The Edit Vertices tool edits vertex z-values stored with z-aware point, polyline, and polygon features. This tool is available on the Modify Features pane.
You can drag a vertex vertically, edit z-values individually, or apply the same value to multiple fields. In 3D scenes, to preserve the x, y coordinates of a vertex while dragging it, press and hold the H key.
Note:
The z-value field is a property of a feature class that is enabled when a feature class is initially created.
Z-values provide the ability to model and analyze point, polyline, and polygon features in three-dimensional (3D) space. For example, z-values can define the height of an aircraft or elevation changes along an underground transportation linear feature.
Clear or edit z-values
To clear or edit z-values in the geometry properties table, click the individual fields. To apply the same values to multiple rows, select the rows and click Update Z Values.
- On the Edit tab, choose your snapping preferences, and show the Modify Features pane.
- In the Snapping group, click the Snapping drop-down menu and enable your snapping preferences.
To temporarily turn snapping off while you edit a feature, press and hold the Spacebar.
- In the Features group, click Modify .
- In the Snapping group, click the Snapping drop-down menu and enable your snapping preferences.
- Expand Reshape and click Vertices .
- In the pane, click Select , and select a polyline or polygon feature.
- To refine the selection, right-click a feature in the tree view, and click Unselect or Only Select This .
- Clear or edit z-values in the geometry properties table.
- To clear an z-value and set it to NaN, click the field and press Backspace or Delete.
- To apply the same value to multiple vertices, select the rows, and click Update M Values .
- To finish the feature, right-click and click Finish , or press the F2 key.
Keyboard shortcuts
Edit vertices
Keyboard shortcut | Action | Comment |
---|---|---|
T+hover | Show vertices within the snapping tolerance. | Flash a square at vertices that are within the current snapping tolerance of the pointer. |
Ctrl+Shift+Click | Select multiple vertices. | Drag multiple segments in unison between the selected vertices. |
A+click | Add a vertex . | Create a vertex where you click a segment. |
D+click | Delete a vertex . | Delete the clicked vertex. |
H+drag | Edit the elevation. | Move a z-enabled vertex vertically and preserve its x,y coordinates. Hover over a control handle until the pointer becomes a vertex and drag the vertex. This shortcut is available in 3D scenes. |
Ctrl+drag | Move a Bézier curve. | Move a Bézier curve and preserve its shape. Hover over a curve until the pointer becomes a segment, and drag the curve. |
Ctrl+drag | Move a Bézier handle. | Move a Bézier control handle that can't otherwise be selected when it is coincident with another vertex. Hover over a control handle until the pointer becomes a vertex and drag the handle. |
Ctrl+H | Move the z-value to the pointer. | Move the z-value for the selected vertex to the elevation of the pointer. The x- and y-values are preserved. This is available only when stereoscopic mode is enabled. |
Ctrl+G | Move the pointer z-value. | Move the pointer z-value to the elevation of the selected vertex. This is available only when stereoscopic mode is enabled. |
