More a note to myself, but you may find this useful, too.
Eagle design rules and cam job files
Next, unzip/runrar and move to eagle:
$ mv SeeedStudio_2layer_DRU_no_angle_20140221.dru SeeedStudio_4layer_DRU_no_angle_20140221.dru \ /Applications/EAGLE-6.5.0/dru
$ mv Seeed_Gerber_Generater_2-layer.cam \ /Applications/EAGLE-6.5.0/cam
Run Eagle design rule check
open File / CAM Processor …
open File / Open / Job …
BTW, Seeed Studio’s Fusion PCB Service is pretty awesome. I once submitted gerber files where it wasn’t clear whether to do slots or drill holes for a 2.1mm power jack. I was promptly contacted and asked how it should be done. This is service I did not expect at this price. Thank you Seeed Studio!
