I use Expedition PCB to build one PCB. Right now, I am going to send this board out to be fabricated. The board is charged by the area. So I want to put two or three the same boards to fit the area. I already finished one board layout. But the problem is that I am not sure if I can just defind the board area and copy and paste one board in that area. I tried to use the copy operations in the Expedition PCB. But it would not be able to let me do it. So can I do it in Expedition PCB? And how can I do it?
