Fusion 360 Local Save Extension This Fusion 360 extension brings back easy local saving by letting you export .f3d files directly to your computer, bypassing the cloud-only model almost completely. Conversion and native export are still needed for f3z archives.

Saves the current document as a local .f3d file

Ideal for backups, version control, and offline work

How to Use

C:\Users\<YourName>\AppData\Roaming\Autodesk\Autodesk Fusion 360\API\AddIns\ (Windows)

Open Fusion 360 → Tools → Scripts and Add-Ins

Find the extension under the My Add-Ins tab and click Run

Use the new "Local Save" tab in the toolbar to export files
