And schematic capture is a single layer PCB with minimal widths and
thickness where  lines crossing at right angles do not connect. So we start
with a common graphics drawing program and add a schematic module or a PCB
module or a autoroute module  or a 3-D module all on a common base. I'm
surprised that no one has applied autorouting to schematic capture, That
would really be usefull.

 draughting?? Is that British for drafting?
