Antimony, a code-based CAD tool rooted in Lisp-machine ideas rather than drafting-table workflows, has seen maintenance taper since around 2016, though a more actively maintained fork called Stibium is now available. Discussion around the piece highlights renewed momentum in code CAD and AI-driven CAD projects, citing OpenSCAD’s long-awaited release candidate, PythonSCAD, CADquery, Build123D, and Halfspace. Commenters debated the practicality of code-based parametric CAD while noting desired features like SolveSpace-style 2D sketching and fillets/bevels.
