Still no real drawing file compatibility breakthroughs between CAD
programs however. That remains to be done somehow.

I beg to differ.   IGES is a good exchange format that very many
CAD packages can write and read.  I was the chairman of the
FEA subcommittee years ago and it really does work IF- IF - IF
the CAD software suppliers desire to exchange data.  In some cases
they INTEND to keep you captive and prevent  exchange
of data.  Some produce a lame IGES converter ("in" usually works
well, "out" is more likely to be lame) to try to keep the customers.
IGES is only a standard format and has NOTHING to do with
the myriad of individual implimentations of the converters to and
from the IGES format.   (Initial Graphics Exchange Standard)
