Fusion - Drawing Red box issue, windows 10, 11/11/2025

[Montypersonal77]

Hello,

I am facing a critical, project-stopping bug that has appeared within the last few days, following the most recent Fusion 360 updates (one today, and one a few days ago).

The Core Problem: Every single view, across all sheets in my drawing files, is losing its reference and turning into a red box. This happens immediately after I make any change to the source 3D model and the drawing relinks to the new version.

This is not an issue of one or two broken links; it is a total and catastrophic failure of the link between the design and the drawing.

Key Complications & Details:

1. Triggered by Any Change: This isn't caused by a major geometry change. I've confirmed that simply adding a new "Named View" to the design file (a change that affects no existing geometry or drawing references) and saving it is enough to trigger this bug. When the drawing updates to this new version, every view breaks.

2. System: Windows 10: I am running Windows 10. When I attempt to use the in-app Autodesk Assistant to get help or contact support, it informs me that technical support is no longer provided for Windows 10 and stops me from proceeding. This leaves me completely unable to submit a formal bug report or get direct help.

3. "Promote Version" Fails: Based on a suggestion, I tried to roll back my design file to a previously known-good version (e.g., Version 31, which I knew worked perfectly). I right-clicked v31 in the data panel and used "Save as Latest." Even after promoting this stable, older version to be the new "latest" (Version 33), the drawing still broke and showed all red boxes upon relinking. This seems to prove the issue is not with my design file, but with the linking mechanism itself.

4. "Edit View" Fails: Once a view becomes a red box, I cannot fix it. Clicking "Edit View" and changing the orientation (e.g., from Northeast Isometric to Southeast Isometric) and closing the dialog does nothing. The red box remains.

Troubleshooting Already Attempted (No Success):

• Restarting Fusion 360

• Restarting the computer

• Clearing the cache (deleted multiple times)

• Manually trying to "jiggle" the view settings via "Edit View"

• Promoting a known-good older version of the design file using "Save as Latest"

Summary: As of the latest updates, my drawings are unusable. I have many sheets and views, and manually re-creating them is not an option, especially if any subsequent design change will just break them all again. I am completely blocked from producing updated drawings for my designs.

My Questions for the Community:

1. Is anyone else experiencing this specific "red box" behavior after the latest updates, particularly on Windows 10?

2. Is this a known bug that the development team is aware of?

3. Is there any workaround (other than upgrading to Windows 11, which is not an immediate option) to re-establish the drawing references?

Thank you for any help you can provide. This has brought all production work to a halt.

Hi @Montypersonal77 ,

Could you please share the Fusion version number you're currently using?

Also, does the red box issue occur when creating a drawing with a template, or does it happen even when you create a drawing without using any template?

If it appears to be related to a template, please review the article below and check whether the suggested solution helps.

Hello @Montypersonal77 ,

This looks like a known issue(FUS-225114)with drawings created with template.
Since you are on the Windows 10 machine, I want to just double check if it is the same issue.
can you please send me the sample model and template you have used to create the drawing?

As a workaround, can you please right click on the browser tree in drawings side and click on unsuppress All components?

1. After updating the design, save the design
2. Now go to drawing and get latest
3. Notice we see different sheets show red boxes(supressed)
4. For sub assemblies which are shown as suppressed, just right click from browser tree in drawing and click on unsuppress All components

Note: Care must be taken when unsuppress as if it was already suppressed before making get latest those components may also be unsuppressed.

Experiencing the same issue on Windows 11 and came to check if this was already known. Thank you for providing this workaround as it at least saves redoing the drawing. Hopefully the issue is resolved soon.
