I am quite new in the Eagle world and I need help.
I have made a bunch of simple prototyping PCBs of different sizes as part of a custom library and now I want to add a GND bus and a VCC bus (like in the photo below).
I have done some research and I have found this project:
in which this guy is just using the routing command for connecting the holes in the GND bus. But I still have a couple of questions: 1) Is this the best way for solving my issue? 2) It is possibile to do the routing directly in the library editor or I must do this in a new project? 3) Is there any difference between a route on the bottom layer or in the top layer for a 2 layers PCB?
Thank you for your time!
