Joint Origin and Imported Components [BUG?]

Beyondforce — Thu, 08 Sep 2016 07:03:23 GMT

Hey Guys,

I have imported a component and I want to create a Joint Origin on it. Now, I have two option, either Break the Link or Create a sketch on one of the components faces and then I'll be able to attach the Joint Origin to that sketch.

But, when I try to joint the component, I can't use the Joint Origin as Component1, only as component2.

If I break the link, then everything is fine.

Please watch the screencast:

Cheers / Ben

If you right click on the XREF'd (linked component) and select Open. Could you add the Joint origin in that design and save it?

After doing this, when you go back to the assembly, can you create the desired joint?

In the model browser, it looks like a joint origin is being added to the root component and not the inserted, XREF'd component. I suspect this is the reason you are having difficulty with this joint.

Please let me know if you have any questions. I am happy to help!

Thanks,

Hi @innovatenate,

It worked the way you suggested. But it still sounds like a bug and not a limitation! It doesn't explane, why I can choose it as component2 and not component1?

I think the confusion here is regarding where the joint origin "lives."

In the first attempt, the joint origin lives in the root component, the top-level of the design. This joint origin is associated with the root component's origin. In this case, the joint origin is not associated with the component Pin v1:1.

In the second attempt, you insert a new joint origin but I do not see it listed under the root component. The model browser is not expanded, but I would assume that the joint origin "lives" in component Pin v1:1. Is that correct? If so, then this joint origin is associated with component Pin v1:1 and should explain the difference in behavior.

Does that help? Let me know if I'm overlooking something. I'm happy to help.

Thanks,

Thanks for the reply.

Hopefully the below screencast will help explain this a bit better. Let me know either way! I am happy to help!

A distinct Joint Origin, not the ad-hoc joint origins created by a "normal" joint has to live within a component.

Linked components cannot be edited in place a the moment. they are static in the design they have been inserted to.

Thus Fusion 360 does not allow you to add a joint origin to that linked component,.

You have to open that linked component separate and ad the joint origin, save the linked component/assembly and update the design it's been inserted to.

Then you have access to that joint origin.

Distinct Joint origins are also the only objects in a linked component that you can hide/show in a linked component.

Hi @innovatenate,

Thank you for the screencast and the explanation, a very good explanation indeed. As I suspected, this is just a limitation the same as the editing an imported component inside the assembly.

@TrippyLighting, thank you for pitching in.

Ben.
