High: stateful vs. stateless

  • stateful: photoplotter (gerber example)
  • stateless: unordered list (pcb, pcb-rnd, bxl, eagle wires, kicad)
  • special cases and examples:
    • polygon: different closings
    • board contour
    • polylines per net/conn (PADS ASCII):
      • dangling endpoints
      • multiple 2-nets, T junction
      • polygon connection
      • no-net lines become special case!
