If you make pads that are 80 mill square, then two pads of an IC have
a 20 mill seperation, or one pass on each pad for isolation milling.
Set your line widths to 80 mill and then all your connectors are
square and require only one pass as well.
WinQCAD allows you to set your line widths as you like, then in
handRoute, select manually change line widhts. then just a single
mouse click on each line segment (lots of clicking) and you can run
across the board changing line widths as needed.
Another way might be more automated.
If you can isolation route your board on one layer, then select that
laywer and isolation route that and just keep going until your lines
are where you want.
Of course this means you have to select lines from different layers.
sorry, don't know an automated way.
