## 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](https://github.com/HakanSeven12/OpenCADStudio/issues).
## Highlights
- **Native drawing workflow** — open, edit, recover, and save DWG and DXF files without a conversion service.
- **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.

## Desktop or web
Use the [web app](https://www.opencadstudio.com) 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](https://github.com/HakanSeven12/OpenCADStudio/releases/latest).
### 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:
> Arabic · Brazilian Portuguese · Czech · Dutch · English · Finnish · French · German · Hindi · Hungarian · Italian · Japanese · Korean · Polish · Russian · Simplified Chinese · Spanish · Traditional Chinese · Turkish
The server exchanges one JSON object per line over standard input/output or a local TCP socket. See the [automation guide](docs/automation/README.md) and the included [Python client](docs/automation/ocs.py).
## 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.
