I am designing a 6layer board, using layers 2 and 5 as VDD and GND pours respectively. Every time I hit ratsnest, it reduces airwires (for things connected to 2 and 5) but also fills the screen with copper. It is very annoying trying to look through the copper to see traces below and above it. I keep going to the edge of the board to move the polygon to lose the copper pour but not bring back the airwires (have done about a million times, very aggravating). Is there a way to use ratsnest, have it reduce airwires (for things connected to pours), and not fill in the board? If I turn off ratsnest processes polygons in Options/Set/Misc, it will not make any connections to either layer 2 or 5. Using EAGLE 6.5.0 professional. Thanks.
