How to Restore a Missing AutoCAD Command Line (Complete Troubleshooting Guide)
The AutoCAD command line is one of the most important parts of the interface. Every command, prompt, warning, option, and system variable passes through it.
When the command line disappears, many users assume AutoCAD is malfunctioning. In most cases, the command line has simply been hidden, moved off-screen, minimized, or disabled accidentally.
This guide covers every reliable method to restore a missing command line in AutoCAD and AutoCAD LT, including Windows and macOS.
Quick Answer
If your AutoCAD command line is missing:
Windows
Press Ctrl + 9
Mac
Press Cmd + 9 (⌘ + 9)
If that does not work:
Step 1
Click inside the drawing area.
Step 2
Press Esc twice.
Step 3
Type:
COMMANDLINE
Step 4
Press Enter.
In most cases, the command line immediately returns.
Common Symptoms
Users describe this issue in many different ways:
- AutoCAD command line disappeared
- AutoCAD command bar missing
- AutoCAD command prompt not showing
- AutoCAD command window hidden
- AutoCAD command line off screen
- AutoCAD command line not working
- AutoCAD command line vanished
- AutoCAD command line missing after monitor change
- AutoCAD command line disappeared after docking station removal
The solutions below cover all of these situations.
Method 1: Use the Command Line Shortcut
The fastest solution is the built-in keyboard toggle.
Windows
Press:
Ctrl + 9
Mac
Press:
⌘ + 9
This shortcut toggles the command line on and off.
If AutoCAD asks whether you want to close the command line, click Yes, then press the shortcut again to force a fresh reload.
Note: The AutoCAD window must be active. If another application has focus, the shortcut will not work.
Method 2: Restore the Command Line by Typing Blindly
Even when the command line is invisible, AutoCAD continues accepting keyboard input.
Step 1
Click anywhere inside the drawing area.
Step 2
Press Esc twice.
This is important because AutoCAD may still be waiting for input from a command that is running in the background.
Step 3
Type:
COMMANDLINE
Step 4
Press Enter.
The command line should immediately reappear.
Method 3: Check Whether COMMANDLINEHIDE Was Used
Many users accidentally run the command that hides the command line.
Command That Shows the Command Line
COMMANDLINE
Command That Hides the Command Line
COMMANDLINEHIDE
Recovery Procedure
Step 1
Click inside the drawing area.
Step 2
Press Esc twice.
Step 3
Type:
COMMANDLINE
Step 4
Press Enter.
Method 4: Enable Dynamic Input
If you are unsure whether AutoCAD is receiving keyboard input, enable Dynamic Input.
Step 1
Press:
F12
Step 2
A floating command prompt appears near the cursor.
Step 3
Type:
COMMANDLINE
Step 4
Press Enter.
This restores the full command line window.
Method 5: Restore It from the Ribbon
You can manually reactivate the command line from the AutoCAD interface.
Step 1
Open the View tab.
Step 2
Locate the Palettes panel.
Step 3
Click Command Line.
Navigation path:
View → Palettes → Command Line
If the button already appears active, the command line is probably hidden off-screen.
Method 6: Exit Clean Screen Mode
Many users accidentally enable Clean Screen Mode.
This mode hides various interface elements and can make it appear that AutoCAD is broken.
Windows
Press:
Ctrl + 0
Mac
Press:
⌘ + 0
Alternative Method
Type:
CLEANSCREENOFF
and press Enter.
If the command line reappears, Clean Screen Mode was the cause.
Method 7: Switch Workspaces
Workspace files store interface layouts.
If a workspace becomes corrupted, switching workspaces often reloads the missing interface components.
Step 1
Click the Workspace Switching button.
Step 2
Choose another workspace.
Example:
Drafting & Annotation
to
3D Modeling
Step 3
Wait a few seconds.
Step 4
Switch back to your preferred workspace.
This forces AutoCAD to reload the workspace configuration.
Method 8: Recover an Off-Screen Command Line
This is one of the most common causes.
It frequently happens after:
- Disconnecting a second monitor
- Removing a docking station
- Changing screen resolution
- Moving between office and home workstations
AutoCAD remembers the previous position of floating windows.
The command line may still exist but be located outside the visible desktop area.
Step 1
Type:
COMMANDLINE
Press Enter.
Step 2
Press:
Alt + Space
Step 3
Choose:
Move
Step 4
Press any arrow key once.
This is the critical step. It attaches the hidden window to your cursor.
Step 5
Move your mouse.
The hidden command line should appear and follow the cursor.
Step 6
Click to place the command line back on-screen.
Method 9: Force Dock the Command Line Through CUI
If AutoCAD insists the command line is visible but you still cannot find it, force AutoCAD to dock it at the bottom of the screen.
Step 1
Type:
CUI
Press Enter.
Step 2
Expand:
Workspaces
Select your active workspace.
Step 3
Expand:
Palettes
Select:
Command Line
Step 4
Modify the following properties:
| Property | Value |
|---|---|
| Show | Yes |
| Orientation | Bottom (or Docked) |
Step 5
Click:
Apply
Step 6
Click:
OK
The command line should return to its default docked position.
Method 10: Check Whether the Command Line Is Minimized or Fully Transparent
Recent AutoCAD versions allow the command line to be resized, floated, and customized.
Sometimes the command line has not disappeared at all. It has simply been reduced to a tiny strip or made nearly invisible through transparency settings.
Fix a Minimized Command Line
Step 1
Move your cursor over the upper edge of the command line.
Step 2
Wait for the resize cursor to appear.
Step 3
Click and drag upward.
The command line expands back to its normal height.
Check Transparency Settings
If the command line is floating:
Step 1
Locate the command line options button (wrench icon).
Step 2
Right-click the icon.
Step 3
Review the Opacity setting.
If transparency is set too high, the command line may appear invisible.
Verify Dialog Settings
Type:
CMDDIA
Press Enter.
The value should normally be:
1
This ensures AutoCAD uses standard dialog boxes instead of forcing command-line-only interactions.
Method 11: Check Interface Lock Settings
Some interface elements may be locked.
The controlling system variable is:
LOCKUI
Common Values
| Value | Meaning |
|---|---|
| 0 | Unlocked |
| 15 | Maximum lock |
Step 1
Type:
LOCKUI
Step 2
Press Enter.
Step 3
Temporarily set the value to:
0
Step 4
Attempt to restore or reposition the command line again.
Method 12: Reset Your AutoCAD Profile
Profiles store many interface settings.
A damaged profile can cause missing panels and display issues.
Step 1
Type:
OP
Step 2
Press Enter.
Step 3
Open the Profiles tab.
Step 4
Select your active profile.
Step 5
Click Reset.
Step 6
Confirm the reset.
This restores profile settings without affecting your drawing files.
Method 13: Reset the Main CUIx File
If the interface customization file becomes corrupted, resetting it can restore missing UI elements.
Step 1
Type:
CUI
Step 2
Press Enter.
Step 3
Locate:
ACAD.cuix
or
ACADLT.cuix
Step 4
Right-click the file.
Step 5
Choose:
Reset
Step 6
Click Apply.
Warning
This removes:
- Custom Ribbon tabs
- Custom toolbars
- Custom shortcut keys
- Custom interface modifications
Use this method only after trying the earlier fixes.
Method 14: Use the AutoCAD Reset Settings Utility
If nothing else works, use Autodesk’s built-in reset utility.
Windows
Navigate to:
Start Menu
→
AutoCAD
→
Reset Settings to Default
Step 1
Launch the utility.
Step 2
Confirm the reset.
Step 3
Allow AutoCAD to rebuild its configuration.
This procedure often resolves severe interface corruption that profile resets cannot fix.
Warning
You may lose:
- Custom workspaces
- Tool palettes
- User preferences
- Ribbon customizations
Export important settings beforehand if possible.
