That hardly applies.  Architecture, and art, are not engineering, and
require no basic understanding of mechanics.

You also conveniently diverged, and avoided answering my question.

I do not feel you are one of these such people.  Though there are people
that do have innate understanding of some things, that doesn't mean an
education doesn't give you certain qualifications, understandings and
abilities.  Most people who put education down, don't usually have one...and
of course, that makes sense.

Ah, but I do understand that completely.  I also know enough in this field
to know when someone doesn't understand what it is they are talking about.

I do believe that you don't understand some of the things we have talked
about.  I believe you have a "working knowledge" but not an understanding.

If designed properly, that mechanism can easily last a lifetime.  Also, wear
does not imply imprecision.

That could very well be, but if designed properly, that need not be.  The
"unmentionable" scanner IS a three pass scanner, and has NO registration
problems between scans.
