Apparently this has been around for a long time, but I just found it yesterday. I think most of the tools here are very recent.

Autodesk Impression looks interesting for AutoCAD users.
Project Freewheel makes DWF files viewable for anyone without the DWF viewer. If you want to make a rotate-able model of your robot available on your team's Inventor page, you can paste a piece of HTML code into the page that loads an embedded viewer from the Autodesk server and displays your DWF file.
A Feature Recognition tool makes it possible to get generic STEP or IGES files from suppliers' websites and easily modify them in Inventor as if they were originally Inventor files.
