# Open CAD Studio
|
||
|
||
OCS is a CAD application for 2D drafting and 3D modeling, built with Rust. Reads and writes DWG and DXF files natively. Also has a web version now!
|
||
|
||
## OCS Web try it in the browser: https://hakanseven12.github.io/OpenCADStudio/

## Installation
|
||
|
||
### Linux (AppImage)
|
||
|
||
Download `OpenCADStudio-*-linux-x86_64.AppImage` from the [latest release](https://github.com/HakanSeven12/OpenCADStudio/releases/latest), then:
|
||
|
||
```bash
|
||
chmod +x OpenCADStudio-*-linux-x86_64.AppImage
|
||
./OpenCADStudio-*-linux-x86_64.AppImage
|
||
```
|
||
|
||
No installation required — runs directly on any modern Linux distribution.
|
||
|
||
### Windows
|
||
|
||
Download `OpenCADStudio-*-windows-x86_64.exe` from the [latest release](https://github.com/HakanSeven12/OpenCADStudio/releases/latest) and run it directly. Windows SmartScreen may show "Windows protected your PC" because the binary is not yet code-signed — click **More info → Run anyway**.
|
||
|
||
### macOS (Apple Silicon)
|
||
|
||
Apple Silicon (M-series) only; Intel macOS isn't built. The app is ad-hoc signed but **not Apple-notarised** (notarisation requires a paid Apple Developer ID), so macOS Gatekeeper guards the first launch. Pick whichever path is easiest:
|
||
|
||
**Option A — Homebrew (recommended):**
|
||
|
||
```bash
|
||
brew install --cask --no-quarantine \
|
||
https://raw.githubusercontent.com/HakanSeven12/OpenCADStudio/main/packaging/homebrew/open-cad-studio.rb
|
||
```
|
||
|
||
`--no-quarantine` lets Gatekeeper skip the unsigned-app prompt. See [`packaging/homebrew/`](packaging/homebrew/) for publishing this as a `brew tap`.
|
||
|
||
**Option B — manual .dmg:**
|
||
|
||
Download `OpenCADStudio-*-macos-arm64.dmg` from the [latest release](https://github.com/HakanSeven12/OpenCADStudio/releases/latest), open it, and drag `OpenCADStudio.app` to `/Applications`. If the first launch is blocked, clear the quarantine flag once:
|
||
|
||
```bash
|
||
xattr -dr com.apple.quarantine /Applications/OpenCADStudio.app
|
||
```
|
||
|
||
On older macOS you can instead right-click `OpenCADStudio.app → Open` and confirm; on macOS Ventura and later, approve it via **System Settings → Privacy & Security → Open Anyway**.
|
||
|
||
### Build from Source
|
||
|
||
Requirements: Rust 1.75+
|
||
|
||
```bash
|
||
git clone https://github.com/HakanSeven12/OpenCADStudio.git
|
||
cd OpenCADStudio
|
||
cargo build --release --bin OpenCADStudio
|
||
./target/release/OpenCADStudio
|
||
```
