Extending a line by sketching
You can extend a line by digitizing new segments at the end of the existing sketch. For example, you might use this when updating a road by tracing over aerial photographs. You can resume sketching the shape of an existing line from the last vertex and add the new length to the road segment.
- To use Continue Feature, you must first add it to a toolbar from the Commands tab of the Customize dialog box. Click the Customize menu and click Customize Mode. Click the Commands tab and type Continue Feature in the search box. Drag the command onto any toolbar, such as the Editor or Edit Vertices toolbar.
- Click the Edit tool on the Editor toolbar and double-click the feature you want to edit.
- Click the Continue Feature tool on the toolbar to which you added it.
- You can resume sketching the feature and add segments from the last vertex, which is shown in red by default. Similar to digitizing a new feature, you have access to any available sketch construction methods. If you need to change the direction of the line so you can digitize from the vertex that is currently the first vertex, right-click the line and click Flip.
- To change the shape of the sketch segment, click a construction method type on the Editor toolbar or on the Feature Construction mini toolbar. Segments can be created using a variety of methods—for example, as straight lines, with curves, or traced from the shapes of other features. You can also use keyboard shortcuts or right-click to access a menu of commands to help you place vertices in the sketch.
- Right-click anywhere on the map and click Finish Sketch.
