Hi,

I have a board with lots of ground vias and I need to increase the size
of all of them.
Is there a way to change all at once or do I need to select every
single one of them?

Thanks, Tom

Hello,

Select a via with the pop-up menu and then Via Drill.
There is a global via change option.

Pedro.

When vias are created, they are created with the "default" drill size or
the current "alternate" drill size.

The default drill size is recorded in each individual via as a magical
value of -1.

The current alternate drill size is whatever the current mil or mm
setting is for the "Alternate Drill" size in the Dimensions | Tracks and
Vias dialog. That value is used in place of the -1 in each such via.

The interpretation of any AND ALL vias subject to the "default" via
drill size can be instantaneously changed merely by changing the default
drill size in the same dialog. You do not need to visit each default
drill sized via.

Only vias which have an alternate drill size setting need to be
revisited individually. And of course, as always, you can edit these
Kicad files with a text editor, but the format is not self evident so
always keep a backup before you begin experimenting with a text editor.
The file formats are documented elsewhere however.

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
