Through a high level of technical innovation and expertise, Autodesk has created a program with unequaled features and capabilities, including 3D surface and solid modeling and visualization, access to external databases, intelligent dimensioning, importing and exporting of other file formats, Internet support, and much more. Autodesk has developed what it calls a virtual corporation.

Vẽ kỹ thuật với Autocad 2002 P24 Part I ✦ AutoCAD Basics Through a high level of technical innovation and expertise, Autodesk has created a program with unequaled features and capabilities, including 3D surface and solid modeling and visualization, access to external databases, intelligent dimensioning, importing and exporting of other file formats, Internet support, and much more. Autodesk has developed what it calls a virtual corporation. This “corporation” includes programmers who create software designed to work with AutoCAD (called third-party software), dealers (also called resellers) who provide technical support and training specific to a user’s field, and an education network that provides train- ing and courses to more than one million users each year. This setup provides a strong network of support to users throughout the world. The major disciplines that use AutoCAD are: ✦ Architectural (also called AEC for architectural, engineering, and construction) ✦ Mechanical ✦ GIS (Geographic Information Systems) ✦ Facilities management ✦ Electrical/electronic ✦ Multimedia However, AutoCAD has many other lesser-known uses, such as pattern making in the garment industry, sign making, and so on. In this book, I try to provide examples from many fields. The world of AutoCAD is very broad, and it is worthwhile to see the many approaches that AutoCAD makes possible. Starting AutoCAD This section starts the quick tour of AutoCAD, designed to make AutoCAD look easy and simple. The first step is to start AutoCAD. On the The CD-ROM contains a 15-day trial version of AutoCAD 2002. Look in CD-ROM \Software\AutoCAD 2002 Trial\Setup.EXE. This book covers AutoCAD 2002 running on Windows 98, Windows ME, Windows 2000, or Windows NT 4.0. Every computer is set up somewhat differently, so you may need to adjust the following steps slightly. If you didn’t install AutoCAD your- self and are unfamiliar with the folders (once called directories) on your computer, you should get help from someone who is familiar with your computer system. Chapter 1 ✦ Starting to Draw 5Cross- If you need help installing AutoCAD, turn to Appendix A.Reference By default, installing AutoCAD places a shortcut on your desktop, as shown in Figure 1-1. You can double-click this shortcut to launch AutoCAD. Of course, you can also choose Start ➪ Programs ➪ AutoCAD 2002. If a submenu opens, choose AutoCAD 2002 again. Figure 1-1: An AutoCAD shortcut on the desktop provides a quick way to open AutoCAD. Creating a New DrawingNew When you launch AutoCAD, AutoCAD Today, shown in Figure 1-2, appears asFeature a cover page on top of your AutoCAD drawing window. AutoCAD Today enables you to easily take advantage of your Internet and intranet connec- tions from within AutoCAD. Working with AutoCAD Today AutoCAD Today has three sections: ✦ The top-left area (My Drawings) enables you to create new drawings or open existing drawings. You can also access symbol libraries (sets of small draw- ings that you can insert into your active drawing). ✦ The top-right area, called the Bulletin Board, displays a Web page from the Internet or an intranet. This section is designed to be used by an AutoCAD Manager to communicate with AutoCAD users. ✦ The bottom area is a window into Point A, Autodesk’s Internet portal. These three areas are described in the next few sections of this chapter and in Chapter 2. To get right to work on your drawing, you can close AutoCAD Today by click- ing its Close button (the X at the top right of the window). You can always reopen it by clicking the new Today button on the Standard toolbar. AutoCAD Today opens in a smaller window than AutoCAD itself so you can also simply click anywhere visible on the AutoCAD screen to hide AutoCAD Today. You can then dis- play AutoCAD Today at any time by clicking its button on the Windows task bar. Tip If you don’t like AutoCAD Today, you can make it go away. Choose Tools ➪ Options and click the System tab. In the General Options section, click the Startup drop- down list and choose either “Show traditional startup dialog” or “Do not show a startup dialog.” The Startup dialog box offers similar options to AutoCAD Today.6 Part I ✦ AutoCAD Basics Figure 1-2: AutoCAD Today connects you with your manager, Autodesk’s Point A site, and makes it easy to create or open a drawing. You can collapse either the top or bottom section of AutoCAD Today by clicking the plus sign at the left of the section you want to collapse. Then click the minus sign to redisplay its section. You can also expand or contract the Bulletin Board by clicking its plus or minus sign. Cross- For more information on how managers can configure AutoCAD Today, see Reference Appendix A. Using AutoCAD Today to create a new drawing At the top left of AutoCAD Today is the My Drawings section, where you can create a new drawing or open any existing drawing. You can also access symbol libraries (collections of blocks that you can ...
