Chapter 1 Introduction to AutoCAD 19 Copyright Goodheart-Willcox Co., Inc. PROFESSIONAL TIP P R OFESSIONAL TIP Certain AutoCAD dialog boxes can be resized. Resize dialog boxes as needed to view hidden content and reduce the need to scroll through long lists. The size of the dialog box is maintained when you exit and then restart AutoCAD. CAUTION CA U TION The AutoCAD interface includes several other unique items, such as fi le tabs, the view- port controls, the navigation bar, the view cube, and Model and Layout tabs. Refer to Figure 1-5 to recognize these features. You will explore these features and their specifi c controls throughout this textbook. Do not use or adjust these tools until you learn about their functions, because doing so can unexpectedly change the interface display and operation. Ensure that the Model tab is active. Exercise 1-9 www.g-wlearning.com/CAD/ Complete the exercise on the companion website. AutoCAD Options The Options dialog box contains AutoCAD system and drawing fi le options. System options apply to the entire program. Drawing fi le options, identifi ed by the AutoCAD drawing icon, are fi le-specifi c. Many system options are available to help confi gure the work environment, such as the background color of the drawing window. This textbook focuses on the default system options and references the Options dialog box when applicable. NOTE NOTE You can also access the Options dialog box by right-clicking when no command is active and selecting Options…. Accessing Commands Acce ss ing Comm a nd s Commands are available by direct access from the ribbon, shortcut menus, Application Menu, Quick Access toolbar, palettes, status bar, fi le tabs, viewport controls, navigation bar, and view cube. An alternative is to enter the command using dynamic input or the command line. The basic method to activate a command by typing is to type the single-word command name or the command alias and press [Enter] or the space bar, or right-click. You can use uppercase, lowercase, or a combination of upper- case and lowercase letters. You can only issue one command at a time. You can activate any command or option by typing. Each command name and alias, along with other access techniques available in the Drafting & Annotation work- space, appears in a graphic in the margin of this textbook. The example displayed in this margin shows the command name (LINE) and alias (L) you can enter to access the LINE command.
