Re: gEDA-user: non-round PCB pins

[Matt Ettus <boyscout@xxxxxxxxx>]

I asked my PCB vendor and got this response --

====
What CAD do you use for design of the board? Please use mechanical layer for
layout of the mill-out if you use Protel.  Please uese .mil file if you use
Eagle. Just examples. Thanks.

How should I do this in PCB?

Thanks,
Matt
