Create densified line segments

In the Create Features pane, the Densify Lines setting is available with feature templates that create line features. Densifying a line segment inserts additional vertices on a new segment at even intervals that are specified as a sample distance in the tool pane. Arcs and curves are not densified.

Note:

This setting is not available in 3D scenes with this release of ArcGIS Pro.

Densify 2D line segments

A common use for densifying 2D line segments is to insert vertices for snapping from-to links when transforming features.

  1. In the Catalog pane, do one of the following to add a polyline layer to your map:
    • Expand Databases Databases, expand the database containing your data, and drag the feature class onto the map.
    • To create a new data source, right-click the default database, click New, click Feature Class Polygon feature class, type the feature class name, choose Polyline for the geometry type, choose the coordinate system, and click Run Run.

    The layer is added to the current map, and a feature template with default settings is automatically created.

  2. On the Edit tab, in the Features group, click Create Create Features.

    The Create Features pane appears.

  3. In the pane, click the polyline feature template.

    The template expands to show the tool palette, and the construction toolbar appears in the current map or scene view.

  4. Next to the tool palette, click the forward arrow Forward.

    The tool palette and the feature attribute table for the active template appear in the pane.

  5. Click Attributes Attributes and type the values you want to apply to the new feature.
  6. On the Edit tab, in the Snapping group, click the Snapping List By Snapping arrow and enable your snapping preferences.
    • To temporarily turn snapping off as you create the feature, press and hold the Spacebar.
  7. Click the Line Line construction tool.
  8. Check the Densify Lines check box.

    The arc segments tools are disabled on the construction toolbar

  9. In the Sample Distance text box, type the distance you want between each vertex.
  10. Click the map, drag the pointer, and click the map again.

    Notice the additional vertices that are autogenerated between the two points you clicked on the map.

  11. Continue creating the feature.
    Tip:

    As you create new geometry you can change the sample distance or turn Densify off to enable the arc and curve construction tools.

  12. On the editing toolbar, click Finish Finish, or press the F2 key.

Densify 3D line segments

A common use for densifying 3D line segments is to drape them onto an elevation surface. You can set a constant z-value or set the elevation mode to derive z-values from the active elevation surface as you sketch a line across a map.

For steps to add an elevation surface to a map, see Elevation surfaces.

  1. In the Catalog pane, do one of the following to add a z-enabled 3D polyline layer to your map:
    • Expand Databases Databases, expand the database containing your data, and drag the feature class onto the map.
    • To create a new data source, right-click the default database, click New, click Feature Class Polygon feature class, type the feature class name, choose Polyline for the geometry type, enable Z Values, select the coordinate system, and click Run Run.

    The layer is added to the current map, and a feature template with default settings is automatically created.

  2. On the Edit tab, in the Features group, click Create Create Features.

    The Create Features pane appears.

  3. In the pane, click the polyline feature template.

    The template expands to show the tool palette, and the construction toolbar appears in the current map or scene view.

  4. Next to the tool palette, click the forward arrow Forward.

    The tool palette and the feature attribute table for the active template appear in the pane.

  5. Click Attributes Attributes and type the values you want to apply to the new feature.
  6. On the Edit tab, in the Snapping group, click the Snapping List By Snapping arrow and enable your snapping preferences.
    • To temporarily turn snapping off as you create the feature, press and hold the Spacebar.
  7. Click the Line Line construction tool.
  8. on the Edit tab, in the Elevation group, click the Mode drop-down arrow Constant and enable one of the following z-value modes:
    • Constant mode Constant—Z-values are typed in the text box and applied to all vertices until you change the value.
    • Surface mode Surface—Z-values are derived from the active elevation surface when you click the map and the line is draped onto the surface.
  9. Check the Densify Lines check box.

  11. Click the map, drag the pointer, and click the map again.

  12. Continue creating the feature.
