We must then ask ourselfs:
I don't understand what you want. These are the only important questions, the others are secondary.
This will not affect you who want to continuing with todays workflow. It just opens up for us who want to go forward and upward plus include global big corp users.
No it don't! This helps only the small group of engineers who work normal with SW, NX, Creo and related software. All engineers that normally work software for architecture, environmental, civil etc they don't need this
That's not correct. For architecture it's super important that the master project has a absolute zero / master zero related to a coordinate system. Especially when placing multiple buildings on a buildingplot. Or doing urban planning. If you want to relate a model to the real world it's importand that you can select the right coordinate system. There are multiple systems used in the world, see https://epsg.io/. And for our country we use https://epsg.io/7415, rijksdriehoekstelsel. For example Sketchup doesn't have this. It's always a hell to align multiple imported files.
