I sent it to Abdulrahman Lomax he wanted to bring it to the file section in
this forum.
But anyway, I send it to your e-mail address.

Betreff: [PEDA] CAMTASTIC GERBER TO PROTEL TRANSLATOR?


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

Hi Georg, Could I get a copy of the Gerber translator program you mentioned
in this post?

Subject: [PEDA] AW: imported Gerber info missing


Thanks for the advice, someone made me a simple program to convert the
gerber files generated by camtastic that protel can inport it.
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.


Georg
