Andrew,
        No insult or derogatory meaning was read into your comments. I have 
read your posts for enough years to understand that typically you don't write 
with any personal malice. Well, ahhh, possibly, just maybe towards certain CAD 
software developers?  8^o

        I just wanted to make sure that the concept of creepage was not 
obscured or dismissed completely based on your comments. It tends to go beyond 
the basic PCB design in most cases but can very easily become a compromising 
situation to the end circuit performance or safety once said PCB is put into 
enclosures/environments.

        Further, I am not knowledgeable enough to give specific instruction or 
more detailed instruction. For myself I typically appreciate somebody just 
bringing the issues to light where I can further investigate them myself and 
determine if the "car" I am looking at is a Mazda or Toyota and get it right.

Sincerely,
Brad Velander

Fair enough. So creepage isn't an IPC term, but it could just as well be. Imo, 
in this instance it's fluff and does little more than to obfuscate the 
underlying principle. Got kids? Okay, then do this, teach the 4yr old that "NO! 
It isn't a tree, it's an Oak...Got it?" or "No, Bobby, that's not a car, it's a 
Mazda". To me, that sounds like mud, or worse, like unthinking rote.
