Thanks.. but are you trying to get closer to RHINO MAKE 2D command??
If you work a litle bit more, you gone win on this. I which you could add choose layers when projection are done, because it is very dificult to diference VIEW LINES from a CUT Line. And try to get better performance, because i try it on a small example and it took like 1 minuto do complete. (and i have a great machine workstation and SU 2015 x64bits)
Thanks
