CodeToCAD

CodeToCAD is a vendor-agnostic framework that lets engineers and AI agents define mechanical and electrical designs in one Python language, then federates the script to the modeling or design application automatically. The README quick start builds a cup from a cylinder, shells it, assigns a material, and exports an STL, or runs the same design through an interactive CLI that generates Python part files for every action.

Parts and assemblies carry 6-dof locations, constraints, materials, and fasteners, and the framework can generate dimensioned third-angle technical drawings as editable 2D parts. The same design federates to Build123D for real OpenCascade solids with native STL and STEP export, or to Blender meshes, and assemblies can be simulated in PyBullet or MuJoCo or analyzed with CalculiX finite elements.

The ECAD side describes circuits as components and nets, then federates them to schematic capture and SPICE simulation through skidl and ngspice, including KiCad netlist export. Sensors and actuators bind to a microcontroller definition, and a web app control panel can drive the same hardware or an emulated microcontroller.
