Fusion software locking up - no Crash Error Report

TJS01 — Mon, 12 Jan 2026 18:50:19 GMT

Twice last week and now, Fusion locks up. I can't specifically recall last weeks trigger, but today I wanted to delete an extrude feature (via the timeline). The part is a simple flat plate with holes. I do have a larger assembly open and a few other simple parts open if that matters.

It would appear at this point, like last week, the only option is to End Task in Windows Task Manager.

Running Fusion 2605.1.52 on Win 11 Pro 24H2 (26100.7462)

Hi @TJS01 ,

Thanks for reporting this.

To help us investigate this further, could you please provide a bit more information?

If possible, please share the dataset where this occurs (the part and, if relevant, the assembly).
You can export the files as .f3d or .f3z and attach them here. Having the actual data will allow us to try the same operation on our side and see whether we can reproduce the hang.
If you’re able to capture it, a short screen recording showing the steps leading up to Fusion locking up (for example, deleting the extrude feature from the timeline) would also be very helpful.

Additionally, please let us know:

Whether this happens consistently with the same file or intermittently across different designs
Approximately how long Fusion is unresponsive before you end the task

With the dataset and (if possible) a video, we’ll be in a much better position to determine whether this is a file-specific issue or something more general that needs to be escalated.

Thanks for your patience, and we’ll dig into this as soon as we have more details.

Not necessarily resolved, but after posting the issue, I did not have a problem for the rest of the week and I had been working in the same dataset the entire time.

@TJS01

Did you pattern circles in a sketch?

Or did you pattern one single hole feature?

Holes are not patterned.
