agreed, though I can see it making some sense in those specific situations, e.g.: >PCL reduces cost by 86% on interior curved lines layout at Vancouver airport for random bits of complicated-shape fashion in a giant flat open area, I can see how it could almost immediately pay for itself. that said... at that point it's probably competing with "we put a projector on the ceiling for a day, and went over the lines with chalk". which is quite cheap.
