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.

I see where you’re coming from, but I’m not sure I’m ready to agree yet.  In technical, code terms, yes, but conceptually a schematic is a lot more abstract.

Sorry, yes.  Probably a bit outmoded now though… :)
