Click on the Display icon (blue/red/green overlapping squares) to the 
left or use view/display/hide layers. Click to the far left in the line 
whose name you want to display or hide then choose OK. Refer to one of 
the tutorial links mentioned.

Click on polygon, set polygon toolbar attributes (layer, solid, isolate 
etc.) , create the polygon outline around the whole board, click on 
ratsnest. You can test this by creating a few wires and framing them 
with a polygon outline then clicking on ratsnest. It gets more involved 
when you want to **Restrict** the pour to only certain areas or connect 
to the pour. Again tutorials and archive searches are your best bet. 
Search on >"copper pour" eagle<, >polygon ratsnest< etc., but get the 
Display fundamentals out of the way first. Also, learn what each icon 
to the left stands for, its much faster than using the dropdowns.
