Check out R 2009 via The AutoCAD Resource Center

A new online educational resource is now available for AutoCAD 2009 users or would-be users - the AutoCAD Resource Center, a Web site providing an abundance of free resources and information on AutoCAD 2009.

The resource takes advantage of video clips to provide readers with useful educational and tutorial material. For example, a video on layers shows how users managed layers pre-2009 and then how to manage layers using AutoCAD 2009 products. Additional material available to users includes:
customer stories
white papers
how to articles
tips and tricks
Naturally, free trial download software is available. See more at http://resources.autodesk.com/autocad/
