The Edit Vertices mini toolbar provides quick access to some of the most commonly used commands when editing vertices. It appears on the bottom-center of the screen whenever either the Edit tool or the Topology Edit tool is active and you are editing the vertices of a feature or topology edge. You will drag the vertices and handles to edit the shape of a line that was poorly digitized on a trailhead that starts at a road and ends near a stream.
- Above your map display, click the 03 Editing Features map.
- Click the Bookmarks drop-down menu on the Map toolbar and select the Trail bookmark.
- Click the Edit toolbar and click the Select tool.
- Select the trail line (the brown and gray dashed line) that connects to the road.
- On the Edit toolbar, click the Vertices tool.
When you are viewing the sketch geometry of a feature, the Edit Vertices toolbar appears, giving you quick access to commands used when editing a feature's vertices and segments.
When compared to the aerial photograph, notice that this line is straight when it should be curved, and it also has some extra vertices. You can easily change a straight segment into a circular arc or Bézier curve, and vice versa, and delete the extra vertices. A Bézier curve is smooth and has on each of its two endpoints handles that can be moved to change the direction and the steepness of the curve. You can create Bézier curves by digitizing them using the Bézier Curve sketch construction method or by using certain editing commands, such as Smooth on the Advanced Editing toolbar. - Move your pointer over the middle of the trail line segment closest to the road, as shown below, and notice that the pointer changes to indicate you are working with a segment.
- Right-click the middle of the trail line segment and selectChange Segment > Circular Arc.
The segment changes to an arc. - Click, drag, and drop the arc over the trail on the aerial photograph. You can hold down the SPACEBAR key to turn off snapping temporarily if you are having difficulty placing the curve where you want it, because it is snapping to its original location.
- Click the map away from the new line feature to update its shape.
- Double-click the trail line feature, which accomplishes the same thing as using the Edit Vertices button.
- On the Edit Vertices mini toolbar, click the Delete Vertex tool.
- Draw a circle around the three vertices that form a zigzag shape between the previous segment and the horizontal segment, as shown below.
This deletes those vertices, as they are in the incorrect locations and are not needed to maintain the shape of the line in this area. - On the Edit Vertices toolbar, click the Normal Vertices tool
(the white Edit tool).
This allows you to continue working with the segments and vertices. - Right-click the northernmost trail line segment and selectChange Segment > To Bézier Curve.
A new set of Bézier curve handles is added, and the segment changes into an S-shaped curve. You can see the locations of the vertices and handles, which are displayed in blue. - Rest your pointer over a green vertex, then rest it over a blue handle.
You get different pointer icons depending on the type of point you are over. - Drag the blue handles to reshape the curve to match the aerial photograph, as shown below.
- Click the map away from the trail line feature to update the changes to its shape.
If you need to refine the line's shape further, double-click it again with the Edit tool and modify the segments. If you want to insert or delete a vertex, use the tools on the Edit Vertices toolbar. - On the Edit toolbar, click Save.
- You changed segments into different types and edited vertices.
