Steven – you should move your question over to the other Autodesk forum [GO
ACAD] — that's where the AutoCAD stuff happens. This one [GO ASOFT] is about
Autodesk's multimedia and scientific programs.
What you are looking for is a plot spooler. One that comes to mind is Plump
from SSC. The owner of SSC, David Cohn, is a regular on the other forum; you
can find our more about his program and other spoolers over there.
