Hi, Mark. According to
http://support.microsoft.com/?kbid=282547 :
AutoCAD Format 2-D (*.dxf) filters are only included with Office 2000 Premium; you must install Microsoft PhotoDraw 2000 (located on CD-ROM 3) to obtain these filters. You can also obtain them in one of the following ways:
* Install Microsoft PowerPoint 2000 or Microsoft Office 2000 over PowerPoint 97 or Microsoft Office 97. PowerPoint 97 and Microsoft Office 97 already have the filters installed.
* Install the filters by using the Office Converter Pack (in the Microsoft Office 2000 Resource Kit or Office XP Resource Kit).
* Install the filters by using the stand-alone version of Microsoft PhotoDraw 2000.
