CadQuery

CadQuery is a powerful Python-based framework for creating parametric 3D CAD models. It leverages the robust Open CASCADE Technology (OCCT) kernel, enabling advanced modeling capabilities such as NURBS, splines, and surface sewing. With CadQuery, you can write concise scripts to generate complex models, making it ideal for engineering and scientific applications.

Key benefits include:

• Python Integration: Utilize Python's extensive libraries and IDEs.
• High-Quality Exports: Output models in STEP, STL, and more.
• Advanced Features: Support for fillets, lofts, and nested assemblies.
• Open Source: Modify and extend with ease.

CadQuery is perfect for those who need a flexible, script-based approach to CAD modeling without the constraints of a GUI, although options like CQ-Editor and JupyterLab are available for visualization.
