I am currently working on a project and I'm about to get the gerber files check by FreeDFM.com. My question is, in my gerber files there are a couple that have the extension .C1 and .C2. In FreeDFM.com they want me to specify what these are (Inner copper layers, top layers etc.), but I have no idea what they are.
Hi Roy,
Altium designer does not export gerber with .c1 and .c2. It exports gerber files as .GTL, .GTS, .GBL, .GP1 and so on unless you have changed your export setting. if you list all names then I can give another go. Do you not have any other software which you can load and check your self and then mark what these layers are !
thanks,
