I noticed that e-Learning for AutoCAD 2007 now is available. It's free for subscription customers. Not so much about the new stuff though. It's more of an update of the previous lessons. But for some users it can be a great start to get familiar with the the features below.
- Customizing Toolbars and the Keyboard (learn to use CUI)
- Working with Blocks (Dynamic Blocks)
- Working with Tool Palettes
- Working with Sheet Sets
