Turn snapping on or off

On the Edit tab, in the Snapping group, Snapping List By Snapping contains settings to manage how and when the pointer locks onto other features as you hover near them. These settings are also available on the status bar located at the bottom of an active map or scene.

Snapping enables you to accurately place or align features with other features. It can also be useful when measuring distances. Snap agents automatically snap the pointer to specific feature geometry, for example, to vertices, edges, or intersecting lines.

When you hover near a feature within the tolerance distance, textual feedback shows the active snap agents and the layer to which you are snapping. Optional settings include the XY tolerance in pixel or map units, the snap tip color, and snapping to unfinished sketch geometry.

For steps to turn snapping on or off for all features on a layer, see Turn snapping on or off by layer.

Turn snapping on or off

When you create or modify features, you can control the accuracy of your edits by turning snapping on or off as you work. Toggling snapping on or off does not change your snap agent settings.

  1. On the Edit tab, in the Snapping group, click Snapping List By Snapping.
    • Snapping is also available on the status bar at the bottom of the active map or scene.
  2. To temporarily turn snapping off as you work, press and hold the Spacebar.

Set snap agents

When you edit features, the best practice is to enable only the snap agents your work requires. For example, some workflows only require vertex and midpoint snap agents, while other workflows may require point, endpoint, and tangent snap agents.

  1. On the Edit tab, in the Snapping group, click the Snapping drop-down arrow List By Snapping.
    • On the status bar at the bottom of the active map or scene, you can also hover over the Snapping icon List By Snapping and use the pop-up dialog box.

  2. Click a snap agent to enable or disable it.

    Enabled snap agents appear shaded.

    Tip:

    To snap to point cloud data on a LAS dataset layer, enable Point Point.

  3. Move the pointer back to the map.

Snap agents

The following snap agents are available:

Snap agentsSnaps to

Point Point

Nearest point features and LAS data point features in 3D scenes.

Endpoint Endpoint

Nearest start or endpoint of a polyline or polygon

Vertex Vertex

Nearest vertex of a polyline or polygon

Edge Edge

Nearest polyline or polygon segment

Intersection Intersection

Nearest intersection of two or more polylines or polygons

Midpoint Midpoint

Midpoint of the nearest polyline or polygon segment

Tangent Tangent

Nearest point of tangency on an arc or curved polygon segment

Change snapping settings

For most workflows, using the default settings is the best practice. If you need to change them, optional settings include the XY tolerance in pixel or map units, the snap tip color, and snapping to unfinished sketch geometry.

  1. On the Edit tab, in the Snapping group, click the Snapping drop-down arrow List By Snapping.
    • On the status bar at the bottom of the active map or scene, you can also hover over the Snapping icon List By Snapping and use the pop-up dialog box.
  2. Click Snapping Settings Options.
    Snapping Options
  3. Change one or more of the following settings:
    • XY tolerance—The XY distance from a feature where the enabled snap agents become active. You can choose map or pixel units.
    • Z tolerance (2D only)—The Z distance from a feature where the enabled snap agents become active.
    • Snap tip color—The color of the text feedback that appears near the pointer.
    • Snap to sketch— When enabled, the pointer snaps to unfinished geometry.
  4. Click OK.

    Your settings are saved and the dialog box closes.
