Joint missing reference after breaking link

Harold_Weistra — Wed, 26 Mar 2025 08:09:30 GMT

Hello all,

Since two updates, I have experienced something strange in assembly joints.

I created a model with linked components that I joined into place.

After breaking the links, fusion now reports missing reference geometry and displays a warning. The joint however still function as designed and intended.

What is causing this behavior? I don't understand what's wrong.

Hi @Harold_Weistra , Was the break link done on Derived components or External Reference components?

Hi Mayank,

It were External components, no derives.

Thank you @Harold_Weistra , For derived components break links looses the reference, but for external components, this should not have happened. To investigate this further, can you please attach any of the assemblies (Voetstuk v1 or Haak v1) you inserted in this main assembly file https://a360.co/3Y6Kpm7 you have attached above. We will have to check what is going wrong at the time of insert or break link at our end.

Sure, no problem! Thank you for looking in to this.

Working assembly attached.

Thank you for sharing the files, it will be helpful for further investigations.

In the meantime, the joint feature warnings can be resolved by editing the joint and reselecting the geometries.

Any chance for a solution Mayank? I have more assemblies that have the same issue.

Yours,

Harold

@mayank.malukani I found this very easy to reproduce on this super simple assembly. I would expect that this has the highest priority and is fixed very soon, perhaps even with a hot-fix!

@TrippyLighting We will certainly raise the priority for this.

Wanted some information that might help in our investigation : I was able to reproduce this in the file provided by @Harold_Weistra , but not on a fresh assembly I created. Were you able to reproduce this in a design you created from scratch? If yes can you please share your design/steps?

I am trying to figure out if this issue is happening with some specific models or is generic.

I downloaded the two components the OP posted and uploaded them to the data panel. I then inserted them into a new Fusion design and assembled them.

Then I broke the link of part 2 and the joint turned yellow.

Hello Mayank,

I created a new project and new parts and assembly. Indeed, the behavior did not happen now.

When I create a new assembly with the parts I sent you and break links, the error still appears.

It seems it only happens with older external component files, created over a year ago.

In addition:

I unarchived a 4-year-old project containing similar files. Breaking a link did not create a conflict.

Does that help?

Yours,

Harold

Thank you for trying and confirmation @TrippyLighting!

That was my observation too @Harold_Weistra . Thank you for confirming, it is helpful. Looks like the part files you sent had some specific issues , we can limit our investigation to those files only.

Hi Mayank,

my previous addition were 4 year old files.

Just also unarchived a 2023 project and that does show the same errors.

Is it helpfull when I share different files from different years? Can I add you to a project as a member in that case?

Yours,

Harold

@Harold_Weistra Thank you for sharing this. I would say, we can wait for the initial investigation to complete and I will let you know if we need access to the old files .

Hello Mayank,

Unfortunately, this problem continues to occur in the latest update. Does this still have your attention?

An update would be appreciated.

Cheers,

Harold

Installed update Fusion 2601.1.37 x86_64 today. The problem seems to be resolved.
