Fusion 360 API Trouble Generating Flat Patterns for Sheet Metal Bodies

adminREEL6 — Fri, 25 Jul 2025 09:54:06 GMT

Hello everyone,

I’ve designed an assembly that includes a component made up of multiple sheet metal bodies. I’d like to export a DXF flat pattern for each body.

I quickly realized that Fusion 360 only allows one flat pattern per component, so I wrote a script to create a separate component for each body. That part works fine.

However, I’m stuck on generating the flat patterns automatically. My script fails to detect the sheet metal features, even though all the bodies appear correctly as sheet metal in the Fusion browser.

Has anyone successfully scripted this process, or could point me in the right direction?

Thanks a lot in advance !

Elie
