Yes, these negatives are years old and I have a Protel CNC drill layer but for home I use a centre punch.
No choice here as I'm out of these paticular PCB's and most manufactures are on holiday's till the 15th of Jan.
I am re doing all my PCB's with Altium Designer 6.0.
PCB manufactures do not accept Protel these days.
