How can I change all drill holes on my PCB to 0.8 mm?
I want to use isolation milling and want only one drill bit besides the graver bit. I would like to drill the few larger holes by hand bigger afterwards. How do I change all drillings e.g. to 0.8 mm?

Please press the [Ctrl] + [a] key in the layout to
select all. Then type [e] for edit. Now the big change dialog opens. Select the solder pads and the vias on the left and click the [ Ok ] button. Now the dialog for solder pads and the dialog for vias appear one after the other. There you set the drill hole to 0.8 mm and click [ Ok ].

If you also have SMD components, this method will unfortunately also create drill holes for them, which is certainly not desired. The selection assistant must then be used instead of [Ctrl] + [a]. The selection assistant can be found in the Edit menu:

With [Start]
all solder pads with a drill hole are selected and the vias.

When you close the
assistant, immediately press [e] for edit as described above.
