HOW TO EXECUTE AutoCAD COMMANDS

AutoCAD commands can be given in three ways: (1) use of pull-down menu bar; (2) use of icon; (3) use of the keyboard. Once the command is given, one will be prompted on the next step or required input data then press the Enter key to accept the inputs. When the command prompts are completed, the command can be terminated by pressing the enter key or the spacebar or the right button of the mouse.
