I have some files generated in Eagle: psu.brd and eagle.epf. can i import these fileS with Camtiastic or viewmate to generate Gerber file as well as makE some changes?
Generate the gerber files in Eagle using the CAM Processor. Then these files can be imported and edited by your favorite gerber viewer. But why do you want to modify the layout in the gerber editor? Just do the changes in Eagle before.
