Altium layout project for Arduino Mega 2560

I'm looking for a PCB layout formatted to work in Altium Designer of the Arduino Mega 2560 (not a shield, the actual board). When I import the Eagle board files the parts don't import in a way that I can make a library from. Maybe I'm just importing it wrong.

Also, this might be the wrong forum for this. If there's a better place let me know!

Thanks!
