One thing you can do is to define the class of the signal as

If PCBGCODE pays attention to that, then you're fine. The traces will
be autorouted far enough away, and if you're hand routing the board,
the DRC check will whine at you.
If not, then just draw the ground plane to exclude the area, or check
how eagle does "keep outs and restricts". That might help.
I’ve had the same problem before, solved it by adding my own gcode at the end of the milling process – used a 2mm carbide end mill to do the milling, removes large areas quickly.

Subject: [pcbgcode] How to etch a powerplane with pcb-gcode? #etch
I have to make a pcb where are power traces also beside signal traces.
The power traces are for the main AC/230v which are going into a relay then out on two outputs.
Everything is fine, but! I wish to mill all the copper around the power traces so I can get a copper less clear distance between
the traces so it could not happen does a spark is jumping over the traces.
When we mill our pcb with cnc, we can setup the clearance between the traces, but I don't have to remove the whole
copper from the pcb, just in the area where the power traces are.
I don't know if I explained enough correct but here is a simple picture about my problem:
The N$9, N$10 and N$12 are the power traces.
I wish to remove the copper area what I marked with some green drawings.
Any idea how to achieve this with the pcb-gcode plugin for Eagle?
