Shortened translation: What kind of graphical helpers are planed? A tool to display the line-heights would be great (good example described).
We are aware of the problem with the inaccurate visualization of terrain heights. Our solution is some kind similar to your suggestion. While planning your track the terrain heights are displayed and you’re able to see the terrain changes without building anything.
We have a few graphical overlays planned, for example height curves and traffic-displays. A display mode to display the zone of influence is not possible with our simulated passengers, the player has to study the city structure and create the best possible layout without this helper.
