Drawing Ground or Supply polygons on Eagle Cadsoft

This entry is to log the steps on drawing ground or supply polygons with Eagle Cadsoft

Figure 1. Ground polygon end result

Step 1: Prepare Board 

Step 1. Route all pads accordingly

Step 2: Draw polygon area

Step 2(a). Select Polygon Icon

Step 2(b). Enclose PCB frame with polygon area ( dotted line )

Step 3: Check Polygon to see if in correct layer

Step 3(a). Select the 'info' icon

Step 4. Rename Polygon to GND or Vs

Step 4(a). Select 'name' icon

Step 4(b). Something like this should appear

Step 4(c). Change name to 'GND'

Step 5. Generate Ground/Supply Polygon

Step 5(a). Select 'Ratsnest' Icon to generate polygon

Step 5(b). Polygon generated

Step 6. Isolate route and track from polygon plane
Initial Isolation : 0inch. Plane very close to route and pad

Step 6(a). Select 'info' icon again

Step 6(b). Click on the drop-down menu on 'Isolate'. Select a suitable value

Isolate at 0.016inch:
