## FAQ

### How can I use the server without an account?

The hosted server requires no account or API key to connect.

### What are the rendering limits for a design?

Each render is limited to 100,000 steps, 100 parts, and 10 sheets.

### Does a successful render guarantee the parts will fit?

No, a successful render does not guarantee part fitment; you should cut a test piece in your material first.

### Can I run the server locally to keep my designs private?

Yes, you can run the server locally using Node.js 20 or newer so that designs never leave your computer.
