I’d love to see this. It was a frustrating learning curve for me to realize that I couldn’t STEP export work from OpenSCAD to something like Fusion.

Build123d is much better (supports STEP export and import) but a tightly integrated CAD frontend would be ideal!

PythonSCAD now has STEP export:

Wait to usefully import and export STEP you need to be BREP based right? I thought SCAD’s engine was fundamentally incompatible (only really one open source BREP engine out there - OpenCascade)

Pretty much, that's why for DXF export I rolled my own:

(shows a DXF w/ arcs)

(shows a .py file for making DXFs)

See the PDF at the top level for more information.

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