What size are the pads? I will try to do it in Eagle (I do not know it
can import .pcb). I think there is no need to do it as an octogonal,
as other user suggested, there is a simpler way, you can copy the
figure and rotate it 45º, so you have an orthogonal (the original) and
a diagonal one (the one you rotated 45º). Then you can check
differences between both.
