I have been using EAGLE for a while now and I very comfortable with the software. Any way I have been working on automating most of the procedure of double sided PCB since manual way generate errors some time.
I am trying to generate the reference holes to mill out the pcb using milling machine, bit I can't figure a way to do that! I found that there is a ulp (mill-outline.ulp) has some options about setting zero reference and reference holes but it is not clear how to do that and I have been experimenting for a long time without finding a way!
Can someone please help with this ulp? And if anybody knows a better way of doing reference holes please guide me..
