To my friend and colleague David Fawcett, who is retiring soon: fair winds and following seas...


Many talented and hardworking people gave their best effort to produce Mastering AutoCAD 2018 and AutoCAD LT 2018. I offer my sincerest gratitude to those individuals who helped bring this book to you.

Heartfelt thanks go out to the editorial and production teams at Sybex for their efforts. Mary Beth Wakefield managed the project and helped us make all the right connections. Jody Lefevere made sure things got off to a great start and provided support from beginning to end. Gary Schwartz skillfully managed the development process. Richard Hawley did an excellent technical editing job and offered many great suggestions. On the production side, Rebecca Anderson kept the production end of things running smoothly, and Judy Flynn made sure that I wasn’t trying out new uses of the English language.

Thanks also go to Denis Cadu, who has always given his support to our efforts over many projects. Jim Quanci always gives his generous and thoughtful assistance to us author types. Thanks to Elinor Actipis for providing help with general Autodesk matters. Finally, thanks go to Alison Keller, Daniel Kuhman, and KB Lee of the AutoCAD Customer Counsel and the AutoCAD 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.
