# vcad
Open-source parametric CAD for the AI era.
**[Try it now →](https://vcad.io)**
## Features
- **Modeling** — Primitives, booleans, fillets, chamfers, shell
- **Sketching** — 2D constraints, extrude, revolve, sweep, loft
- **Assembly** — Parts, instances, joints, forward kinematics
- **Simulation** — Physics with Rapier3D, gym-style RL interface
- **Import/Export** — STEP import, STL/GLB/STEP/DXF export
- **Rendering** — Direct BRep ray tracing + tessellated mode
- **Cloud** — Supabase sync with Google/GitHub auth
## Use vcad
### Web App
Visit [vcad.io](https://vcad.io) — no install required.
### CLI
```bash
cargo install vcad-cli
vcad export input.vcad output.stl
vcad import-step input.step output.vcad
```
### MCP Server (AI Agents)
The MCP server lets AI agents create and manipulate CAD models:
```bash
npm install -g @vcad/mcp
```
Tools: `create_cad_document`, `export_cad`, `inspect_cad`, `gym_step`, `gym_reset`
### Rust Library
```rust
use vcad_kernel::Solid;
// Create a box with a hole
let solid = Solid::cube(100.0, 60.0, 20.0);
let hole = Solid::cylinder(10.0, 25.0, 32);
let result = solid - hole;
// Export to mesh
let mesh = result.to_mesh(32);
```
See [crates/vcad-kernel](crates/vcad-kernel) for the full API.
