I have already posted a question, how to edit the GND plane shape of my board in order to remove a part of the GND plane. Well, I attached my gerber file and I hope that someone tell me if that's OK like this or no? I would like to know if I sent the gerber file like this, does the manufacturer will understand that the green zone means that it's a non copper zone or no?
If the PCB manufacturer realizes that the gerber plot is meaned as negative layer, the solid area will be a cut-out. I presume the negative layer point will be clear when looking at the other copper layers and drills. In addition it should be contained in a job description.
