Maybe I am late at this, but I found that the new version of ChatGPT Codex 5.4 (pro version) is finally capable of generating complex Fusion 360 designs directly from prompts.
I have just spent about an hour working with it on a parametric frame design with snapping cantilever keys suitable for 3D printing. The resulting script is roughly 2,700 lines long, and, quite honestly, I am in awe of what it managed to produce. Just paste the text of the attachment into a F360 script canvas and try it out for yourself- you may be amazed!
For those of us who want to get useful things done but are only moderately proficient in parametric drawing, this feels like a genuine game changer. It does not replace engineering judgment, of course, and the output still needs refinement. But it dramatically lowers the barrier to building fairly sophisticated, editable, parametric models.
What impressed me most is not just that it generated geometry, but that it generated something genuinely usable: a parametric design with functional snapping features that can be adapted and iterated further. For amateur makers, researchers, and anyone who needs practical custom parts without being a full-time CAD expert, this seems a big deal!
