You can lay down copper polygons in the regions you don't want tracks to run (on each routable layer) before auto-routing, then remove them after auto-routing. It's a tad kludgy but fairly easy to do.
The auto-router understands all exisiting copper and will avoid it; you can hand-route half your board and auto-route the rest afterwards. harry ----- Original Message ----- From: "Bob Paddock" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, March 14, 2004 8:32 PM Subject: gEDA-user: PCB Keep-out layer? > > In Protel there is the concept of a "Keep-out Layer".
