• Platform: Mac OS X 10.13.5
  • Eagle Version: 9.1.1

For some reason, when I apply my ground pour (draw polygon with name GND and hit ratsnest), the ground pour covers my other components as well as air wires in the Eagle board view.

I don't think I experienced this with other board designs.

Is there something that I'm doing wrong?

  • \$\begingroup\$ To me, it looks like you had put all components on the bottom layer instead of the top layer. Your PCB is upside down. See the BERG label on your USB connector. It's mirrored. \$\endgroup\$

    \$\begingroup\$ I think a tight clearance & low-resolution pic are making it look like the pour is connected to pads it shouldn't be and actually isn't. You can see where it is properly connected to pads by the 'reliefs'. As for the 'air wires' - they're not 'real' - there's no copper to prevent the pour from being there. I'm confused as to why you've poured the ground plane before routing anything else ... ? \$\endgroup\$

    \$\begingroup\$ The air wires are connections not routed yet. It does not make sense to isolate them from a ground pour. Do the routing first and then add a ground pour. At least route 1 or 2 air wires to see the effect on ground pour. Ground pour requires to set the isolation distance before. \$\endgroup\$

It's a known, reported bug, first seen over here.

Until a fix is issued in a future update, the only work around by now is running this command in the command line of Eagle:

set Option.LayerSequence 23 1 16

Ensure that the shape for the ground pour was named GND Then hit the ratsnets command.

  • \$\begingroup\$ @AllenHoung what setting do you have for isolate? If it 0, as shown in the screenshot above, then of course it will cover everything. Isolate is the clearance between the plane and any other traces/pads/planes. \$\endgroup\$ Commented Jul 18, 2018 at 10:17
  • \$\begingroup\$ @ConcernedCitizen, you might want to use sensible settings in your screenshots. \$\endgroup\$ Commented Jul 18, 2018 at 10:17
  • \$\begingroup\$ @TomCarpenter such as? Having isolate as 0 gives me no issues when i hit ratsnets. It will default to your DRC settings... \$\endgroup\$ Commented Jul 19, 2018 at 11:07
  • \$\begingroup\$ @TomCarpenter what's your value for isolate? \$\endgroup\$ Commented Jul 19, 2018 at 12:47

So after trying routing, it seems like this is a new feature in the latest eagle? It seems that eagle will only highlight the specific airwire that you are trying to route as shown in the screenshot below:
