I'm writing a program the reads schematic library symbols, and I'm having hard time understanding how arcs are drawn. Taking, for example, the Antenna_Shield symbol from device.lib. This symbol contains two arcs:
A -1 -73 32 -882 1242 0 1 0 N 0 -105 -20 -45 A 1 -73 32 -918 558 0 1 0 N 0 -105 20 -45 Both arcs start at approximately the same angle (-90 = 270 degrees) and end at two different angles - the first at 124 degrees, the second at 56 degrees. When the symbol is drawn, the first arc is drone clockwise while the latter is drawn anti-clockwise. So, how is it possible to determine the direction of the arc? Avishay.
