Fusion 360 Project Downloader

Export entire Fusion 360 projects in bulk with a friendly options dialog. Choose output formats (F3D, STEP, STL, IGES), include sketch DXFs, export current and previous versions, and optionally preserve your Hub/Project/Folder structure on disk. Progress, cancellation, and a per‑run log are included.

Installation

You only need the Downloader folder (it contains the manifest and script files). You can either add it directly in Fusion or copy it to your user scripts folder.

Option A — Add from Fusion UI

• Open Fusion 360 > Utilities tab > Add‑ins > Scripts and Add‑Ins…
• In the Scripts tab, click Add…
• Select the Downloader folder (the one containing Downloader/Downloader.manifest).
• The script appears in “My Scripts”.

Option B — Copy into user scripts folder

• Windows: copy the Downloader folder to %APPDATA%/Autodesk/Autodesk Fusion 360/API/Scripts
• macOS: copy to ~/Library/Application Support/Autodesk/Autodesk Fusion 360/API/Scripts
• Restart or refresh the Scripts and Add‑Ins dialog.

---

Usage

1. Open Fusion 360 and ensure the Data Panel is open with a project selected (the script exports the active project).

2. Utilities > Add‑ins > Scripts and Add‑Ins… > My Scripts > select “Downloader” > Run.

3. Options dialog: choose what to export.

• Output folder: pick a location to save files.
• Export formats: IGES, STEP, STL, F3D (checkboxes).
• Versions: current only, previous N, or all previous.
• Sketch DXF: include sketches as .dxf files (optional).
• Preserve structure: keep Hub/Project/Folder hierarchy on disk.

4. Confirm plan. A summary pops up; click OK to start.

5. Progress dialog shows the current action and allows cancel.

6. When complete, a message shows saved/skipped/failed counts. Open the chosen folder to see results. A log file is written to export.log in the output folder.

Output Structure

• If “Preserve structure” is on: Hub/Project/Folder/.../Files
• If off: everything is saved directly under the chosen output folder.
• Filenames for design versions include the version number, e.g. Part Name v7.step.
• Non‑design files (e.g., PDFs) are downloaded in their native extension.

---

Troubleshooting

• No options UI appears:
  • Make sure you added the Downloader folder that contains Downloader.manifest.
  • Click refresh in the Scripts and Add‑Ins dialog; remove duplicate copies.
  • Ensure a project is active in the Data Panel.
• See errors and logs:
  • View > User Interface > Text Commands to see console output.
  • Error popups include Python tracebacks.
  • Check the run log at <your output folder>/export.log.
• Permission errors when writing:
  • Choose an output folder where you have write access.
  • Close files that may be locked by other apps.
• Cancel doesn’t stop immediately:
  • The exporter checks for cancellation between units of work; it may take a moment to stop.
