Hi,

Since the power planes are negative, do you know any way to draw tracks on these layers? I know this is not a good idea but I need it at some point.

Thanks.

Why don't you use signal layer with traces and polygons?
When board become complex and density become high I always do that with power planes. but try not to do it with GNDs. Once I had board with all layers to be signal, but I tried to place polygons or wide GND traces under signal traces and not overlap signal lines.

But, I do no think there is an easy way to do what you want in negative layers.

I do not use negative layers to draw tracks.

@@brs the iMX6 Rex board used signal layers for power(polygons) ,otherwise the iMX6 Rex Development Baseboard used power planes.

Yeah, the module used polygons because it uses uVias and short tracks on GND layers. Baseboard doesn't have any short tracks so we could use power planes.
