This will be hard to explain: I'll try my best:
When creating multiple stop positions, you have to look at the ruler. Everyone knows this, but the ruler is very hard to use. You have to get your camera in a perfect position. Then 50% it will still be wrong. So you for to restart the console, reposition you aircraft 3 times pre gate to get the right number
I good solution would be to create a visual Marker. After you edit the stop position (in the editor) you would click F4 to get to this new marker. It would act like a passenger waypoints in a way. You move the passenger waypoints up and down, to get the high for custom Jetways highes.
You would only be able to move the maker on the y axis. You would move it to the second stop positions. Above it would say X.XX (what ever number that would be on the ruler bellow) Then you write it down in your .py file. You move the marker to the next stop positions. Then it would give you the exact number on the ruler.
This is a 100% times easier that before, and would make profiles a lot for realistic, and would save us profile creaters alot of time!
Hope this makes scene...
