To the memory of my brother Masayuki Omura: 19392014.G.O.

Many talented and hardworking folks gave their best effort to produce Mastering AutoCAD 2015 and AutoCAD LT 2015. I offer my sincerest gratitude to those people who helped bring this book to you.

Heartfelt thanks go to the editorial and production teams at Sybex for their efforts. Willem Knibbe and Pete Gaughan made sure things got off to a great start and were there for support at all times. Steph Barton kept a watchful eye on the progress of the book. Richard Hawley did an excellent job of ensuring that I didnt make any glaring mistakes and offered many great suggestions. On the production side, Dassi Zeidel kept the workflow going and answered my dumb questions during the review process, and Liz Welch made sure I wasnt trying out new uses of the English language.

Thanks also go to Denis Cadu, who has always given his steadfast support to my efforts over many projects. Jim Quanci always gives his generous and thoughtful assistance to us author typesId be lost without your help, Jim. Thanks to Barbara Vezos for her support. Finally, as always, a big thanks to Shaan Hurley, Lisa Crounse, and the Autodesk beta team for generously allowing us to have a look at the prerelease software.

And a great big thank-you to my family and friends, who have been there for me through thick and thin.
