Eagle 8.5.1 Air Wire Errors

Question

With Eagle 8.5.1 I have air wire errors that I can not figure out how to correct (see attached). I am modifying a PWB created in previous Eagle version, by adding one tri-color LED. Both pins 1 (Din) and 2 (VCC) of the LED show air wires, and it is so small that I can't zoom in to see it. Pin 3 (GND) routes fine to the GND polygon. I have tried re-routing these two lines many times, with exact same results. This LED is the only thing I have added to this board using Eagle 8.5.1. Guidance please.

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

Hi 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, Rachael

Hi Chuck, dukepro wrote: Well, THAT's an improvement. I've manufactured at least one design that still had an air wire. I hope they didn't remove existing functionality. Nope, the existing functionality is still there :-) dukepro wrote: I guess it's time for me to retire from the news groups into reclusion, where the only company I have is v7. 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. Best Regards, Rachael
