Elgin,
You might have had a small conversion error there. While I tend to design in English units, many CAD programs default to metric on export. Catia has a real issue with this. So I always tell the technician how big I expect things to be when I send the file. It's always amusing when something you send in inches comes out in millimeters, or meters.
Fortunately, scaling is easy to do, if you know what the problem is. On the other hand, the book author could have just proven the value of rapid prototyping in an unforgettable, though unintended fashion.
