DirtyPCBs support / EAGLE: Add a GND bus and a VCC bus to a proto board
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.
I have done some research and I have found a project in which this guy is just using the routing command for connecting the holes in the GND bus. Unfortunately, as new user i cannot add links to the image and the project that I've found, but this is the title: "Files for making your own Arduino Protoshield " in Arduino Playground.
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!
