3D CAD Converter

ChatGPT plugin

Convert CAD and 3D files

View in ChatGPT directory

Convert CAD and 3D model files (STEP, IGES, STL, OBJ, FBX, glTF, 3MF) on your Windows PC, for 3D printing, the web or another CAD tool. 3D CAD Converter is a Windows desktop app for converting STEP, IGES, STL, OBJ, FBX, glTF, 3MF and other 3D/CAD files; this skill teaches the agent its command-line tool (cadconvert), so you ask in plain words and the work runs on your own PC, on your own files, with nothing uploaded. It needs 3D CAD Converter installed (https://www.contenta-software.com/3dcadconverter/download.php). In Codex the agent runs the commands for you; in ChatGPT it tells you which command to run.
