  5. Acknowledgments This book is a collaborative effort involving far more people than listed on the cover. Personally, I would like to thank my family, whose patience and understanding made this, and all other pursuits, possible. Professionally, I would like to thank the coworkers, clients, customers, and friends whose input and ideas have helped build the knowledge and experience that I draw from in applying concept to practice. I would like to thank Lucas Larue for the work he performed as technical editor for this edi- tion as well as all of the help he offered me in the past as I traveled along my own road to mas- tering Autodesk Inventor. A special thank-you goes out to those who have contributed to the Mastering Inventor series in the past: Thom Tremblay, Sean Dotson, Bill Bogan, Andrew Faix, Seth Hindman, Dennis Jeffrey, Loren Jahraus, Shekar Subrahmanyam, and Bob Van der Donck, all of whom are true masters of Autodesk Inventor. Thank you to the team at Wiley: Rob Truhn, Jenni Housh, Connor O’Brien, Willem Knibbe, and Pete Gaughan, for their patience, focus, and professionalism, without which there would be no book. Your hard work and support have eased our efforts in turning ideas into pages. —Curtis Waguespack
  6. About the Author Curtis Waguespack is an Inventor Certified Expert and an Autodesk Manufacturing Implementation Certified Expert. He has served as lead author on three previous Autodesk Inventor books: Mastering Autodesk Inventor 2009, Mastering Autodesk Inventor 2010, and Mastering Autodesk Inventor 2011. He has taught Inventor in the classroom and has con- sulted with and supported manufacturing and design firms in a wide range of industries, including aerospace, consumer products, and industrial machinery.
