FLOATING COMMAND LINE
When you first start AutoCAD, and if the software has not been modified, the Command Line will be displayed at the bottom of the screen, as shown below.
This is where AutoCAD will prompt you for information and you will enter commands, values and select options. Basically this is how you communicate with AutoCAD.
You may “dock” the command line at the top or bottom of the AutoCAD window or let it float in the drawing area.
To move the command line, place the cursor on the left end grip, press the left mouse button and drag the command line to a desired location.
To “dock” the command line drag it to the top or bottom of the drawing area. It will snap to the edge. You can’t dock the command line to the sides.
You may also drag it below the drawing area as shown below.
Note: You may toggle the Command Line ON and OFF using Ctrl + 9.
COMMAND LINE
How to enter a command on the Command Line.
1. Type the first letter of a command, such as c for circle.
2. A list of commands that begin with the letter c will appear. Select the desired command from the list.
3. When you enter a command such as Circle, the prompt and options will be displayed on the command line.
4. The prompt for Circle command asks you to:
“Specify center point for circle” or [3P/2P/Ttr (tan tan radius)]:
The information within the [ ] brackets are options that you may select.
Clickable options are displayed in blue.
Options displayed in Black must be typed or selected from the option menu.
This will be discussed more in Lesson 2. Or for more advanced Command Line options, see Appendix-D.
