Create adjoining polygons

In the Create Features pane, feature templates for polygon layers include Autocomplete Polygon Auto-Complete Polygon and Autocomplete Freehand Polygon Auto-Complete Freehand. These tools automatically trace the adjoining polygon boundary shared by the new feature.

Vertices for z-enabled 3D polygons are interpolated to follow the angular pitch of the adjoining polygon feature. For steps to specify z-values, see Specify an elevation for 3D features.

Autocomplete Polygon

To create an adjoining polygon, click Autocomplete Polygon Auto-Complete Polygon. Create the new polygon feature, cross the adjacent feature in at least two places, and click Finish Finish. The adjoining polygon boundary is automatically traced.

  1. In the Catalog pane, do one of the following to add the layer to your map:
    • Expand Databases Database Folder, 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 Polygon for the geometry type, 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 a polygon feature template.

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

    Construction toolbar
  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. 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.
  6. On the Edit tab, in the Snapping group, enable your snapping preferences, and move the pointer back to the map.
  7. Click Autocomplete Polygon Auto-Complete Polygon.
  8. Create the polygon, so that it crosses the adjacent feature or features in at least two places using one or more of the following methods:
    • Click the map, drag the pointer, and click the map again.
    • Right-click and use the context menu to specify x,y,z coordinate locations, distance, and direction.
    • To temporarily turn snapping off as you create the polygon, press the Spacebar.
    Note:

    Do not create the common boundary. If the new feature spans more than one feature, cross the first and last vertex across the same feature.

  9. To finish the feature, right-click and click Finish Finish or press the F2 key.

    The adjoining polygon boundary is automatically traced. Vertices for z-enabled 3D polygon boundaries are interpolated to follow the angular pitch of the adjoining polygon feature.

Autocomplete Freehand Polygon

To create an adjoining free-form polygon, click Autocomplete Freehand Polygon Auto-Complete Freehand. Click and drag the pointer to create the new polygon feature, cross the adjacent feature in at least two places, and click the map. The adjoining polygon boundary is automatically traced.

  1. In the Catalog pane, do one of the following to add the layer to your map:
    • Expand Databases Database Folder, 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 Polygon for the geometry type, 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 a polygon feature template.

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

  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. 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.
  6. On the Edit tab, in the Snapping group, enable your snapping preferences, and move the pointer back to the map.
  7. Click Autocomplete Freehand Polygon Auto-Complete Freehand.

    Snapping turns off temporarily until you finish the feature.

  8. Create the polygon by clicking and dragging the pointer so that the polygon crosses the adjacent feature in at least two places.
    Note:

    Do not create the common boundary. If the new feature spans more than one feature, cross the first and last vertex across the same feature.

  9. To finish the feature, click the map.

    Finish Finish runs automatically.

    The segments are converted to B├ęzier curves and the adjoining polygon boundary is automatically traced. Vertices for z-enabled 3D polygon boundaries are interpolated to follow the angular pitch of the adjoining polygon feature.
