The next Inventor (2008) will work directly with DWG file format in its drawing views functionality. So you'll be able to save your Inventor drawing views either to IDW or to DWG. DWG-type drawing views will be full-featured files which even survive round trip through possible editing sessions in plain AutoCAD. Well, this will definitely make sharing of Inventor-generated drawings easier in mixed CAD teams. Autodesk calls this feature DWG TrueConnect and this "True" prefix implies that there may be problems with any round-trips of these DWG files going through non-Autodesk CAD applications.
With Inventor being more AutoCAD-like and with the high popularity of AutoCAD LT, Autodesk may consider making a cheaper LT version of Inventor, with limited "light" functions, for greenhorn 3D-cadders...
