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.* "Build123d: A Python CAD programming library" (2023) https://news.ycombinator.com/item?id=37576296 https://news.ycombinator.com/item?id=37576296 build123d docs > Tips & Best Practices: https://build123d.readthedocs.io/en/latest/tips.html https://build123d.readthedocs.io/en/latest/tips.html BREP: Boundary representation: https://en.wikipedia.org/wiki/Boundary_representation https://en.wikipedia.org/wiki/Boundary_representation Manim, Blender, ipyblender, PhysX, o3de, [FEM, CFD, [thermal, fluidic,] engineering]: https://github.com/ManimCommunity/manim/issues/3362 https://github.com/ManimCommunity/manim/issues/3362 NURBS: Non-Uniform Rational B-Splines: https://en.wikipedia.org/wiki/Non-uniform_rational_B-spline https://en.wikipedia.org/wiki/Non-uniform_rational_B-spline NURBS for COMPAS: test_curve.py, test_surface.py: https://github.com/gramaziokohler/compas_nurbs https://github.com/gramaziokohler/compas_nurbs : > This package is inspired by the NURBS-Python package, however uses a NumPy-based backend for better performance. > Curve, and Surface are non-uniform non-rational B-Spline geometries (NUBS), RationalCurve, and RationalSurface are non-uniform rational B-Spline Geometries (NURBS).
