Export for Production (Etchable SVG) in CNC router

I understood.
After reading a CopperCAM manual written in Portuguese (Brazil), downloaded from the Internet (CopperCAM website has no manual), I'm thinking that for a Gerber generated by Fritzing work in CopperCAM the PCB of this Gerber can not contain copper fill (Fritzing -> Routing -> Ground Fill -> Copper Fill).
We must let the Copper Fill (or Ground Fill) is created in CopperCAM.
Am I right?
