Alberto,
Thanks for the comments.

With a dxf file, in a CAM program, you can program your fine line

Are you sure you want to do this? Is it for aesthetic reasons or
because of better isolation?
Besides thrashing large amounts of bits and requiring hours of work it
won't make your pcb's work better; if you need good isolation it's
better to insert several traces between the ones you want to isolate.
I would like to remove floating copper for RF and static electricity
reasons. The 'pcb' program thinks that floating copper is enough of
an issue to have code to detect and remove it.
I have seen blogs where guys take tweezers and rip the floating
copper off the boards they have isolation milled. I would like to
have the cnc machine do it. I agree that it will destroy lots of
bits, though. It is a trade-off between disposable etching chemicals
and disposable bits.
