I was interested in this book because it seemed less like a "how to" book and more about what makes this technology work. It has not disappointed on those issues at all. Very rich in information. The biggest weakness I have found is that the author clearly favors certain software packages over others, which I can understand... everyone has their preferences. However, when discussing Autodesk's Revit platform, I found the book to be overly biased and sometimes, flatly, mistaken. This issue does not however, severely detract from the overall value of the information. Where the book seeks to discuss BIM without focusing on specific software, it is without equal. As long as you aren't making purchasing decisions based on the information, anyone familiar with the basics of BIM will find it fascinating.
