■
Menu Browser access is from the bright red button at the top-left corner of the application
window. All the commands for the tutorials in this book are accessible from these menus.
■
The Object Snap menu is displayed when you hold down SHIFT and click the right mouse button.
Object snaps facilitate precision drawing by snapping the cursor onto a feature on an object such
as the endpoint of a line or the center of a circle.
■
Shortcut menus are displayed when you click the right mouse button. Different menus are
displayed when you right-click an object, right-click in the drawing area, right-click a toolbar, or
right-click within a dialog box, palette, or window.
Start Commands on the Command Line
You can initiate commands by typing them on the command line within the command window instead
of using toolbars or menus. Additionally, some commands must be completed on the command line,
regardless of how they are started.
Some commands have abbreviated names or command aliases . For example, you can enter c as an
alias for CIRCLE.
After you type the command on the command line, press ENTER or SPACEBAR to start the
command. You can also repeat the previous command by pressing ENTER or SPACEBAR.
NOTE In this guide and in the Help system, when you are instructed to enter something, type the bold-
face value on the command line, and then press the ENTER key.
Specify a Command Option
When you start a command, you will often see a set of options on the command line. For example,
when you enter the CIRCLE command, the following prompt is displayed on the command line:
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]:
The default option, “Specify center point for circle,” is displayed before the square brackets. Alternate
options are displayed between the aquare brackets.
■
To accept the default option, enter coordinate values, or use the pointing device to click a center
point in the drawing area.
■
To choose a different option, enter the capitalized letters in the option name. For example, type
2P and press ENTER to choose the Two-Point option.
