So I am working on a physically sizable project, and want to use large PCBs as such. What I have in mind is 8 in by 8 in PCBs or maybe even larger. However, I do not know what software to use to do this. It would be very ideal if I could use Eagle, but, I don't have over a thousand dollars to throw away. What would you guys recommend I do? And for that matter, why is Eagle so damn limited as far as PCB size goes?
