After I used the autorouter on my design I was left with a couple of unrouted airwires which I had to route manually and that was okay. My problem started when I found a broken connection without any airwire (see the bottom of the picture). I might have deleted it without purpose. Since the airwire was gone I wasn't able to make a connection with the router. Will the wire tool work for routing? Or is it a way of routing where there is no airwires?
