pcb - Finding air wires in Eagle


I am almost done routing a board. However, is telling me that there is still one more wire. I have looked but I just can't seem to find it. Is there a to make Eagle tell me where it is?



Answer



I can think of three options:




  • Zoom out as much as you can then use the route tool on the tiny board, this catches the air wire, then zoom in again and route it.




  • You can also disable the top and bottom layers so the air wire becomes more visible.





  • Yet another option is to run the provided "length.ulp" script (File->Run... or ULP button). This script shows a list of all the nets, on that list there is a column "Unrouted", some net is not completely routed a value should appear here instead of "--". You can then type on the command line "show net_name" to highlight it.
