Hi folks,

Two related questions:

First:
After laying out my board in pcb, I added a copper pour for a top-side ground plane.  I see that the ground pour does not leave clearances around my 0805 pads.  I then noticed that the 0805 footprint that I was using has zero clearance.

e.g. one of the pad definitions is:
 Pad[-4000 500 -4000 -500 4000 0 5600 "1" "1" "square"]

I have edited the footprint file to introduce a pad clearance (I just changed the 0 to 10mil), but how do I then propagate that change into my layout, without laying out the board again?

I tried re-running gsch2pcb then re-doing the copper polygon, but that did not introduce a clearance around the 0805 pads in the layout.

Second:
Also, I apparently laid down some traces (lines) without the "New lines, arcs clear polygons" option checked, so some of my lines have clearances for the copper pour, but others do not.  Can you recommend a way to efficiently add clearance for a set of lines?

Thank you,
James
