Have You Tried: Take Control of the Command Window

You can start commands from a user interface element, such as the ribbon or toolbar, or enter them directly at the Command prompt. Entering commands directly at the Command prompt can be more efficient than trying to locate them on the ribbon or a toolbar. Even for people who use AutoCAD every day, it’s easy to overlook some of the productivity features available for the command window.

In the command window you can:

When you start typing, the letter L in this example, available commands and system variables are displayed in a list. We call this the AutoComplete list. You can then choose the command or system variable you want to use.

Configure AutoComplete

AutoComplete allows you to quickly find a command, system variable, or named object based on a list of suggestions. The items shown in the AutoComplete Suggestions list can be filtered by entering one or more letters at the Command prompt. By default, the suggestions listed either start with or contain the letters as you type them.

  1. In the command window, click the Customize button.

  2. On the menu, click Input Search Options.
  3. In the Input Search Options dialog box, make sure the options match the default input search settings used to populate the AutoComplete Suggestions list as shown below.

  4. Click OK.
Note: Some of the same functionality of the AutoComplete feature is available at the crosshairs cursor when Dynamic Input is turned on. Dynamic Input can be turned off by entering DYNMODE at the Command prompt and setting it to 0 or the negative of the current value (for example, a setting of 3 would become -3 to turn it off).

Use AutoComplete to Find a Command or System Variable

As you enter text in the command window, the AutoComplete Suggestion list becomes filtered based on that letter sequence.

  1. Click in the command window and type line but don’t press Enter.

    After a short delay, the AutoComplete Suggestions list appears and is filtered based on the entered text. Commands and command aliases that match the entered text are listed at the top, while system variables are grouped under the first expandable section. Matching hatch patterns and named objects display in other collapsible sections under the system variables.

  2. Click the PLINE item to start the PLINE command.
  3. Press ESC to cancel the current command.
  4. At the Command prompt, type line again.
  5. In the AutoComplete Suggestion list, click the System Variables grouping to expand it.

  6. Move the cursor over the PLINETYPE item.
  7. Click the Search in Help icon () to display information about the PLINETYPE system variable in the Help window.

    You can also press F1 when a command is active or when the mouse pointer is hovering over an item in the AutoComplete Suggestion list.

Tip: You can use command aliases to decrease the amount of time it takes to start a command; rather than moving the mouse cursor around the user interface to locate a command, the mouse cursor can remain in the drawing area and ready to provide input. A command alias is a shortened name for a command, often one or two letters in length. The AutoComplete Suggestion list displays command aliases with the command to be started in parentheses. A full list of all command aliases can be viewed or printed by clicking Manage tab > Customization panel > Edit Aliases > Edit Aliases.

Use AutoComplete to Set a Layer Current and Insert a Block

By default, named objects are listed in the AutoComplete Suggestion list. If you know the name of the layer you want to set current or the block to insert, you can type the name at the Command prompt. Typing the name of a commonly used layer or block can be more efficient than scrolling through the Layers drop-down list or Blocks gallery on the ribbon.

  1. Open a drawing that contains some layers and blocks.
  2. In the command window, enter the name of the layer to set current.

    The value of the CLAYER system variable is changed to the name of the layer you entered.

  3. In the command window, enter the name of the block to insert.

    The -INSERT command starts and allows you to insert the block.

Note: This functionality is only available in the command window, and not from the Dynamic Input tooltip that appears near the crosshairs.

Use a Recent Command or Entered Value

AutoCAD maintains a history of recently used commands and entered values.

  • Use a Recent Command – Press the Up or Down Arrow keys to step backwards or forwards through a list of recently used commands.

    Alternatively, you can right-click in the command window and choose a command from the Recent Commands submenu.

  • Use a Recent Value – While a command is active, press the Up or Down Arrow keys to step backwards or forwards through recent values provided at the same or similar prompts. As you step through coordinate values, a glyph appears in the drawing indicating the coordinate point in the drawing.

    Alternatively, you can right-click in the drawing window and choose a value from the Recent Input submenu.

Change the Appearance of the Command Window

The color and font used by the command window can be changed if you find the default colors and font hard to read.

  1. In the drawing window, right-click and choose Options.
  2. In the Options dialog box, Display tab, under Windows Element, click Colors.

  3. In the Drawing Window Colors dialog box, under Context, choose Command Line.

  4. In the Interface Element list, choose the element of the Command and Text window to change.
    • Command History – Expanded part of the Command and Text windows
    • Active Prompt – Bottom most line in the Command and Text windows
    • Temporary Prompt – Previous prompt messages that are displayed above the Command Line window when it is floating and displaying only one row
    • Command Option – Keywords listed in the active command’s prompt

    The Text window can be displayed by pressing F2 while the command window is docked or Ctrl+F2 when the command window is floating. The Text window allows you to see the command history of the current drawing.

  5. Click the Color drop-down list and choose a new color for the selected element.
  6. Repeat Steps 4 and 5 for each element to change.
  7. Click Apply & Close to save the changes.
    Note: Use the Restore buttons to reset the colors of the selected element or context, or all elements in all contexts.
  8. Click Fonts.
  9. In the Command Line Window Font dialog box, change the font, font style, and size options for the text displayed in the Command and Text windows.

  10. Click Apply & close to save the changes.
  11. Click OK to save all changes made and exit the Options dialog box.

The following explains how to change the height and dock the command window.

  • Change the Height of the Command Window – Move the cursor to the top edge of the command window and drag the edge up or down to increase or decrease the number of rows displayed.

  • Change the Width of the Command Window when Floating – Move the cursor to the right edge of the command window and drag the edge right or left to increase or decrease the width of the command window.

  • Dock the Command Window – Click and hold the mouse button over the grip on the left edge of the command window and drag the window to a new location at the top or bottom edge of the drawing window. Release the mouse button when the command window arrives.

FAQ: Where Did My Command Window Go?

While looking at customer feedback related to the command window, there were many comments related to the disappearance of the command window. In many cases, the command window was turned off accidentally or lost as the result of switching display resolutions. Switching display resolutions can cause the command window to appear off-screen and make it difficult to reposition within the new screen limits.

The following bullets explain how to redisplay the command window. The solutions are listed from easiest and least intrusive to most complex and risky:

  • Toggle the display of the Command Window - Do one of the following:
    • On the ribbon, click View tab > Palettes panel > Command Line Find
    • Press Ctrl+9
    • At the Command prompt, enter COMMANDLINE
  • Modify the Current Workspace - On the ribbon, click Manage Tab > Customization panel > User interface. In the Customize User Interface editor, select the current workspace under the Workspaces node; the current workspace has '(current)' appended to its name. In the Workspace Contents pane, on the right, expand the palettes node and select Command Line. In the Properties pane, set Show to Yes and Orientation to Bottom. Then click Apply to save the changes; the command window should appear floating along the bottom of the drawing window. Change Show and Orientation back to 'Do Not Change' and click OK to restore the default behavior.
  • Reset the Current AutoCAD Profile – At the Command prompt, enter OPTIONS. In the Options dialog box, Profiles tab, make sure the user profile you want to reset is set current. Click Export and save a copy of your user profile to a safe location. Click Reset and then click Yes to reset the AutoCAD user profile.
