Open CAD Studio is a cross-platform application for technical drawing, layout work, and solid modeling. It reads and writes DWG and DXF drawings natively, with a shared editing core across the desktop and browser versions.
The project is under active development. Keep backups of important production drawings and report reproducible problems through GitHub Issues.
wgpu, with orthographic and perspective cameras.
| Format or workflow | Support |
|---|---|
| DWG | Read and write; versioned save targets from R14 through 2018 |
| DXF | Read and write; versioned save targets from R14 through 2018 |
| BAK / SV$ | Open drawing backups and autosave files |
| OBJ | Import polygon meshes |
| LandXML | Import CgPoint survey points |
| STL | Export 3D mesh data |
| STEP AP203 | Export 3D mesh data |
| Plot layouts and selected geometry on desktop | |
| CSV | Extract entity property data |
| CTB / STB | Load and edit plot style tables |
Use the web app for immediate access with no installation. Drawings are selected through the browser and saved as local downloads.
Use the desktop application for native file associations, file-manager thumbnails, system printing, PDF output, external plugins, command scripts, and headless automation. Release builds are available for Windows, Linux, and Apple Silicon macOS.
Download all current packages from the latest release.
Choose one of these signed x86-64 packages:
OpenCADStudio-*-windows-x86_64-installer.msi — recommended installer with Start Menu shortcuts, DWG/DXF file associations, and drawing thumbnails.OpenCADStudio-*-windows-x86_64-portable.exe — standalone application; no installation required.Download the x86-64 AppImage, make it executable, and run it:
chmod +x OpenCADStudio-*-linux-x86_64.AppImage
./OpenCADStudio-*-linux-x86_64.AppImage
Or install it as a Flatpak from FlatPark, which installs the official AppImage and follows new releases:
flatpak remote-add --if-not-exists flatpark https://dl.flatpark.org/flatpark.flatpakrepo
flatpak install flatpark io.github.HakanSeven12.OpenCadStudio
The Flatpak opens and saves drawings through the file chooser. External references and underlays that point at other files need home access:
flatpak override --user --filesystem=home io.github.HakanSeven12.OpenCadStudio
The published macOS package supports Apple Silicon:
OpenCADStudio-*-macos-arm64.dmg.OpenCADStudio.app into Applications.The application is ad-hoc signed but is not currently notarized by Apple.
Open CAD Studio can follow the system language or use any of these 21 interface languages:
> Arabic · Brazilian Portuguese · Bulgarian · Czech · Dutch · English · Finnish · French · German · Greek · Hindi · Hungarian · Italian · Japanese · Korean · Polish · Russian · Simplified Chinese · Spanish · Traditional Chinese · Turkish
Change the language from the application settings. The browser version also uses the browser's preferred locale when System is selected.
Requirements:
On Ubuntu or Debian, install the native dependencies with:
sudo apt update
sudo apt install libgl1-mesa-dev libx11-dev libxcursor-dev libxi-dev \
libxrandr-dev libxkbcommon-dev libwayland-dev libfontconfig1-dev \
libfreetype6-dev
Then build and run:
git clone https://github.com/HakanSeven12/OpenCADStudio.git
cd OpenCADStudio
cargo build --release --bin OpenCADStudio
The resulting binary is written to target/release/OpenCADStudio (OpenCADStudio.exe on Windows).
Install the WebAssembly target and build tools once:
rustup target add wasm32-unknown-unknown
cargo install trunk wasm-bindgen-cli
Start the development server:
trunk serve
The desktop binary supports one-shot conversion, a persistent headless server, and a client-neutral MCP endpoint for AI applications:
OpenCADStudio --export input.dwg output.dxf
OpenCADStudio --export input-r12.dxf output.dwg --target-version R14
OpenCADStudio --serve
OpenCADStudio --serve --port 4242
OpenCADStudio --mcp
The automation server exchanges one JSON object per line over standard input/output or a local TCP socket. The self-contained MCP endpoint exposes the live desktop editor through the same tools to every compatible client. Its audit and save_verified operations check an explicit DWG/DXF target version, lossy records, raw DXF handle references, reopen the output, compare its semantic manifest, and return a SHA-256 hash. To connect a client, configure it to launch OpenCADStudio --mcp. See the MCP control guide.
Desktop plugins run in separate processes and communicate with the host through the versioned plugin API. The browser build does not load native plugins.
Bug reports, focused pull requests, translations, documentation improvements, and plugin contributions are welcome.
Application translations live in locales/*/opencadstudio.ftl; source labels map through
src/locale_catalog.rs. After editing translations, run python3 scripts/export-locales.py
to refresh web and desktop packaging labels. Validate with python3 scripts/test_site.py
and cargo test --lib i18n::tests.
