Acknowledgments
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.

Introduction
Welcome to Mastering AutoCAD 2018 and AutoCAD LT 2018. As many readers
have already discovered, this book is a unique blend of tutorial and reference,
which includes everything that you need to get started and stay ahead with
Autodesk® AutoCAD® software. With this edition, you get coverage of the latest
features of both AutoCAD 2018 and AutoCAD LT® 2018 software along with
detailed information on existing features.

How to Use This Book
Rather than just showing you how each command works, this book shows you
AutoCAD 2018 in the context of a meaningful activity. You’ll learn how to use
commands while working on an actual project and progressing toward a goal.
This book also provides a foundation on which you can build your own methods
for using AutoCAD and become an AutoCAD expert. For this reason, we
haven’t covered every single command or every permutation of a command
response. You should think of this book as a way to get a detailed look at
AutoCAD as it’s used on a real project. As you follow the exercises, we also
encourage you to explore AutoCAD on your own, applying the techniques that
you learn to your own work.
Both experienced and beginning AutoCAD users will find this book useful. If
you aren’t an experienced user, the way to get the most out of this book is to
approach it as a tutorial—chapter by chapter—at least for the first two parts of
the book. You’ll find that each chapter builds on the skills and information that
you learned in the previous one. To help you navigate, the exercises are shown
in numbered steps. To address the needs of all readers worldwide, the exercises
provide both Imperial (feet/inches) and metric measurements. Some exercises
use generic units of measurement, and if the focus of the exercise is not
dependent on the measurement system, Imperial is used.
After you’ve mastered the material in Part 1 and Part 2, you can follow your
interests and explore other parts of the book in whatever order you choose. Part
3 takes you to a more advanced skill level. There you’ll learn more about storing
and sharing drawing data and how to create more complex drawings. If you’re
interested in 3D, check out Part 4. If you want to start customizing right away,
go to Part 5. You can check out Chapter 25 at any time because it gives you
general information about sharing AutoCAD files with your co-workers and
consultants. You can also use this book as a ready reference for your day-to-day
problems and questions about commands. “The Bottom Line” section at the end
of each chapter will help you review and look at different ways to apply the
information that you’ve learned. Experienced users will also find this book a
handy reference tool.
Finally, you can learn more about AutoCAD through the author-supplied bonus
chapters found at www.omura.com/chapters. For example, if you run into
problems using AutoCAD, see the section “When Things Go Wrong” in Bonus
Chapter 3, “Hardware and Software Tips.” To delve into the details of printers
and plotting, check out Bonus Chapter 5, “Understanding Plot Styles.”

AutoCAD and AutoCAD LT 2018
Autodesk has released AutoCAD 2018 and AutoCAD LT 2018 simultaneously.
Not surprisingly, they’re nearly identical in the way they look and work. You
can share files between the two programs with complete confidence that you
won’t lose data or corrupt files. The main differences are that AutoCAD LT
doesn’t support all of the 3D functions of AutoCAD 2018, nor does it support
the customization tools of AutoLISP® or the .NET Framework. But AutoCAD
LT still has plenty to offer in both the productivity and customization areas.
Because they’re so similar, we can present material for both programs with only
minor adjustments.
When a feature is discussed that is available only in AutoCAD 2018, you’ll see
the AutoCAD Only icon. For the purposes of this publication, the “ACAD only”
icon means that the relevant (or adjacent) content applies only to AutoCAD
software and not to AutoCAD LT software.
You’ll also see warning messages when tutorials vary between AutoCAD 2018
and AutoCAD LT. If only minor differences occur, you’ll see either a warning
message or directions embedded in the exercise indicating the differences
between the two programs.
We’ve also provided workaround instructions wherever possible when
AutoCAD LT doesn’t offer a feature found in AutoCAD 2018.
