NOTE When Dynamic Input is turned on and is set to display dynamic prompts,
you can enter commands and options in tooltips near the cursor. Dynamic Input
can be turned on an off from the status bar.
Display Valid Commands and System Variables
By default, AutoCAD automatically completes the name of a command or
system variable as you type it. Additionally, a list of valid choices is displayed
from which you can choose. Use the AUTOCOMPLETE command to control
which automatic features that you want to use.
If the automatic completion feature turned off, you can type a letter on the
command line and press TAB to cycle through all the commands and system
variables that begin with that letter. Press Enter or Spacebar to start the
command or system variable.
Enter Alternate Names of Commands
Some commands also have alternate names. For example, instead of entering
circle to start the CIRCLE command, you can enter c. Command aliases are
defined in the acad.pgp file.
To define your own command aliases, see Create Command Aliases in the
Customization Guide.
Specify Command Options
When you enter a command in the Command Line, you see either a set of
options, a dialog box, or a palette. To specify an option displayed in the
Command line, enter the capitalized letters for the option. For example, when
you enter circle, the following prompt is displayed:
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]:
You can specify the center point for the circle either by entering X,Y coordinate
values, or by using the pointing device to click a point in the drawing area.
To choose a different option, enter the letters capitalized in one of the options
in the brackets. You can enter uppercase or lowercase letters. For example, to
choose the three-point option (3P), enter 3p.
Repeat and Cancel Commands
You can repeat the previous command by pressing Enter or Spacebar.
