You can explain what you want, I used GSX pro 3D Editor in v3.71. and the manual to measure Jetway rootfloor. That's all I did.
You titled this thread as "Editing
Pax Waypoints in 3D", that is why I pointed out the relevant page of the manual that HAS been updated and list the changed keys, which is in the chapter named "Editing
Pax Waypoints".
Now you are saying you were not really editing Pax waypoints as you said you did, you are instead measuring jetway floors then yes, THAT's the page that hasn't been updated in the manual, but it will be of course in the next update.
But that's not the point, the point is you can't expect the 120+ (now 150) pages manual would always be updated to the latest updates (which other game is, really ?), and when in doubt, it goes without saying the release notes are always taking precedence.
