I recently added a .dxf export feature to my boat hull design app but it didn’t work. I wanted a wire frame of the hull that I could open in my CAD program for further development. I showed ChatGPT the file that came from the exporter Codex made and it figured out that Codex had created an AC1015/AutoCAD 2000 file but my CAD program was expecting a newer R12/AC1009 format. It then wrote the prompt I needed for Codex to rewrite the export feature and it now works perfectly! New skill learnt: Use ChatGPT as a problem solving partner for Codex!
