      What it ships

        Your drawing never leaves this browser

        Nothing is uploaded or stored on our servers. Parsing and rendering happen in this tab.

        Features

        Built for privacy, portability, and product teams.

        Every capability is designed around a single principle: serious CAD work should be possible without standing up a CAD server.

        Platform modules
