AutoCAD 2007 is a premiere computer-aided designing program that lets you organize the objects you draw, their properties, and their files. It also helps you create great-looking models. But it's not always easy to figure out how to perform these functions, and many users end up missing out on AutoCAD's full potential.

AutoCAD 2007 For Dummies will show you how to perform these tasks and more! This hands-on guide lets you discover how to navigate around all the complications and start creating cool drawings in no time. Soon you'll have the tools you need to use DWG, set up drawings, add text, and work with lines, as well as:

• Draw a base plate with rectangles and circles
• Organize a successful template
• Zoom and pan with glass and hand
• Use the AutoCAD design center
• Navigate through your 3-D drawing projects
• Plot layout, lineweights, and colors
• Design block definitions
• Slice and dice your drawings to create new designs
• Create a Web format using AutoCAD

This book also features suggestions and tips on how to touch up your creations as well as ways to swap drawing data with other people and programs. Written in a friendly, straightforward tone that doesn't try to overwhelm you, AutoCAD 2007 For Dummies shows you the fun and easy way to draw precise 2-D and 3-D drawings!

Part I

AutoCAD 101

In this part . . .

**IN a DROPCAP**

AutoCAD is more than just another application program; it’s a complete environment for drafting and design. So if you’re new to AutoCAD, you need to know several things to get off to a good start — especially how to use the command line area and set up your drawing properly. These key techniques are described in this part of the book.

If you’ve used earlier versions of AutoCAD, you’ll be most interested in the high points of the new release, including some newer interface components. The lowdown on what’s new is here, too.

Using AutoCAD LT instead of AutoCAD

Upgrading from a previous version

Welcome to the community whose members are the users of one of the weirdest, wackiest, and most wonderful computer programs in the world: AutoCAD. Maybe you’re one of the few remaining holdouts who continues to practice the ancient art of manual drafting with pencil and vellum. Or maybe you’re completely new to drafting and yearn for the wealth and fame (would we lead you on?) of the drafter’s life. Maybe you’re an engineer or architect who needs to catch up with the young CAD hotshots in your office. Or maybe you’re a full-time drafter whose fingers haven’t yet been pried away from your beloved drafting board. Maybe you tried to use AutoCAD a long time ago but gave up in frustration or just got rusty. Or maybe you currently use an older version, such as AutoCAD 2000 or even (if you like antiques) Release 14.

Whatever your current situation or motivation, we hope that you enjoy the process of becoming proficient with AutoCAD. Drawing with AutoCAD is challenging at first, but it’s a challenge worth meeting. CAD rewards those who think creatively about their work and look for ways to do it better. You can always find out more, discover a new trick, or improve the efficiency and quality of your drawing production.

AutoCAD first hit the bricks in the early 1980s, around the same time as the first IBM PCs. It was offered for a bewildering variety of operating systems, including CP/M (ask your granddad about that one!), various flavors of UNIX, and even Apple’s Macintosh. By far, the most popular of those early versions was for MS-DOS (your dad can tell you about that one). Eventually, Autodesk settled on Microsoft Windows as the sole operating system for AutoCAD. AutoCAD 2007 works with Windows XP — Professional, Home, and Tablet PC editions — and Windows 2000.

Because of AutoCAD’s MS-DOS heritage and its emphasis on efficiency for production drafters, it’s not the easiest program to master, but it has gotten easier and more consistent. AutoCAD is pretty well integrated into the Windows environment now, but you still bump into some vestiges of its MS-DOS legacy — especially the command line (that text area lurking at the bottom of the AutoCAD screen — see Chapter 2 for details). But even the command line — oops! command window — has gotten kinder and gentler in AutoCAD 2007. This book guides you around the bumps and minimizes the bruises.

Why AutoCAD?

AutoCAD has been around a long time — since 1982. AutoCAD ushered in the transition from really expensive mainframe and minicomputer CAD systems costing tens of thousands of dollars to merely expensive microcomputer CAD programs costing a few thousand dollars.

AutoCAD is, first and foremost, a program to create technical drawings: drawings in which measurements and precision are important because these kinds of drawings often get used to build something. The drawings you create with AutoCAD must adhere to standards established long ago for hand-drafted drawings. The up-front investment to use AutoCAD is certainly more expensive than the investment needed to use pencil and paper, and the learning curve is much steeper, too. Why bother? The key reasons for using AutoCAD rather than pencil and paper are

Precision: Creating lines, circles, and other shapes of the exactly correct dimensions is easier with AutoCAD than with pencils.

Modifiability: Drawings are much easier to modify on the computer screen than on paper. CAD modifications are a lot cleaner, too.

Efficiency: Creating many kinds of drawings is faster with a CAD program — especially drawings that involve repetition, such as floor plans in a multistory building. But that efficiency takes skill and practice. If you’re an accomplished pencil-and-paper drafter, don’t expect CAD to be faster at first!

Figure 1-1 shows several kinds of drawings in AutoCAD 2007.

Why choose AutoCAD? AutoCAD is just the starting point of a whole industry of software products designed to work with AutoCAD. Autodesk has helped this process along immensely by designing a series of programming interfaces to AutoCAD that other companies — and Autodesk itself — have used to extend the application. Some of the add-on products have become such winners that Autodesk acquired them and incorporated them into its own products. When you compare all the resources — including the add-ons, extensions, training courses, books, and so on — AutoCAD doesn’t have much PC CAD competition.

The Importance of Being DWG

To take full advantage of AutoCAD in your work environment, you need to be aware of the DWG file format, the format in which AutoCAD saves drawings.

In some cases, an older version of AutoCAD can’t open a DWG file that’s been saved by a newer version of AutoCAD.

A newer version of AutoCAD can always open files saved by an older version.

Some previous versions of AutoCAD can open files saved by the subsequent one or two versions. For example, AutoCAD 2004 can open DWG files saved by AutoCAD 2006. That’s because Autodesk didn’t change the DWG file format between AutoCAD 2004 and AutoCAD 2006. However, the drawing file format did change with AutoCAD 200...
