Hello,

Thanks for your answer.

But I did not succeed yet in making a hole master Gerber.
How can I do it using CAMtastic ?
Once I will have made a hole master Gerber, will it be possible to stack the
hole master over the original PCB ? And how ?

I guess I will have for example to invert my PCB colors (copper will then
appear in white on black), them stack my hole master layer (holes appearing
black on white) over it, then invert colors of the whole PCB.
Is it the right way ?

Thanks in advance,
