A CAD design tool for coding agents (free + open source)
agentcad is an innovative open-source CAD design tool tailored for coding agents, combining AI and 3D modeling to streamline the creation of manufacturable parts. It allows users to give prompts, sketches, or images to AI agents like Claude or Codex, which then generate precise build123d or CadQuery scripts. The platform goes a step further by automatically checking the generated geometry for errors, ensuring watertight and dimensionally accurate models. Its interactive viewer, along with exported STEP, STL, and GLB files, enables users to inspect, modify, or prepare parts for 3D printing or manufacturing. What sets agentcad apart is its integration of AI-driven code generation with rigorous self-validation, reducing errors and saving time in the design process. This tool is ideal for developers, hobbyists, or engineers seeking an open-source solution that combines AI capabilities with robust 3D modeling features.
