I don't think it's plagiarized, nor would I pirate a copy. The workflow through the Gemini made app is way better (it's customized exactly for our inputs) and totally different than how the CAD program did it. So I wouldn't pirate a copy not even because our business runs above board, but also because the CAD version is actually also worse for our use. This is also pretty fringe stuff, cnc machine files from the 80's/90's.

Part of the magic of LLMs is getting the exact bespoke tools you need, tailored specifically to your individual needs.
