I am using a library file provided by phillips for lumiled's rebel LED, the
fr4 version with 36 thermal vias. All the vias are very close to each other
and surrounds each LED. I followed all the directions by placing a polygon
around the vias and naming them TH but none of that works, when I use
rastnet command to pour copper all over them, eagle attempted to make copper
traces to each one, when it should be copper pour all over them. I can
supply schematic and brd file for anyone who'd be kind enough to help me
with this issue.
