Development main integration (2026-10-12): selected local native SDK proof, 1218 Rust tests and 1066 native checks. Evidence and host requirements.
Open-source jewelry CAD for FreeCAD. Rust owns the logic; FreeCAD provides native geometry and UI.
Development Box clarification (2026-10-12): default two opposite base corners then Height, optional four methods; staged wire preview in four views and Top-view height drag. Rust and native evidence.

The current release targets Windows x64 and official FreeCAD 1.1.4. Using the package requires no FreeCAD source checkout, Rust or Visual Studio.
- Open the FreeCAD 1.1.4 release, download the Windows x64 installer and follow its installation steps.
- Start FreeCAD once. Check Help → About FreeCAD for version 1.1.4.
Its installation folder may be called
FreeCAD 1.1despite the patch version. - Save your projects and close FreeCAD before installing or replacing the OM9 plugin.
Open Release 0.3.5-202610121520, expand Assets and download SetupLauncher:
| File | Download |
|---|---|
| Launcher — recommended | OpenMatrix9-0.3.5-202610121520-SetupLauncher-Windows-x64.zip |
| SHA256 verification | SHA256SUMS.txt |
Source code downloads are for development; install OM9 using the SetupLauncher ZIP above. This release is marked Pre-release.
- Right-click the SetupLauncher ZIP → Extract All. Extract the entire bundle before opening the launcher.
- Keep
OpenMatrix9,launcher-manifest.jsonand allStart-OM9files together in the extracted folder. - Double-click
Start-OM9.cmd. - The launcher installs OM9 in
%APPDATA%\FreeCAD\v1-1\Mod\OpenMatrix9, creates OpenMatrix9 shortcuts on Desktop and in Start Menu, then opens the workbench. - Use the OpenMatrix9 shortcut afterwards. Once installation succeeds, the extracted download folder can be removed; the plugin is installed in AppData.
OM9 uses your user directory; Administrator access is unnecessary for the launcher or FreeCAD. If the launcher reports that the plugin is in use, save and close FreeCAD and retry. It leaves your running application open.
- Use the installed OpenMatrix9 shortcut, or open FreeCAD 1.1.4 and select OpenMatrix9 from the workbench selector.
- Create a document with File → New.
- Select Line, place two points, then try Undo and Redo.
- Check the sidebar, Command area, viewports and Layers panel. Disabled menu entries represent functionality still being developed.
- Save a
.FCStdproject. Finish or cancel a modeling command before changing documents.
To check which plugin was loaded, open View → Panels → Python console and enter:
import OpenMatrix9Gui
print(OpenMatrix9Gui.__file__)For this installation, the path should end in v1-1\Mod\OpenMatrix9\bin\OpenMatrix9Gui.pyd.
- Update: download the next Release's SetupLauncher, extract the complete
bundle, save and close FreeCAD, then run
Start-OM9.cmd. The launcher checks for updates in the background; downloading and installing remain explicit actions. - Previous installations: the launcher keeps them in
%APPDATA%\FreeCAD\v1-1\OM9-backups. To restore one, close FreeCAD, move the current plugin outsideMod, then place the chosen backup inMod\OpenMatrix9keeping the folder namedOpenMatrix9. - Launcher logs:
%APPDATA%\FreeCAD\v1-1\OM9-launcher. - Uninstall: close FreeCAD and move
OpenMatrix9outsideMod. Remove OM9 shortcuts if you no longer intend to use the installed launcher. Your saved.FCStdprojects remain intact.
Download SHA256SUMS.txt from the same Release. In PowerShell in Downloads:
Get-FileHash -LiteralPath '.\OpenMatrix9-0.3.5-202610121520-SetupLauncher-Windows-x64.zip' -Algorithm SHA256
Get-Content -LiteralPath '.\SHA256SUMS.txt'Compare Hash with the line for that exact ZIP in SHA256SUMS.txt.
| Symptom | Check |
|---|---|
| OpenMatrix9 is missing | FreeCAD 1.1.4, v1-1\Mod, InitGui.py, then restart. |
No module named OpenMatrix9Gui |
Rerun Start-OM9.cmd from the fully extracted SetupLauncher bundle. |
DLL load failed |
The Windows x64 package for FreeCAD 1.1.4; read the Report view message. |
| Missing icons or menus | The Resources directory and the complete package contents. |
3DM import worker is missing |
bin\OM9ThreeDmImportWorker.exe; re-extract it from the same ZIP if absent. |
| Launcher does not install | Keep OpenMatrix9, the manifest and Start-OM9 files together; inspect step 5 logs. |
| Update says files are in use | Save and close FreeCAD using OM9, then rerun the launcher. |
Open View → Panels → Report view for errors. Include the FreeCAD version, ZIP filename and panel message when reporting a problem. Match the plugin to its host; do not replace dependencies with DLLs from another FreeCAD version.
For developers: build OM9 against the shared SDK, in Vietnamese.
Gumball 0.3.5: Shift-click or window-select multiple objects to use one shared Gumball in all four views. Move, Scale and Rotate use the selection center; one Undo restores the whole batch. Local validation: 848 Rust tests, 31 native cases / 1,099 checks. Evidence. GitHub Actions builds and packages only.
In progress: Core/History — object lifecycle, rollback and resource budgets.
