The New Hotness

Had to look this up again…

Problem: I needed a shielding plane under a sensitive gizmo that was separated from the ground plane covering the rest of the board. EAGLE poured the ground plane atop the smaller shield polygon, despite the two signals having different names.

Solution: set the ground plane’s Rank to 2, which means it’s less “important” than the smaller plane. Thus, the smaller plane gets drawn first and the ground plane surrounds it.

A good ground-plane tutorial is there.

[Update: That’s a new link location, per the comment below.]

Memo to Self: The default Rank is, of course, 1 for all polygons.
