Isn’t the python based build123d the current best CAD in code solution? The problem with OpenSCAD is that it cannot export solid geometry, just a final mesh.

More broadly, I was genuinely shocked to realize, when I was playing with it, that there is no cross CAD file format that captures even simple design concepts like “this hole is aligned to the center of this plate” or even “this is a 2mm fillet”. STEP (the file format) mostly just captures final geometry.

I think CAD people just … redesign the part again if they need to move from say Fusion 360 to FreeCAD or whatever. How do they live like that?!

STEP is capable of capturing what you describe, it is down to the "user group" of customers of the CAD vendors to ask for it to be implemented by each CAD system in terms of what they import and export.

We put in for some funding for the next edition of STEP AP242 for me to be able to work more closely with the user group to improve this area.

That's awesome! Yeah it seems strange to me that we don't have a standard way of tracking how a model is built up and parameterized (basically Fusion 360's history mode). I'd naively assumed that this was a solved problem in the CAD world - given the whole point of parametric CAD is to be able to easily tweak the distance between two points and have the whole model update.
