The only improvement that I know of is now when you import
dwg lines, Revit won't tell you most of those lines are useless
and off axis. Because now Revit will move those line into a
precise Revit position automatically. But I haven't found that
to be worth much. And I don't find the notion of "interoperability"
to be worth much either. You look at drawings from some
other program and you start a Revit project from them. If there
are dimensions on those other drawings, then you can start
your Revit model that much quicker.
