Viewing, Editing, and Saving AutoCAD Files in Microsoft Office Visio 2003

Office Developer Center: Viewing, Editing, and Saving AutoCAD Files in Microsoft Office Visio

"Use add-ons included with Microsoft Office Visio 2003 to automate importing Autodesk AutoCAD files into Visio drawings, either as view-only (read-only) objects or as editable Visio shapes. You can also use add-ons to automate importing AutoCAD block libraries and even save Visio drawings in AutoCAD file formats (.dwg and .dxf). "

Something for me to think about the next time AutoCAD comes up...
