I am designing a couple circuits in Eagle.
I want to be able to have two separate circuits in the same project, on the same board, but put a perforation in between the two.
Not only for the cost savings of duplicating two circuits on one board, but because sometimes I need the boards separate and sometimes together.
Is there a way to add a 'perforation line' on the project so that when I get them duplicated, they can be snapped apart if necessary?
