Revit :: Curves And Precision Settings

I'm trying to find a setting in Revit that will increase the precision on how Revit draws curves.  For instance, With circles and arcs drawn in revit, you can zoom way in and will see it faceted instead of a smooth curve.  When you export the file into autocad, it puts vertices at the same spots as was shown on the screen in Revit.  Is there a setting in Revit to increase the number of vertices so when I export the file into autocad, at least the number of vertices increases and the curves look more curvy and not so segmented?  Basically I have a user who drew signage artwork in Revit, and we need it in Illustrator. There's not enough time to redraw it all in illustrator, so we know it will be segmented no matter what, but wanted to know if Revit has a setting that will increase the number of vertices hence making it less segmented visually.  I recall theres a setting for this in AutoCAD, just don't know about Revit.
