About the Author
Mark Middlebrook used to be an engineer but gave it up when he discovered
that he couldn’t handle a real job. He is now principal of Daedalus Consulting,
an independent CAD and computer consulting company in Oakland, California.
(In case you wondered, Daedalus was the guy in ancient Greek legend who
built the labyrinth on Crete. Mark named his company after Daedalus before
he realized that few of his clients would be able to pronounce it and even
fewer spell it.) Mark is also a contributing editor for CADALYST magazine
and Webmaster of
markcad.com. When he’s not busy being a cad, Mark sells
and writes about wine for Paul Marcus Wines in Oakland. He also teaches
literature and philosophy classes at St. Mary’s College of California — hence
“Daedalus.” AutoCAD 2005 For Dummies is his sixth book on AutoCAD.

objects you draw, their properties, and the files in which they reside in
appropriate ways. You need to coordinate your CAD work with other people
in your office who will be working on or making use of the same drawings.
You need to be savvy about shipping drawings around via the Internet.
AutoCAD 2005 provides the tools for doing all these things, but it’s not always
easy to figure out which hammer to pick up or which nail to bang on first.
With this book, you have an excellent chance of creating a presentable,
usable, printable, and sharable drawing on your first or second try without
putting a T square through your computer screen in frustration.
What’s Not in This Book
Unlike many other For Dummies books, this one does tell you to consult the
official software documentation sometimes. AutoCAD is just too big and com-
plicated for a single book to attempt to describe it completely.
This book focuses on AutoCAD 2005, and also addresses its slightly less-
capable, much-lower-cost sibling, AutoCAD LT 2005. (AutoCAD LT 2005 For
Dummies, a version of this book especially for LT users, comes out several
b571389 intro.qxd 4/12/04 9:43 AM Page 1

months later than the regular book.) I do occasionally mention differences
with previous versions, going back to the highly popular AutoCAD Release 14,
so that everyone has some context and upgraders can more readily under-
stand the differences. I also mention the important differences between full
AutoCAD and AutoCAD LT, so that you’ll know what you — or your LT-using
colleagues — are missing. This book does not cover the discipline-specific
features in AutoCAD-based products such as AutoCAD Architectural Desktop,
except for some general discussion in Chapter 1, but most of the information
in this book applies to the general-purpose AutoCAD features in the AutoCAD
2005-based versions of those programs as well.
Who Are — and Aren’t — You?

The following sections describe the parts that the book breaks down into.
Part I: AutoCAD 101
Need to know your way around the AutoCAD screen? Why does AutoCAD
even exist, anyway? What are all the different AutoCAD-based products that
Autodesk sells, and should you be using one of them — for example,
AutoCAD LT — instead of AutoCAD? Is everything so slooow because it’s sup-
posed to be slow, or do I have too wimpy a machine to use this wonder of
modern-day computing? And why am I doing this stuff in the first place?
Part I answers all these questions — and more. This part also includes what
may seem like a great deal of excruciating detail about setting up a new draw-
ing in AutoCAD. But what’s even more excruciating is to do your setup work
incorrectly and then feel as though AutoCAD is fighting you every step of the
way. With a little drawing setup work done in advance, it won’t.
Part II: Let There Be Lines
In this part, it’s time for some essential concepts, including object properties
and CAD precision techniques. I know that you’re raring to make some draw-
ings, but if you don’t get a handle on this stuff early on, you’ll be terminally
(or is that monitor-ally? ) confused when you try to draw and edit objects. If
you want to make drawings that look good, plot good, and are good, read this
stuff!
After the concepts preamble, the bulk of this part covers the trio of activities
that you’ll probably spend most of your time in AutoCAD doing: drawing
objects, editing them, and zooming and panning to see them better on the
screen. These are the things that you do in order to create the geometry —
that is, the CAD representations of the objects in the real world that you’re
designing. By the end of Part II, you should be pretty good at geometry, even
if your ninth-grade math teacher told you otherwise.

with other people and accessing them from other computer programs.
There’s a lot of meat packed into these two chapters — juicy tidbits from
years of drafting, experimentation, and fist-shaking at things that don’t work
right — not to mention years of compulsive list-making. I hope that you find
these lists help you get on the right track quickly and stay there.
