Create a point or vertex at an inferred intersection

Intersection Intersection creates a point feature or a vertex at the inferred intersection of two segments. It is available on the construction toolbar when you create a point, line, or polygon feature using a feature template construction tool.

The intersection constructor operates transparently while you are drawing a feature. After clicking two existing segments and creating a vertex or a point feature, you can click a different construction method on the toolbar and continue drawing features.

For example, you can create a vertex at the inferred intersection of the outer walls of an L-shaped building and then use the line constructor to continue drawing a parking lot layout.

Create a point feature

  1. In the Catalog pane, do one of the following to add a polyline or polygon 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 point feature class.

    Creating a feature class or dragging one onto a map 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.
    Tip:

    You can press and hold the spacebar to temporarily turn snapping off as you draw a feature.

  3. If you are working with z-enabled features, on the Edit tab, in the Elevation group, choose how z-values are added to your features.
    Note:

    For steps to add z-values when creating z-enabled features, see Specify an elevation for 3D features.

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

    The Create Features pane appears.

  5. In the pane, click a point feature template and click Point Point.

    The construction toolbar appears at the bottom of the map.

  6. On the construction toolbar, click Intersection Intersection.

    The active draw mode temporarily suspends creating features.

  7. Click the two segments that, when extended, create an intersection.
    1. Click the first segment.
    2. Move the pointer and click the second segment.

    A point feature is created between the two locations.

  8. To continue creating point features, click Point Point on the construction toolbar.
  9. To finish the feature, click Finish Finish, or press F2.

Create a vertex

  1. In the Catalog pane, do one of the following to add a polyline or polygon 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 polyline or polygon feature class.

    Creating a feature class or dragging one onto a map 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.

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

    The Create Features pane appears.

  5. In the pane, click a line or polygon feature template.
    • To create a line, click Line Line
    • To create a polygon, click Polygon Polygon.

    The construction toolbar appears at the bottom of the map.

  6. You can click the map and begin creating a feature or use the tool to create the first vertex at the midpoint between two points.
  7. On the construction toolbar, click Intersection Intersection.

    The active draw mode temporarily suspends creating vertices.

  8. Click the two segments that, when extended, create an intersection.
    1. Click the first segment.
    2. Move the pointer and click the second segment.

    A vertex is created between the inferred intersection.

  9. To continue creating segments, click a line or arc tool on the construction toolbar.
  10. To finish the feature, click Finish Finish, or press F2.
