Thanks for the suggestion. Unfortunately manually editing the file for
boards that I am working on is not a good option. I don't just generate
a file once and check it and be done. I run back and forth between the
layout program and the Gerber viewer many times when I am trying to work
on a problem. Having to hand edit any of the output makes it rather
pointless.
I can't find anything that would be a true standard for drill files. I
guess the closest thing is the page at excellon.com, but it seems
standard practices are not in compliance with their page. When I tried
using Viewmate to look at these files the drill file was interpreted
like a Gerber file and used 3.4 format! From the Excellon web page the
format is always 2.4. But I was able to override that. The problem
with Gerbv is that there is no way to manually set the tool values as
they would do at the fab house I believe.

So is there any chance of getting some feedback on my issue

Hello Rick,<br>

It looks like the Gerbv does not understand the tool definitions

If you manually edit the header of the file to something like this
it will probably work. I do not remember right now what G90 is
for. Also, You might want to split the non-plated holes to
another file.<br>
