I have some connections in my single-sided PCB which could benefit from a plane especially all connections to power and all connections to ground. I can easily create a polygon for only one plane (for example to intelligently flood the remaining bare spots (areas with no copper) of the PCB with ground), however I want to also be able to fill applicable bare spots with power (vcc). I tried creating a polygon named gnd then on top I tried creating a polygon named vcc and after running rats nest, it seems that the gnd and vcc are shorting each other. If I play around with the rank values, then either gnd or vcc will fill the bare spots, but not both.
Is there a way I can have both a gnd and vcc plane without resorting to non-overlapping of plane creating and without making each plane use only a small portion of the board?
