I found these explanations, but am am missing something...
I have a board will all vias=.045 drill=.028 and I want to chage to
vias=.040 drill=.024.
With the explanations bellow, I can change the drill size easely, but
the via diameter does not change :(
I also tried edoting the file, but it is not self explanatory to me, I
changed the line
ViaSize 400
but it has no effect.
Another question, How do I display the keep-out zone for vias?
Please help,
Alain
