A PS to this thread which may actually be a question ...

Just today I had occasion to read a .dxf file into Mathematica, looking for
a way to display it (a template for a kitchen sink from Kohler, if you must
know :-).

I received an error that there was no Z-dimension.  This should not have
surprised me, as on-line help indicated that the result of Import-ing the
file would be a 3DGraphicObject.

Still, it seemed to be a bit odd that Mathematica gave up so easily on a
simple 2D figure (rectangle with rounded corners).  Is there perhaps some
simple rationale for this?

I also noticed that a lot of graphic conversion programs are dropping .dxf
(and I assume also .dwg/f) formats from their inventory.
