I would start by saying that I have no less that 4 books from the same author on various other Autodesk products. All of these previous products shipped with CD companions with the datasets for the tutorials. This particular title did not. Instructions were included in the preface for downloading the datasets from the Cengage website. However, the files cannot be found on that website at the time of this writing. I called Cengage and was transferred to Autodesk activation line, then to pre-sale customer care, hung up on, called back to Autodesk, given another Autodesk number (transfer not possible), and called that number. During the 30 minutes required for the previous "circus" I was able to locate the files, not on Cengage website but on Paul Aubin's website.
The book itself is well written and through as all of the Aubin books are but Cengage/Delmar Learning need an overhaul!
