PCB notices if you use 'move line to layer' on one segment of a trace and creates vias as needed to keep that trace connected (at least at the ends, it doesn't notice if you made a big 'x').
If you move a multi-line trace to another layer piece by piece, you end up with unnecessary vias. I see three courses of action: 1) Leave it as is, extra vias stay, user deletes if they want. 2) If you move a line to the same layer as a line it was connected to by a via (and no other features on other layers are electrically connected to the via) then the via is removed. 3) As in (2), but the via-creation code is changed to set AUTOFLAG (so the via is "created by the autorouter") and only vias that were auto- created in this was are removed (other rules same as (2)). -- Ben Jackson AD7GD <[EMAIL PROTECTED]> http://www.ben.com/ _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
