Setting options for snapping

  1. Click the Map toolbar tab and click the Bookmarks menu to select the Digitizing roads bookmark. 

    The extent is just south of the point feature you created in the previous exercise.

  2. On the Edit toolbar, click the Snapping pull-down menu and click the Snap icon to ensure that snapping is on (highlighted).

  3. Look on the Snapping drop-down menu and confirm that End End Image Added, Vertex Image Added, and Edge Image Addedsnapping types are active. When enabled, the buttons are highlighted with a blue square. If they are not enabled, click each button to enable those agents.
  4. Click the Snapping pull-down menu and select Snapping Settings…

    From this dialog box, you can specify settings for snapping in ArcGIS Pro.

  5. Ensure the XY tolerance is at least 10 pixels.

    The snapping tolerance is the distance within which the pointer or a feature is snapped to another location. If the element being snapped to—such as a vertex or edge—is within the distance you set, the pointer automatically snaps to the location.

  6. Click OK to close the Snapping Settings dialog box.

  1. In the ‘Create Features’ pane, click the Local road line template[GSA3] , which is grouped under the Roads layer. This feature template was created for you and saved in the tutorial map document. 

    The list of available construction tools at the bottom of the pane changes to those used to create lines. Since the Line tool is the default tool for this template, it is activated automatically.

  2. Rest your pointer over the endpoint of the existing line in the western portion of the map display, as indicated below, but do not click yet. Notice that the pointer icon changes to a square snap symbol and a SnapTip appears with the name of the layer (Roads) and the snap type (Endpoint) in use. You can zoom or pan closer if you need to do so.
  3. Click once on the Roads: Vertex.

 

 

Using the aerial photo as a guide, digitize the new line by clicking the map each place you want to add a vertex.You digitize, or sketch, a new line or polygon by defining the feature's shape. You see a preview with the actual symbology used for that feature, with vertices symbolized as green and red boxes.Image Removed

4. Using the aerial photo as a guide, digitize the new line by clicking the map each place you want to add a vertex.

5.  In this exercise, you learned how to set up snapping and use it to help you digitize a new road that connects to existing roads.Once you have digitized the new line, snap to the end of the existing Roads feature and click to place a vertex there.

56. Press the F2 key, which finishes the sketch to turn your shape into an actual feature in the geodatabase. You can finish a sketch in one of several ways: pressing F2, double-clicking, or using the right-click shortcut menu or the pop-up Feature Construction toolbar.

In this exercise, you learned how to set up snapping and use it to help you digitize a new road that connects to existing roads.
