Formed stickers use edge lines. However, flat stickers don't. The parts library spec says the following (emphasis added):
So, cylinders used on the edges of that box would be cyli2, as indicated.
Quote:The sticker should be modelled as a 0.25 LDU thin box (or whatever shape sticker is in), without any edge lines (type 2 lines), and coloured with main colour 16. The sticker should be oriented such that the top face is at -0.25 Y and parallel with the X-Z plane. The pattern with the hardcoded colours is on the top face.
