1. post_stl_export_to_host() now opens the CAM page with window.open(..., '_blank') instead of window.location().set_href() - the latter navigated the CAD editor's own tab away, which tears down its WASM/GPU/worker context. Going back afterward doesn't reliably restore it, and a user who then hit Save on the broken restored state would silently overwrite the real file with whatever that broken state held. A new tab leaves the original completely untouched. (User report: CAM froze on load, then going back and saving "blanked" the file.) 2. save_with_default_format(): a plain Save (not Save As) on an already-loaded document used to ALWAYS serialize using the hardcoded default format (DWG 2018), ignoring what the document actually was - confirmed live via a real corrupted attachment (a .dxf that, after one Save, contained binary DWG bytes under its original .dxf name and filename, size dropped ~11.6MB -> 1.5MB). This is a pre-existing upstream gap, not something the CMMS patches introduced - native builds never hit it because on_save_file()'s native branch has an early-return for "just re-save to the known path" that preserves the current version; web has no equivalent and always fell through to this function's unconditional default. Extended the same format-preservation logic recovery-saves already use to also apply whenever the document has a known current_path (i.e. it's not actually a fresh, never-saved drawing). |

Open CAD Studio
Open-source 2D drafting and 3D modeling for desktop and web, built with Rust.
Launch the web app · Download the desktop app · Join the discussion
Overview
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.
Highlights
- Native drawing workflow — open, edit, recover, and save DWG and DXF files without a conversion service.
- Precise 2D drafting — lines, polylines, curves, splines, hatches, object snaps, tracking, layers, blocks, and external references.
- Documentation tools — text, dimensions, leaders, tolerances, tables, model space, paper space, viewports, and plot styles.
- Kernel-backed 3D modeling — solid primitives, extrusion, revolution, sweep, loft, Boolean operations, and ACIS entity tessellation.
- GPU rendering — accelerated 2D and 3D viewports through
wgpu, with orthographic and perspective cameras. - Extensible workflows — native plugins, command scripts, headless conversion, and a line-based JSON automation API.
File workflows
| 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 |
Desktop or web
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.
Install
Download all current packages from the latest release.
Windows
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.
Linux
Download the x86-64 AppImage, make it executable, and run it:
chmod +x OpenCADStudio-*-linux-x86_64.AppImage
./OpenCADStudio-*-linux-x86_64.AppImage
macOS
The published macOS package supports Apple Silicon:
- Download
OpenCADStudio-*-macos-arm64.dmg. - Open the image and drag
OpenCADStudio.appinto Applications. - If Gatekeeper blocks the first launch, approve the app from System Settings → Privacy & Security.
The application is ad-hoc signed but is not currently notarized by Apple.
Languages
Open CAD Studio can follow the system language or use any of these 20 interface languages:
Arabic · Brazilian Portuguese · Bulgarian · Czech · Dutch · English · Finnish · French · German · 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.
Build from source
Desktop
Requirements:
- Git
- Current stable Rust toolchain
- Platform graphics and font development libraries
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).
Web
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
Automation
The desktop binary supports one-shot conversion and a persistent headless server:
OpenCADStudio --export input.dwg output.dxf
OpenCADStudio --serve
OpenCADStudio --serve --port 4242
The server exchanges one JSON object per line over standard input/output or a local TCP socket. See the automation guide and the included Python client.
Plugins
Desktop plugins run in separate processes and communicate with the host through the versioned plugin API. The browser build does not load native plugins.
