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.

Rick
