For 2011 we've decided to release a quick update to our Guide to BIM e-book. After thousands of downloads it was time to give it a slight tweak and fix a few typos. We've also added a new "social" aspect to it, allowing you to more easily share it with your friends and colleagues who are wanting to learn about Building Information Modeling.
Thanks to everybody who sent in feedback, it was a great help and we are glad you found it useful!
