Eagle Tips: Default Via Size

In Eagle, vias are square and overly large by default but you can change the default. All you have to do is create/edit eagle.scr in the scr directory of your Eagle installation. Enter the following lines:


change diameter auto;
change drill 13mil;
change shape round;

I chose 13mil as this is the minimum drill size supported by OSHPark but pick whatever value suits you best, of course.

Problem: default Eagle via is big, square, and ugly.
