We are writing a program that is placing some different objects (like buildings, antennas...). We are also placing power lines, but for the cables pitching we need to know the altitudes from the power lines (e.g. if two power lines have different altitudes, we need to calculate the pitching from their distance and their height). So is there any chance to read altitudes from specific coordinates. If yes, do you need simconnect for this or is that information stored somewhere in a kind of database?
