Many talented and hardworking folks gave their best effort to produce Mastering AutoCAD 2013
and AutoCAD LT 2013. I offer my sincerest gratitude to those people who helped bring this book
Heartfelt thanks go to the editorial and production teams at Sybex for their efforts. Willem
Knibbe, as always, made sure things got off to a great start and was always there for support.
Jim Compton kept a watchful eye on the progress of the book. Melanie Perry did an excellent job
of ensuring that I didn’t make any glaring mistakes and offered suggestions based on her own
writing experience. On the production side, Dassi Zeidel kept the work ow going and answered
my dumb questions during the review process, and Judy Flynn made sure I wasn’t 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
types—I’d be lost without your help, Jim. Thanks to Barbara Vezos and Richard Lane for their
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.
