Earlier in the month the Inventor team provided me with an update of the 2D to 3D tool. I placed it on the Autodesk Labs site for download.
This latest update adds support for Autodesk Inventor 2012 and Autodesk Inventor LT 2012. This technology preview has been around a while but it's never to late to share your success or failure stories using it. You can contact us at firstname.lastname@example.org.
Getting all 3D up in here is alive in the lab.
