just 2 questions:
1. How is it possible to modify the layout perimeter or the borders of a PCB? I have to make a PCB with a strange shape, absolutely not rectangular.
2. In a manufacturer's data sheet, there is a suggestion of how to make the layout of the PCB. I could import it as a jpg file, as the attached one. May I, in your opinion, use it to speed up the layout in Eagle or not? And, if yes, how?
Thank you very much in advance if somebody could help.
