Not perfectly relevant but build123d docs have an example using sympy as part of solving constraints for a design. https://build123d.readthedocs.io/en/latest/tttt.html#t-24-cu...

Ok here is my result, which matches up well with the examples I have found from McMaster Carr. Note that not all STEP importers are robust enough to deal with files from OCCT based CAD packages. As I mentioned previously there are transitio

build123d can absolutely accomplish this. I downloaded a STEP file of a self-reversing (diamond) thread part from McMaster Carr for analysis. I will reply when I finish a recreation of it. Based on my analysis of the STEP I most likely will

Yes, AFAIK you are correct that SCAD is incapable of outputting clean STEP files.

Also worth looking at this project https://gitlab.com/dmytrylk/solve123d which adds constraints on top of build123d using a jax-based numerical solver.

This feature technically already exists in build123d + OCP CAD Viewer (ocp_vscode). You can click a feature in GUI and it will copy the index to clipboard, you can then apply e.g. fillets to it on the code side. See here https://

The definition of an ellipsoid is that it can have three independent radii. A revolved ellipse only has two independent radii. If only two independent radii are needed then yes I agree with you, but I wanted to provide a fully qualified ans

Neither Fornjot nor Truck are ready for general use as a BREP CAD kernel.

Here's an ellipsoid in build123d using geometric transformation of a sphere: from build123d import * mat = Matrix([[2,0,0,0],[0,1.5,0,0],[0,0,0.5,0]]) ellipsoid = Sphere(100).transform_geometry(mat) Also, FYI build123d

>OpenSCAD however fails spectacularly for any kind of complex filetting situation when compared to tools like Fusion or even FreeCAD (FreeCAD's UI is an abomination though). build123d[1] is based on the same kernel as FreeCAD and ha

You should really look at build123d -- it is a full CAD package including 3D but it also treats 1D and 2D as first class citizens. Your idea about drawing lines is already supported in build123d: m1 = Line((0,0),(0,24)) # vertical

Fillets in BREP software are so much more complex than this, your statement is a huge oversimplification.

Have you taken a look at the build123d "algebra API" yet? It is intended to be near zero magic without any of the with blocks from the "builder API". There are algebra and builder API versions of all of the introductory
