I've been trying to edit the spacing/position of the pads on this example .brd file-
http://www.instructables.com/files/orig/FG0/FRGD/I4PHX5J0/FG0FRGDI4PHX5J0.brd
And though I have accidentally modified the traces plenty of times, I have no way to modify the pads in the center.
So my question is- how can I edit, and more specifically, redimension and move already existing pads in a board file?
