AutoCAD F11 Shortcut :Toggle object snap tracking

If you’re working in AutoCAD and want to speed up precise alignment and positioning, the AutoCAD F11 shortcut — which toggles Object snap Tracking — is one of the most useful tools to master. This guide explains what the F11 shortcut does, step‑by‑step how to use it, alternatives, common problems and fixes, plus practical tips to get the most from object snap tracking.

What is the F11 shortcut?

F11 in AutoCAD toggles Object Snap Tracking (the system variable OTRACK).

  • When Object Snap Tracking is active, AutoCAD displays temporary track lines and alignment cues from object snap points (endpoints, midpoints, centers, intersections, etc.), enabling you to locate points by aligning to existing geometry without creating construction geometry.
  • It works together with Running Object Snaps (F3) or with temporary snap overrides.

Important keywords: F11, Object Snap Tracking, OTRACK, Running Object Snaps (F3).

How Object Snap Tracking works (basic explanation)

  • With Object Snap Tracking enabled, when you hover near an object snap point (for example an endpoint), AutoCAD shows an inferred point and dashed tracking lines extending horizontally/vertically or along other constraint directions.
  • You can move the cursor along these tracking lines and pick a point that is aligned with a snapped point on another object.
  • This allows precise alignment without drawing reference lines or using extra objects.

How to use the F11 shortcut — Step by step

Step 1 — Ensure running object snaps are active

  • Press F3 to toggle Running Object Snaps on. Alternatively, click the Object Snap (OSNAP) button on the status bar and enable the snaps you need (endpoint, midpoint, center, intersection, etc.).
  • If running snaps are off, Object Snap Tracking has nothing to reference.

Step 2 — Toggle Object Snap Tracking

  • Press F11 to turn Object Snap Tracking on (press again to turn it off).
  • You can also type OTRACK at the command line and set it to 1 (on) or 0 (off).

Step 3 — Use tracking during a drawing command

  • Start a drawing or editing command that requests a point (for example LINE, MOVE, COPY, OFFSET).
  • Hover over an object to trigger an object snap (a small square or marker appears). AutoCAD will show a temporary inferred point and tracking lines.
  • Move the cursor to the desired intersection of tracking lines or along a tracking line and click to place the point precisely.

Example: Aligning the end of a new line to the midpoint of another line

  1. Press F3 to enable running snaps and ensure Midpoint is selected in OSNAP settings.
  2. Press F11 to enable object snap tracking.
  3. Start the LINE command. Hover over the midpoint of the existing line until the midpoint OSNAP marker and tracking lines appear.
  4. Move the cursor along the tracking line to intersect with an endpoint of another object and click — the new line endpoint will be aligned to the midpoint.

Alternative methods and commands

  • Use Polar tracking (F10) for angle‑constrained tracking when aligning at a fixed angle.
  • Use ORTHO mode (F8) to constrain cursor movement to horizontal/vertical directions.
  • Use the OTRACK command to control tracking numerically: type OTRACK and set to 1 (on) or 0 (off).
  • Use Shift + Right‑Click to open the object SNAP shortcut menu for temporary snap overrides while a command is active.
  • Use the Status Bar: click the Object Snap Tracking toggle icon or right‑click the OSNAP/tracking area and choose Settings to open drafting settings and configure tracking behavior.

Common reasons F11 (Object Snap Tracking) doesn’t work — and fixes

  • Reason: Running Object Snaps (F3) are off.
    Fix: Press F3 or enable desired snaps in OSNAP settings. Object Snap Tracking requires snap points to track from.

  • Reason: The OTRACK system variable is set to 0.
    Fix: Type OTRACK in the command line and set it to 1, or press F11.

  • Reason: Your keyboard’s function keys are locked by the OS or laptop Fn behavior (F11 may not send F11 to AutoCAD).
    Fix: Press Fn + F11 or toggle the laptop’s Fn Lock key / use BIOS/keyboard settings to switch Fn behavior. Alternatively, reassign shortcut in AutoCAD CUI.

  • Reason: A command is active that doesn’t accept point input or prevents tracking.
    Fix: End the current command and try again while a command that requests a point is active (e.g., LINE, MOVE).

  • Reason: CUI or custom workspace removed the F11 key assignment.
    Fix: Reassign or check the shortcut in the CUI (Customize user interface) dialog or use the OTRACK command.

  • Reason: visual feedback hidden or small Aperture/Pickbox size prevents snapping.
    Fix: Increase Aperture size in Options > Selection tab; enable visual tracking cues in Drafting Settings > Object Snap Tracking.

  • Reason: Conflicts with third‑party utilities or different keyboard mappings.
    Fix: Check other apps, disable conflicting utilities, or customize AutoCAD shortcuts.

Practical tips and best practices

  • Keep F3 (Running Object Snaps) and F11 (Object Snap Tracking) frequently used together — they complement each other.
  • Customize running object snaps to include only the snaps you need (endpoint, midpoint, center) to avoid clutter.
  • Use POLAR TRACKING (F10) and Object Snap Tracking together for angled alignments.
  • View the status bar indicators to confirm modes: when Object Snap Tracking is active the status icon appears highlighted.
  • If you work on a laptop, consider setting the Fn key behavior to avoid having to press Fn for F‑keys.
  • Use temporary snap overrides (Shift + Right‑Click) to snap one time without changing running snaps.

FAQ

What is the difference between F3 and F11 in AutoCAD?

F3 toggles Running Object Snaps (OSNAP): it enables snapping to points like endpoints, midpoints, centers. F11 toggles Object Snap Tracking (OTRACK): it uses those snap points to create temporary tracking lines and alignment cues. Both are often used together.

Why do I see no tracking lines after pressing F11?

Common causes: Running Object Snaps are off (press F3), OTRACK is set to 0 (type OTRACK and set to 1), or the command you’re using doesn’t accept point inputs. Also check Drafting Settings to ensure tracking markers are enabled.

How can I use F11 on a laptop if the F‑keys control media functions?

Press your laptop’s Fn + F11, enable Fn Lock, or change the keyboard behavior in BIOS/Windows settings. Alternatively, reassign the Object Snap Tracking command to a different shortcut in AutoCAD’s CUI.

Can I change the F11 shortcut to another key?

Yes. Open CUI (Customize User Interface), find the Object Snap Tracking command (OTRACK), and assign a different keyboard shortcut.

Is there an alternative to Object Snap Tracking for angle alignment?

Yes: use Polar Tracking (F10) for fixed angle alignment, and combine it with Object Snap Tracking for advanced alignment workflows.

Why do tracking lines sometimes snap to the wrong point?

This can happen if multiple running snaps are active or if your cursor aperture is too large. Limit running snaps to the ones you need, increase precision by zooming in, and adjust Aperture size in Options.

How do I permanently enable object snap tracking for every drawing?

Set OTRACK to 1 and save your workspace/profile. Configure running object snaps and Drafting Settings, then save the profile so these settings persist across sessions.
