear path.  since your path is an arc, you can fake what your trying to do by adding a dummy component with a revolute joint. see attached model.

I know my model is not yours but I wanted to send it to you to show you can combine some Joints and Features together to get motions that are not normally available in Fusion 360.  Maybe it will give you some ideas.  You animate it using the Drive Me Joint.  Model attached.

Same problem here....similar would be more acurate. How do i make a joint trought the path in red. Is it possible to do it in fusion?

This is a different situation where you have to create a planar joint and a tangential relationship.

Many thanks! Worked like clockwork.

Still with problems if we have this type of situation, when it gets to the end of the rail it drops off. I send to you the project fusion file. How do i manage this type of situation?
