Hi Richard
I suggest that you open the schematic and move the led and observe if
the nets remain attached to the pins. Doing this could show up nets that
are not connected to the pins. If that looks OK, next run a ERC check to
see if that reveals any clues. Not likely as airwires seem to be present
and so Eagle believes an airwire is justified between two points.
Next, back on the board, move the LED ( you may care to record its XY
location so you can return it to the current location later.
When the led is moved do the routed traces at the pins move with the
led? If not another question arises, did you use the ROUTE command to
add the traces which will snap to pads and airwire ends or use the WIRE
command which wont snap to airwire ends and so you can be left with tiny
airwires?
With the LED moved, run the DRC, Hope fully the airwires may be larger
now and then you will be able to get INFORMATION (net name) from them.
Then I would try to pick them up with a route command. CliCk ROUTE and
then click on the end of the airwire. Then drag out a route to somewhere
convenient so you can then learn something about the signal name of the
airwire.
I assume this is a double sided board. Check you have the layers defined
correctly in the DRC.
Questions: Is the schematic and Board consistent?

Richard,
From the board layout editor, go to Options -> Set -> Misc and set the
Catch factor to 0.
Then, start a route (Edit -> Route), and click anywhere in the layout
editor. The nearest air wire will start to route. Move the cursor
around and zoom in and out to locate the air wire.
By setting the catch factor to zero, the Route function will pick the
nearest air wire without limitations on how far that air wire is from
the click location.
Hope this helps,
- Chuck

Re: Eagle 8.5.1 Air Wire Errors
rarndt Jan 8, 2018 3:47 PM (in response to dukepro)Yes, this did correct the problem. It does make group move not work, since then grouping selects the nearest component rather than allowing you to select a group of components.

1 of 1 people found this helpfulHi Richard, This was reported on the main Autodesk EAGLE forums just before Christmas. They've identified the cause now I believe and it'll be fixed ASAP.
Hi Chuck, in EAGLE v8 (not sure the specific version it became available), you don't need that catch factor trick anymore as airwires have a section in DRC so you can find them easily by clicking on them in there.
Best Regards,

Well, THAT's an improvement. I've manufactured at least one design that
still had an air wire. I hope the didn't remove existing functionality.
I guess it's time for me to retire from the news groups into reclusion,
where the only company I have is v7.

Nope, the existing functionality is still there :-)

No!!!! Still lots of v7 and earlier users and a lot of your expertise is still very relevant for v8 issues! Definitely not anywhere near time for you to retire from here
You should give a recent freeware version of v8 a try if you haven't already. They now have Push&Shove and also integrated SPICE simulation. It's improving a lot.

Sounds nice. However, until they provide a perpetual license, and time
I spend exploring v8 is a waste. Much of the work I do is on a secured
network, and I can't be plugging machines into the Internet just so that
Eagle can phone home - whether it's once every 14 days, or once a year.
Can't do it.
I expressed to Jorge some time ago my position. Many of the new
features in v8 are very attractive to me, and I would love to explore
them. But until the licensing issue is fixed to our satisfaction, it's
pointless. Right now, I think that Autodesk will never provide this
option, which means that when the time comes that our needs dictate more
functionality than what v7 has to offer, I will have to exclude v8 from
the qualification process.
'nuf of that whiney license stuff.
As far as hanging around, I'll continue to monitor the newsgroups until
Autodesk retires them. Since they would rather steer their users to the
web with all the non-Autodesk crap that gets loaded, the NNTP servers
probably won't be around much longer.
What a bleak outlook. This sucks, doesn't it?

As a follow up, Autodesk have released a bug fix release 8.5.2 which can be found here.
This release fixes the known airwire issue and also an issue with incorrectly highlighting nets and showing them on other pages when adding to an existing net.
