BumpMesh for Fusion

Send a copy of an editable Autodesk Fusion solid body into BumpMesh, choose the faces to texture there, and save the finished STL or 3MF. The source Fusion body and its timeline are never modified.

Workflow

1. Select one solid body in Fusion.
2. Run BumpMesh from the BUMPMESH panel.
3. BumpMesh opens in include-only mode with no surfaces selected, so texture is applied nowhere until you choose faces inside BumpMesh.
4. Choose Export STL or Export 3MF.
5. Choose the destination in Fusion's native save dialog.

The BumpMesh palette overlays the right side of Fusion and scales to 55% of the current modeling viewport, so it adapts to different screen sizes on both macOS and Windows.

Updates

Choose Check for Updates from the BUMPMESH menu. A newer compatible release offers a download link; installation is always your choice. Automatic checks run quietly about once a week while Fusion is running. You can disable them in the same dialog and press Done to save the setting. An available update is indicated in the menu, without interrupting your work.

BumpMesh loads some dependencies from the internet, so an internet connection is required when those dependencies are not already cached.

Install

Quit Fusion, download the installer for your computer, and run it. Reopen Fusion and the BumpMesh button will appear in the BUMPMESH panel.

• Download for macOS
• Download for Windows
• Manual installation ZIP

Manual installation

Download the manual installation ZIP and copy the complete BumpMeshForFusion folder into the appropriate directory:

• macOS: ~/Library/Application Support/Autodesk/FusionAddins/
• Windows: %APPDATA%\Autodesk\FusionAddins\

Restart Fusion after installing or updating the add-in.

Development

Run the integration tests with python3 -B -m unittest discover -s tests -v and node --test tests/test_fusion_bridge.cjs (Node 22 or newer). Installer sources are under packaging/; the GitHub Actions workflow builds the macOS package, Windows installer, and manual installation archive from the same commit. CI packages are build artifacts, not signed release approval. Public macOS releases use packaging/macos/build-release-pkg.sh for signing, notarization, stapling, and Gatekeeper verification. Installer versions must match the manifest.

Uninstall

• macOS: run Uninstall BumpMesh for Fusion.command inside the installed BumpMeshForFusion folder, or remove that folder directly.
• Windows: open Installed apps, select BumpMesh for Fusion, and choose Uninstall.

Support future tools

BumpMesh for Fusion is free and open source. If it helps in your shop, you can optionally support future Extrusion Therapy tools. The installers and source remain available without payment.
