That does not do it. From 2008 I can save as a previous version but it won't let me export. I get this message at the command line
"Command: _AecExportToAutoCAD2000Dxf
Command not allowed because drawing contains objects from a newer version of
this application."
This is the opening text from the command line;
"Opening an AutoCAD 2004/LT 2004 format file.
Regenerating model.
AutoCAD Express Tools Copyright © 2002-2004 Autodesk, Inc.

Autodesk DWG. This file is a TrustedDWG last saved by an Autodesk application
or Autodesk licensed application."
I am trying to export to 2000 format but in order to do that I have to open it in 2010.
