Team 1512,
You can find all of the parts for FRC 2012 for Autodesk Inventor Professional at
http://students.autodesk.com/?nd=kitofparts_view
There are also parts from 2011 and 2010 formats in the parts library.
I know that you are working with AutoCAD right now but please remember that you can get Autodesk Inventor Professional 2010, 2011 or 2012 free as a FIRST team member.
We are also offering free Inventor training materials for all these versions through our partner, 4DLearning which may help get you moving on the new user interface.

Hopefully this will help you and your team moving forward.
