Build123d is a python-based, parametric, boundary representation (BREP) modeling framework for 2D and 3D CAD. It's built on the Open Cascade geometric kernel and allows for the creation of complex models using a simple and intuitive python syntax. Build123d can be used to create models for 3D printing, CNC machining, laser cutting, and other manufacturing processes. Models can be exported to a wide variety of popular CAD tools such as FreeCAD and SolidWorks.

Build123d could be considered as an evolution of CadQuery where the somewhat restrictive Fluent API (method chaining) is replaced with stateful context managers - e.g. with blocks - thus enabling the full python toolbox: for loops, references to objects, object sorting and filtering, etc

Is there a jupyter-cadquery -like tool for build123d?

"Render with Blender and/or o3de" https://github.com/bernhard-42/jupyter-cadquery/issues/99

Is there a blenderGPT-like tool trained on build123d Python models?
