hi, my first try at BTB . i have a full picture as background (real live track) for my track (pictures added together from screen shots off google earth, to make one big picture). i started by placing nodes (two nodes per corner) and moved them around (also stretching/moving the node handles) till the track layout was +- correct. but the track layout is still not 100%, as per real life/background picture. so what am i to do to get the top view 100% as per background picture? then after that can i start with the elevations of the track? help greatly appreciated.
