I am almost done routing a board. However, Eagle 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 way to make Eagle tell me where it is?
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.
There is an ULP called zoom-unrouted. When you run it, it will automatically zoom your view to the first airwire it finds. Very useful. Here is the link:
I think that the fastest option is to select the Edit->Route and click with the left button of the mouse on the board. Automatically eagle will draw a track to the nearest untracked wire of the board (or to the latest unrouted wire, do not worry).
Some time ago I disabled all the layers except the "Unrouted" to look for the unrouted tracks, since I discover this simple and faster method.
Sorry to revive this ancient topic, but, I found a way optimal solution, available on eagle 7.6 at least.
Options -> Assign... and create two shortcuts for the enabling the default view and another to enable the airwire view, as follows:
Airwires' Assigned command:
DISPLAY NONE; DISPLAY 19;
Default view's Assigned command:
DISPLAY NONE; DISPLAY 1 16 17 18 19 20 21 22 23 24 25 45 51;
Mileage may vary, as layer may (do they?) change through versions, so, it is always a good option to go to
Layer settings and double check layer numbering.
Here, I have assigned on F11 to airwires and F12 to default. But these are just suggestions :)
