SpletPOLYGONS are needed for a number of different tasks in a PCB design: As a ground plane under RF lines like microstripe or coplanar lines. As a power plane (for example Vcc) and/or groundplane, to create a low resistance connections. Generally to make a low resistance connection for tracks that carry a high current. SpletInPolygon(简写为 InPoly) 是指对象本身是 polygon 的一部分(例如定义 polygon 并覆铜之后所产生的线条)。 例如设定覆铜间距规则的时候就要用 InPolygon 来作为条件,因为 … the keymaster play
