Ahh, ok... The iProperty add-in (by Patrick D.) can actually do this for
you. The bummer part, tho, is that they only update on a Part Save, unlike
parameters, which update dynamically (any time there's a change in the
part). So, if you save the top level of an assembly and all its sheet metal
children, none of the flat pattern extents will be updated. You have to
either do a Save All (and grab a beer while you wait 10 min for it to
finish) or open each part individually and Save. With Parameters (for
example an adaptive Length parameter), on the other hand, I can change my
model (which, for example, changes the Length of the part), and the Length
will be dynamically updated across the board. Saving the top-level assembly
w/ subcomponents will update the Length of all parts. It'd be nice to have
this usability with sheet metal extents. Unfortunately, I don't really know
if that's feasible without ADesk incorporating sheet extents into their
parameters.

Actually in re-reading this I am mistaken. The tool I'm talking about will
allow you to access the extents & put them in your title block for instance,
but won't let you use them in the parameters table for equations (I don't
think). No, it's not mine.
