Getting started

Install CoCAD

1. Get the installer from the download page. CoCAD runs on Windows 11, 64-bit, on an Intel or AMD processor. Other versions of Windows have not been tested.
2. Run it. Windows names the publisher as CoCAD LLC. Windows may also warn you about a new download. Check that publisher name before you continue.
3. Read and accept the license. Installing and running CoCAD does not need an internet connection.

With no License File, CoCAD runs as CoCAD Free, with no account and no sign-in. CoCAD Free is for personal, non-commercial use. Commercial use needs a CoCAD Pro license.

Start your first part

Start CoCAD from the Start menu. The window opens on a card that asks What are we making? Type a name and press Start. Help > Take the tour walks you through the window, and the guide folder beside CoCAD has a ten-minute getting-started page.

Connect an AI assistant

This is optional. Open Settings > AI or Help > Connect AI to connect Claude, Cursor or another MCP client, and it works on the same model you see. The MCP command reference lists every command it can use.

Updates

After a notice the first time you run it, CoCAD checks for updates each time it starts. You can turn that off, and check by hand, in Settings > Updates.
