No. Unfortunately AutoCAD only understands black and white as both black
(15,999,999 colors) Revit on the other hand understand black as black and
white as white.
The only thing you can do is set the fill to a separate layer and then turn
that layer off in AutoCAD. Some Revit users have employed a method of using
255,255,254 with is 1 byte away from white. This can be used to fool AutoCAD
into seeing a very light color, but it is a sad work around in AutoCAD.
Maybe someday AutoCAD will understand black and white, but I think it will
be another 10 years.
