Ghost joint that won't delete

[lkokkone]

Hi all, here I have (again) an isolated file that has a bug. In this file, there is a joint "Rigid64" that won't go away with delete or hide. This joint makes the part impossible to use in an assembly. The joint can only be removed by disabling and then enabling design history. This is clearly a bug and prevents me from continuing my work. I hope that this can be fixed as soon as possible.

There is nothing in this file that can be used in an assembly.

What is the meaning of an orphaned joint?

Exactly. But there is a joint that won't go away.

I'm sorry guenther andresen but you didn't solve the case. Here's a screenshot from the joint on an EMPTY document with everything deleted. WHY do we have a joint in a file that is empty? Please take a better look at the case because this bug is preventing my project to go forward.

yes, this is a bug.  Do you have a way to reproduce it?  What steps did you take that resulted in this orphaned joint?  We would very much like to fix it, but need to be able to reproduce it before we can do that.

I don't know how it came to be. I narrowed the problem down to saved files between versions 51 and 52. The latest version I have is 340, and I became aware of this bug just now. I guess some latest updates made the assembly not accept this orphan joint. Unfortunately, there is nothing I can do to replicate the issue. When I look at the files, version 51 has one joint that is named "Rigid64", and version 52 has two joints where "Rigid85" identifies the same joint on the timeline that was on the previous file "Rigid64." However, if I delete everything on the timeline of V52, the orphan joint gets deleted, unlike the original file I sent. Neverthelöess, I can not delete the orphan joint without deleting everything on the timeline. 

Unfortunately, this design is confidential, so I may not share the original design files with everything in it.

This issue still exists. Is there any news on this.

I've also been fighting this issue. I believe it happens after removing/deleting a component that has a configured joint. In my case, it was specific to the rigid joint on a robot's tool output flange while rigging an end of arm tool for a simulation. When I swapped the EOAT for a revised model, Fusion didn't clean up the rigid joint correctly. These orphans still exist somewhere in the configuration but no longer show up in the component browser. Add-ins like URDF Exporter will discover these orphans and fail -- I added debug statements to the add-in code and confirmed this behavior. No, I won't share my project or code.

My workaround is the same as yours. Delete the parametric history.

Did you configure the rigid joint for suppression?  Can you check if the joint exists in the browser when you switch to other configurations?  I will try to get someone more familiar with joints to help you out with some text commands to detect orphaned joints, if it exists.
