Copper pours in plane layers

Element 14 User wrote on Mon, 21 February 2011 15:45

I would like to create a copper pour area on a plane layer.  That

is,  I would like to place a polygon on a playe layer and fill it with

copper, and not anti-copper.  I want the polygon to be automatically

isolated from the surrounding plane copper.

 

I have not figured out how to do this.   Any tips?

I don't think you can do this with plane layers.  However, you can do this

with normal layers using polygons.  Use a large polygon instead of making a

special plane layer.

Yes, I know I cannot do this.  I would like to suggest that eagle consider this.  There are a number of tools (e.g. Or-Cad, Express-PCB) that do perform this function.  It is especially useful for placing core voltage planes under BGA's or separating analog voltages from digital.

I assume that by "plane layers" you mean EAGLE's "supply layers"

(i.e. layers that have a name that starts with a '$' character).

Please note that the next version of EAGLE will no longer support

supply layers. Existing boards with supply layers will automatically

get those replaced with an appropriate polygon in that layer.

With signal polygons you have much more flexibility than with supply

layers. You can have more than one power plane on the same layer,

or route wires within the polygon.
