Ground Pour

 by gaussmarkov

I am going to finish this tutorial with some notes on editing polygons. First, let’s look at how differently the polygon fill behaves when the outline completely contains the layout. Select the MOVE command and right click between the pads of C4 in the lower right-hand corner. This causes Eagle to select the bottom right-hand corner of the polygon’s outline. You can tell this because only the bottom and right sides have an altered look:

Escape from holding the corner and grab the right side of the polygon. To do this, left click above C4. The trace from C4 up to Q5 will light up. Right click and the whole right side of the polygon is highlighted.

Now left click to select that side so that you see this

and move it out to the right 100 mils so that you have this

Do another RATSNEST command and you will see no change compared to what we already had. As before, Eagle does not fill in where there are no pads or trace corners. But if you move out all four sides of the polygone, this is what you will get before the RATSNEST command

and after

    the,

    your message is too cryptic to offer a tip. there are times when “change layer bottom” does not prevent the route tool from reverting to the top layer when you are starting a new trace from an existing trace that is in the top layer. that’s all that comes to mind and that’s just eagle. you have to take your mouse up to the route tool bar and click on the layer you want.

    good luck, paul

    Thanks for the tutorial AND the libraries, this is extremely useful for noobs like me. Your detailed description of the ground pour is the best I’ve seen on the Net, thanks for taking time to do this!
