EXPLORING THE AUTOCAD AND AUTOCAD LT INTERFACE COMMUNICATING WITH THE COMMAND WINDOW AND DYNAMIC INPUT DISPLAY AutoCAD is the perfect servant It does everything you tell it to do and no more You communicate with AutoCAD by using tools and menu options These devices invoke AutoCAD commands A com mand is a single word instruction you give to AutoCAD telling it to do something such as draw a line the Line tool in the Draw Ribbon panel or erase an object the Erase tool in the Modify Ribbon panel Whenever you invoke a command either by typing it or selecting a menu option or tool AutoCAD responds by presenting messages to you in the Command window and the Dynamic Input display or by displaying a dialog box The messages in the Command window orin the Dynamic Input display often tell you what to do next or they may display a list of options A single command often presents a series of messages that you answer to complete the command These messages serve as an aid to new users who need a little help If you ever get lost while using a command or forget what you re supposed to do look at the Command window for clues As you become more comfortable with AutoCAD you ll find that you won t need to refer to these messages as frequently As an additional aid you can right click to display a context sensitive menu If you re in the mid dle of a command this menu displays a list of options specifically related to that command For exam
