Georg Beckmann mentioned having a little utility to convert the GERBER output from CAMTASIC to PROTEL compatible Gerber.... for import to Protel. Does anyone have this file they can make available to me? I would like to test it on some boards I am plying with. Could be very useful.... thanks Bill Brooks [EMAIL PROTECTED]

The program adds the Dnn and cuts the first 3 lines of the gerber that protel don't understand. It is a simple DOS program you can start in a dos-box with the name of the source gerber to convert. The result is a file with the same name but a gbx instead of a gbr extention. So you have to rename it and preserve your source somewhere. With this I was able to import the gerber. The drills I first imported in camtastic and had to make a tool file. ( In my sources the drill tools and the apertures are only in a text-Doc ) Then I exported the drills as a gerber and imported to protel on a mech layer. With global change it was possible to add a hole of the same size then the pad on this layer. Now I can make the post processes and even make minor changes on this pcb. --> If anybody wants the program, please let me know, it's free.
