SHEET METAL error - Fusion

xbodis — Thu, 20 Nov 2025 16:51:37 GMT

Hello everyone,

I’m having a problem with the Sheet Metal Flange feature, specifically with the Two Offsets option. I didn’t have this issue before the latest update, but after updating I’m getting this error every time.

I enter all my inputs correctly, select OK, and the flange is created. However, when I try to edit the flange again, Fusion shows an error. Edge 2 and Edge 4 always lose their offset values after reopening the feature. I have to reselect the full edge, re-enter both offset values, and confirm again. When I reopen the flange, the same error appears.

Please help.

Thanks!

Share your Fusion file?

Hi! Either the neighboring Flanges are colliding or the Bend Relief or the Corner Relief setting is incompatible with the Flanges. Try changing the width option to narrow the Flange width, allowing more room for neighboring Flanges.

Please feel free to share the f3d file here or send it to me directly at johnson.shiue@autodesk.com. I would like to understand the failure better.

Many thanks!

Hi, I'm facing same issue,

Fusion allows you to create a "Two Offset" flange with two or more edges but when you try to edit it, it shows the error message as shown in the screenshot.
What I noticed is when only one edge is selected this issue does not occur, add a second edge and the issue occurs.

Pic_1 Show the edges that are selected.
Pic_2 show the error message and the flanges are missing.

Tried with the built-in sheet metal rules - the issue persists.

The "Two sides" flange option does not have this issue.

Fusion version: 2605.1.39 x86_64

Hi! I just tried the workflow on the latest internal Fusion build (targeting the coming major update). The issue is indeed fixed there. I believe it will be fixed on the coming update.

Many thanks!
