Having generated my Gerber File, I found two drilling files in the directory: NPTH.DRL and PTH.DRL . For my purposes I need only **one** simple.TXT drilling file.How could I convert or merge the two files into one TXT.file? A second question: I also need a .GML Gerber file. Is this the same as the generated .GKO file? If yes, could I just rename the file from .GKO into .GML ? Thanks in advance for your answers!
