Homebrew PCBs

Keep in mind that 45 degree traces often are not the worst case to create.

Yes, 0, 90 & 45 degrees are the typical one in layout but often the worst
case are at a slight angle.  See the sample targets:

So rotating DJ’s targets just a few degrees might be a more difficult
target.

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.
