I have updated the code and I think the geometry manipulation is now close. Please note the move multiple tracks key press that I have coded up is Alt-M, not Ctrl-M. Just need some help on adding tracks to a pcb so that the solution can be fully visualised. There are probably a few other corner cases that need handling yet, but its probably useable once the track adds are fixed.
