Limo CAD is a free, open-source, local-first mechanical CAD software built with Rust, Open CASCADE, and Bevy. It provides full parametric modeling capabilities where constrained sketches drive solid features, ensuring models remain fully editable throughout design changes. Equipped with a built-in Model Context Protocol (MCP) server, Limo CAD allows AI agents to inspect, construct, and modify parts and assemblies side-by-side with users using standard editable history. Storing entire projects in a single local file, it delivers reliable mechanical design, assembly kinematic checks, drawing generation, and versatile standard export formats without cloud dependencies or paid tiers.
