Now the point: I'm using MyTraffic 5.1b from Aerosoft and I have a minor issue: no enough place to move without touching other planes (see pictures). Would it be possible for you fixe that?
The yellow taxiway lines are obviously at their real world positions, so is the rest of the airport, so there's nothing to fix. Your issue, seeing from the screenshots, is that you are using a large airplane in a place were is not supposed to be. Heavies usually park at the 17, 18 and 19 gates.
