The code does not predate Express Tools which were free with AutoCAD 2000. Here's a link to a Cadalyst article by Lynn Allen: http://tinyurl.com/p2zgj The code is dated a year after that article.
You could very well be correct (I can't view tiny urls from here -- the IT dep't thinks unspeakable evil will occur apparently). Fact is I historically don't use or recommend Bonus / Express tools to other programmers so admit I'm not up to speed on what they contain. Nonetheless, like the other author, I would tend to write my own version and yes, because I'm protecting my job. Not in the way that you suggest, but from a reliability perspective. I need to be able to ensure a solution is available to any CADD station. Fact is over the last decade Autodesk has been completely inconsistant with the Bonus / Express tools grab bag to the point you can not (legally) count on it being on a candidate CADD station.
Regarding "this kind of attitude...", what are you saying? That I should only post comments which are polite and politically correct? Otherwise expect to be admonished?

In short yes, err on the side of kindness. If you want to minimize or belittle the efforts of others ala Godzillo please post to that other news server, otherwise post here as if you are speaking to friends face to face -- even if they are not here. While it is a high bar, one that I have publically struggled with myself, it is a goal worth aspiring to lest this great place degrade to the kind of chilly rooms found elsewhere.
