Changing all via in design

i need to change via size , in my design.a single click how to select all vias in kicad

In the lower right corner of the PCB editor, there is a selection filter. Set it to only select via’s:


… and then drag a selection box around your whole PCB.

Another method is to work with the net class system. All nets are always a member of a net class (If you have not worked with net classes, then all nets are a member of the “Default” net class. You can change the via properties of the net class (and create new net classes etc) in: PCB Editor / File / Board Setup / Design Rules / Net Classes, and then use: PCB Editor / Edit / Edit Track & Via Properties to update the vias.

Here’s one way, taking advantage of the selection filter.

Untick All in selection filter and then tick Vias.

Ctrl-A to select all (vias).

Right click to bring up the context menu, Properties, edit size, OK.

Note that it’s probably better to use the net class mechanism to classify tracks and hence vias, to assign sizes, than to edit their sizes directly.
