Autocad Autocomplete Not Working | Fast, Reliable Fixes

AutoCAD autocomplete stops when command suggestions or Dynamic Input are off—turn on F12 and re-enable AutoComplete in INPUTSEARCHOPTIONS.

When command hints vanish mid-draft, every click slows down. This guide restores the command line suggestion list and keeps it stable across sessions. You’ll find quick toggles, system variables that control suggestions, and a short table that maps symptoms to fixes. Steps work in recent Windows and Mac releases of AutoCAD and AutoCAD LT.

Quick Fixes That Restore Suggestions

Goal: bring back the drop-down list that completes commands, system variables, and content names as you type.

Toggle Dynamic Input (F12) — Press F12. If the cursor input box was off, this brings it back and often revives near-cursor prompts tied to typing. You can also set DYNMODE to 1, 2, or 3 to enable it; 0 disables it. Autodesk KB, Help: Dynamic Input.
Re-enable AutoComplete — Type INPUTSEARCHOPTIONS and press Enter. In the dialog, tick Enable AutoComplete. Also tick Search System Variables, Search Content, and (if you want) Enable Mid-String Search. Help: INPUTSEARCHOPTIONS, Help: Command Line Suggestion List, Arkance tip.
Set AUTOCOMPLETEMODE — Enter AUTOCOMPLETEMODE and choose the behavior you want. This variable turns automated keyboard features on/off at the command prompt and controls how suggestions append as you type. Help: AUTOCOMPLETEMODE.
Show The Command Line — Press Ctrl+9 (Windows) or run COMMANDLINE. If it was hidden or undocked off-screen, suggestions won’t appear where you expect.
Reduce Suggestion Delay — In INPUTSEARCHOPTIONS, lower the Suggestion List Delay so matches appear faster. Long delays can look like no autocomplete at all. Help: Input Search Options Dialog.
Disable Clean Screen Mode — Press Ctrl+0. Clean Screen can hide UI elements that cue suggestions at the cursor.
Restart With A Fresh Profile — If the list still won’t return, reset settings to default (keeps a backup). This clears a damaged profile or CUI that can block autocomplete. Autodesk KB: Reset.

Why Command Hints Disappear

AutoCAD’s suggestion list depends on a small set of toggles and system variables. When any of them are off, the list can vanish or lag. Here’s what typically trips users up.

Dynamic Input Off — Cursor prompts and near-cursor typing go quiet when DYNMODE is 0. Autodesk KB.
AutoComplete Unchecked — The command line continues to accept input, but won’t suggest or auto-append items until AutoComplete is enabled in INPUTSEARCHOPTIONS. Help, Arkance tip.
Mid-String Search Disabled — Typing letters that aren’t the first characters of a command yields no matches unless Enable Mid-String Search is on. Help.
Suggestion Delay Too High — A long delay makes autocomplete feel broken; cut it down to get instant matches. Help.
Damaged UI/Profile — A corrupt CUI or profile can stop the list from drawing. A quick reset restores defaults. Autodesk KB.

Fix Autocad Autocomplete Not Working — By Setting

Work through the settings that most often resolve the issue. Each step lists what to check and the expected outcome.

Command Line Suggestion List

Open Options Fast — Type INPUTSEARCHOPTIONS. This opens the dialog that governs the list.
Enable AutoComplete — Tick Enable AutoComplete so the suggestion list appears as you type.
Show System Variables — Tick Search System Variables to include variables in results. Help: -INPUTSEARCHOPTIONS.
Include Content — Tick Search Content to match named objects (layers, blocks, etc.).
Allow Mid-String — Tick Enable Mid-String Search if you like to type fragments, not just prefixes.
Lower The Delay — Set the delay to a small value so the list pops up almost immediately. Dialog reference.

Dynamic Input And Cursor Prompts

Switch It On — Press F12. If prompts reappear by the cursor, you’re set.
Set DYNMODE — Enter DYNMODE and set 3 to enable both pointer and dimensional input. Help.

AUTOCOMPLETEMODE Behavior

Quick check: enter AUTOCOMPLETEMODE. Pick a setting that appends suggestions after a few characters. On Mac help pages, it’s described as turning on automated keyboard features and auto-appending after the third keystroke. Reference.

Show And Dock The Command Line

Bring It Back — Press Ctrl+9. If it was hidden, the list had nowhere to display.
Dock It — Drag the command line to the bottom edge so it snaps in place. Floating bars can hide behind other palettes.

AutoCAD Command Line Autocomplete Fixes (Windows & Mac)

This section groups fixes by platform so you can land on the exact switch you need.

Windows

Use The Dialog — INPUTSEARCHOPTIONS manages AutoComplete, AutoCorrect, system variable search, content search, and mid-string search from one place. Arkance: Fine-Tuning.
Cut The Delay — Lower the suggestion list delay in that dialog so keystrokes feel instant. Help.
Reset If Needed — Use the Reset Settings tool from Start menu to clear a faulty profile. Backups are created. Autodesk KB, Forum thread.

Mac

Check AUTOCOMPLETEMODE — Confirm automated typing features are on so suggestions append after a few characters. Help.
Reset From The App Menu — AutoCAD for Mac includes a Reset AutoCAD command under the program menu that restores defaults. Autodesk KB.

Symptom-To-Fix Table

Use this quick map when Autocad autocomplete not working blocks your flow in a deadline rush.

Symptom	Likely Cause	Fix
No suggestion list at the cursor	`DYNMODE` off	Press `F12` or set `DYNMODE` to `1-3`. Ref
List shows, but no auto-append	`AUTOCOMPLETEMODE` set low	Raise `AUTOCOMPLETEMODE` so text auto-appends. Ref
Only commands match, not variables	Search System Variables off	Enable in `INPUTSEARCHOPTIONS`. Ref
Typing inside a word shows no results	Mid-string search off	Tick Enable Mid-String Search. Ref
Delay before any hint appears	Suggestion delay too high	Lower delay in `INPUTSEARCHOPTIONS`. Ref
Nothing fixes it across drawings	Damaged profile/CUI	Reset AutoCAD to defaults. Ref

Deeper Checks When The Basics Don’t Stick

If Autocad autocomplete not working returns after a reboot, run these checks to lock the behavior in.

Test In A Clean Drawing — Open a blank file from the acad template. If suggestions work there, a custom drawing or template might be blocking the list.
Try A Blank Profile — Create a new profile in Options > Profiles, set it current, and test. A profile tied to old UI macros can mute suggestions.
Launch With /safemode — Start AutoCAD without third-party add-ins, then test typing. If autocomplete returns, re-enable plug-ins one at a time.
Repair Or Reset — Use the repair option in Windows Apps or the Reset command on Mac. This clears stubborn command line glitches. Reset guide.
Keep The Command Line Visible — Dock it and raise the prompt lines if needed with CLIPROMPTLINES so the list isn’t cramped.

Make Autocomplete Work The Way You Type

Once the list returns, tune it for speed so it stays helpful during long sessions.

Tailor Matches — In INPUTSEARCHOPTIONS, include commands, variables, and content so your first keystrokes reach the right items. Dialog reference.
Keep AutoCorrect In Check — If you prefer aliases like L for LINE, keep AutoCorrect on but remove pairs that fight your habits. Help.
Use Mid-String For Fuzzy Recall — When you can’t recall the start of a name, mid-string search lets fragments still match.
Fine-Tune Delay — Fast typists often prefer a tiny delay; slow typists may want a touch more to cut flicker.
Learn The Toggle — If prompts crowd the screen during point picks, hold F12 to temporarily turn Dynamic Input off, then release to bring it back. Help.

Still Stuck? Fast Paths To A Clean Slate

When every switch looks right and the list still refuses to show, go straight to a clean state.

Reset Settings — Use the built-in Reset wizard on Windows or the Reset menu item on Mac. Keep the backup so you can restore customizations later. Autodesk KB.
Rebuild CUIX — Export your current CUIX, reset, then import only the pieces you need. A dirty UI file often causes missing UI elements and odd command line behavior.
Check Startup Suite — Remove any startup LISP that loads UI changes for the command line; test again in a fresh session.
