I've used that method before; it's a bit ugly, but it works - for very simple boards, anyway. The way I do it is I print out the layout using my good ol' Inkjet, tightly tape the sheet of paper to the board, and drill the holes first. Once all the holes are in place, I meticulously draw all lines as they appear on the paper, using a set square to measure the lengths and angles. Stone-age technology, I know. I really should get a laser printer, but I'm a bit shy on lolly - and space near my 'puter, for that matter. The 2-layer boards using through-hole wire jumpers sound promising. I'll start redesigning for 2-layer boards, then. :) _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
