Set the check boxes Diameter, and the via/pad diameter will be taken
into consideration for the inner layers. This can be of interest if a pre-
defined pad or via diameter exceeds the calculated value. Otherwise the
pad or via in the inner layers would be smaller than in the outer layers. If
you want pads/vias to have the same diameter in all layers, set the option
Diameter.
The option is set off, by default, for new created boards, but will be set
on for boards that are updated from version 3.5 or prior because in these
versions pads and vias had the same diameter in all layers. Thus the up
