Which is, in fact, exactly what Inventor does -- there's a "units" node
that allows you to specify what your units are. If there isn't clear
agreement on what scale we should use (and it's sounding to me like
there isn't), we should probably just adopt that. I'd say that it is
strictly necessary to decide this before we start linking worlds, and
probably a good idea to do it ASAP (since we could be facing scale
mismatches between objects and scenes immediately).
Does anyone *object* to simply adding the Units node, lifted pretty
much wholesale from Inventor? It allows you to specify the units as:
meters, cm, mm, micrometers, microns (these *are* the same, aren't
they?), nm, angstroms, km, feet, in, points, yds, miles, and nautical
miles. This covers almost every base; presumably if we saw a crying
need for any additional units, we could later add more pretty easily
(since there clearly needs to be a general internal transformation
capability).
(See the Inventor Mentor, pg 125, for more details. It's pretty
straightforward-looking, though...)
