Despite the author's own wonderful review of the book, and every book that she has written to date, "very interesting" I was very disappointed. Look at the cover; it should let you understand the lack of her industry engineering and manufacturing experience. Can you address the features another ways besides designing parts that people will not make? Overall, I found this book a waste of my time and money. But my company paid for the book. I am not too mad. I will not even use the book as a reference book.
