How can I change the drill size of all pins on one specific custom footprint?
I am creating a custom footprint for an Arduino Micro to through-hole mount into my PCB design. The Arduino format is similar to a standard DIP package, except that instead of conventional IC DIP pins there are two rows of SIP headers (pin pitch and row spacing conform exactly to standard DIP packaging). So, I made a copy of a 40-pin DIP and removed the extra holes. This works fine but for one detail: IC DIP pins are much finer than the SIP header pins. The hole diameter for the DIP pins is too small to properly accommodate a SIP header pin.
How can I increase the hole diameter for all 34 pins of my custom footprint without making any global changes and without having to visit each of the 34 pins individually?
