Thanks to Steve & Brian who replied to my question; I have checked the points they raised, and still no luck.
However, I noticed today that when I start the Autorouter, there is quite a bit of copper already on the PCB, from previous sessions. Maybe I'm doing something completely wrong, but my process is: 1/ Place components as ideally as possible 2/ Autoroute. DRC reports clearance errors and short circuits 3/ Tools, "Unroute All" (but about 15 tracks remain) 4/ Adjust component placement 5/ Autoroute. DRC reports clearance errors and short circuits again It looks as though the Autorouter is unable to work around all the existing copper - is there something else to do to 'purge' the board of copper, in addition to 'Unroute All' Thanks, Peter Moreton * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[EMAIL PROTECTED] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
