The Manhattans.vbs script will report pin to pin and the resulting total manhattan length (disregarding topology and pin order) of each net on the board, or, each selected net on the board. If selecting nets to process, a user layer named "Manhattans" is created and the manhattan skyline is drawn on the layer. Each skyline line serves two points using an "L" shape line. This is shown in green in the snapshot below. The algorithm sorts all pins of a net in the x, then sorts all common x pins in the y to obtain its results. This will generate a LogFiles\Manhattan.txt so that it is accessible by the FileViewer.
