Subject: Re: [Homebrew_PCBs] drill holes in gerber file -how can it be done

In Target there is also a function like this to only print small
starter holes. Very useful for me.

It can probably be faked by setting the hole dia. really small, but if
you order PCBs from those files later you better not forget to correct
any!
