Huh, that's interesting. It looks like they got sick and tired of IGES
(which people have been complaining about for years anyway). I don't
think that DWG is any better, though, except for being more popular. Does
DWG have any of the manufacturing info that PDES/STEP was supposed to
have? That was *supposed* to be the logical successor to IGES, in my
understanding. Don't get me wrong, it may just turn out to be better than
IGES depending on how the "standard" is implemented and whether or not
everyone accepts it. I agree that there is a lot of legacy data out there
to back up the move. It just looks like a step sideways instead of a step

BTW, I wonder what Autodesk thinks about this...

just my 2 cents worth,
