NOTE NOTE
Illustrations in this textbook that display the command line show the command line
docked at the bottom of the AutoCAD window, above the status bar. This may be
different from the appearance you see on-screen. Where appropriate in this textbook,
the command line is shown fl oating to explain features associated with the fl oating
command line or to show additional command line history.
Depending on the command in progress, different information and options appear
at the command line. For example, Figure 1-21A shows the display after starting the
CIRCLE
command. The prompt line shows an icon and the name of the active command
followed by a prompt, which reads
Specify center point for circle
or. In this case, to draw
a circle, pick in the drawing window or enter coordinates to specify the center point of
the circle, or select a different option as suggested by the “or” portion of the prompt.
The square brackets ([]) contain available options. Select an option using the cursor or
type the name of the option. Each option has an alias, or unique highlighted upper-
case character(s), that you can enter at the prompt rather than typing the entire option
name. You can also select an option by right-clicking in the drawing window and
picking an option from the shortcut menu.
As you work with a command, the information displayed at the command line
changes. The active prompt background is white by default to distinguish it from
prompt and command line history, which is gray by default. When the command line
is docked, one line of command history appears by default. Figure 1-21B shows the
display after specifying the center point of the circle and entering the
Diameter
option.
At this prompt, you must specify the diameter of the circle. Some command prompts
include angle brackets ( ) surrounding the default option or value; press
[Enter]
to
accept the default instead of typing the value again.
To move the command line to a different location in the drawing window, pick
and hold the grab bar at the left edge and drag it. When the command line is fl oating,
three lines of command history appear by default. See Figure 1-22. Some commands,
such as the
FILLET
command active in Figure 1-22, display current command settings
as the fi rst line of prompt history after the command name for reference.
