I'd like to use my CAD tools to procure some PCB boards. Most of the houses I see that quick ship work from Gerber files. Could anyone familiar with this type of files please give me a resource to figure out what I need? I usually work in AutoCad, and do have a .dwg to .grb conversion routine. However, I am clueless when it comes to what to include for drill lists, dcode lists, and the like. TIA Ernie
