You are right, I have assumed that the new connector will have the same dimensions as connector I used as base (I copied other library), and only changed pin order.
I was wrong, so now I will correct the dimensions and check again.
Still, can you tell me if at least the pins order is correct?
Also, how do I move element by given offset in Eagle? I mean, I want to select P1-P8 and then move in Y. I tried using Group tool to select P1-P8 and type "Move 0 5" or "Move * 0 5" but it says "unknown pad"...
