Just to throw my 2p in. I use PCB wizard and I only used the auto routing once. I had 12 wire links and most of them spanned either the width or the length of the board. It seems universal that the autoroute facility is 'pants'. I did the board by hand and ended up with 4 links all 8mm long...... The PCB was a whole lot smaller and better laid out to :-D Do it by hand whatever software you use! regards Fenris --- In Homebrew_PCBs@yahoogroups.com, "sailingto" <sailingtoo@...> wrote: > > I'm sure glad to hear that I'm not the only person who doesn't like auto-routing.
