Turn your EAGLE schematic into a PCB

Step 14 Add V+ Polygon

Now we'll repeat the process for the positive voltage. However, we never named that signal when we drew the schematic, so it will have some random name like "N$23"; We can use the "INFO" command to find the signal name to use when we draw the polygon, after which it's the same as drawing the GND polygon.

In this case, the V+ signal is named n$1, so we type "poly n$1"
