Create segments by streaming vertices

Streaming Streaming creates a free hand sketch by streaming vertices and then simplifies the sketch into a series of line segments within a specified tolerance. The tool is available on the construction toolbar and context menu when you create polyline or polygon features.

Clicking the map while streaming suspends the tool and allows you to choose another construction tool or continue streaming.


This construction tool is not available when you edit a stereo map using the Image Analyst extension with this release of ArcGIS Pro.

  1. In the Catalog pane, do one of the following to add the layer to your map:
    • Expand Databases Databases, expand the database containing your data, and drag the feature class onto the map.
    • Right-click the default database and create a new polyline or polygon feature class.

    Dragging or creating a feature class adds the layer to the current map and creates a feature template with default settings.

  2. On the Edit tab, in the Snapping group, enable your snapping preferences.

    As you sketch the feature, you can press and hold the spacebar to temporarily turn off snapping.

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

    The Create Features pane appears.

  4. Click a polyline or polygon feature template.

    The construction toolbar appears at the bottom of the map.

  5. Next to the tool palette, click the Active template button Forward.

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

  6. In the attribute table, type the values you want to apply to the new feature.
    • For group templates, click a template icon to display its attribute table.
  7. On the construction toolbar, click the trace tools drop-down menu and choose Streaming Streaming, or press F8.

  8. Click the map to start streaming.
    1. Press O to open the Stream Options dialog box and change the stream tolerance in map units.

      The default tolerance of zero (0) creates overlapping vertices. You can change the tolerance at any time as you stream vertices.

  9. Drag the pointer across the map to stream vertices.
  10. Click the map to suspend streaming.

    The streamed vertices are simplified into a series of line segments within the specified tolerance.

  11. To continue creating segments, do one of the following:
    • Click the map to resume streaming.
    • Choose another segment construction tool.
    • To resume streaming after using another construction tool, click Streaming Streaming, or press F8.
  12. On the construction toolbar, click Finish Finish or press the F2 key.
