be aware that there are various combinations of # of significant
digits and leading/trailing zero suppression which can be generated by
various programs that don't strictly conform to the specified subset
in the excellon documentation. Also some programs, and I think pads
may be one, has options that let you use a different origin for the
drill file. I call it the "please increase the risk of a bad board"
option ;)
With gerbv, you can turn off autodetection of drill formats and
manually specify what the format is as well as an offset. By playing
with those settings you'll probably be able to clearly see when you
have them set right.
