NX to glTF (GLB) format

Looking for a way to export from NX to glTF format. Facebook now allows glTF formats (GLB/glTF) to be included on your feed so you can have a 3D part spin around within a window on your browser. The glTF format is explained on Wikipedia as the JPEG of 3D. Of course, you're limited to 3Mb so pretty small.

I found this strange little tool online that maps CAD translation possible conversion paths. https://www.cadforum.cz/cadforum_en/formats.asp?fmtin=16&fmtout=80 Showing a possible path through Autodesk products.

I can export a 3MF file from NX12.0.2. If I have a sub-division model, I can export an OBJ file.

Thank you...
