John,
Several ways to get to the information so I will share them all.
www.autodesk.com/first, select the 2012 Award tab and click on the link for the "Digitial STEAM site". There you will find a link "Go To Project Packet", click and then locate the "3D Files" on the top of the page under the little red tab.
You could also join the Autodesk Education Resources - FRC 2012 facebook group at
http://www.facebook.com/groups/autodesk.first/ where you can get help, support, ideas and much more. Request membership here:
autodesk.first@groups.facebook.com
Hopefully this is helpful!
Good Luck,
Kim Campbell-Djuric
