The Edit Vertex functionality allows you to change the geometry of your created survey data by allowing you to move existing, create new, and delete vertices of your generated survey data. The Edit Vertex Mode functionality can only select one piece of data at a time. You can enable the Edit Vertex feature in the TOOLS for Polyline/Boundary tab and the edit dialog box will appear.
Edit Vertex in the TOOLS Tab
Edit Vertex in the Mini Toolbar
Right click in the Viewport with a point, polyline, or boundary selected.
Available Edit Vertex Modes with Different Plans
| Valley Interface | Ridge/Mountain Interface | Peak Interface |
|---|---|---|
 |  |  |
Edit Vertex works on:
- Points (the Interpolate Z function does not work on points)
- Polylines (arc included)
- Boundaries (circle and rectangle included)
Info! Any edit done to the vertices can be undone using Ctrl+Z or by clicking the Undo button in the Quick Access Toolbar.

Edit Vertex Modes
Editing existing vertices can be done in 4 different ways.
| Mode | Description |
|---|---|
| On Terrain | Allows you to change the position of one or multiple vertices using your mouse while placing the vertex Z level on the underlying drone data. |
| XY | Allows you to change the position of one or multiple vertices using your mouse while maintaining its current elevation. |
| Z | Allows you to change the elevation of one or multiple vertices using your mouse or the Z input field. |
| Interpolate Z (Linear) | Creates a change to the elevation of a range of vertices by interpolating the Z values between two vertices on a linear line. |
| Interpolate Z (Curve) | Creates a gradual elevation change to the slope of a range of vertices by interpolating the Z values between two vertices on a curved line. |
Selecting Vertices
Once you have enabled any of the available edit modes, you can select a vertex or multiple vertices to edit.
- Select a single vertex. The vertices appear as white dots in edit mode; you can select them with a left-click and the vertex will appear purple once it is selected.
- Select multiple vertices. Hold Ctrl with each left-click, or you can select a range of vertices holding the Shift key down.
- Select all vertices. Press Ctrl+A to select all vertices at the same time.
- Cycle through vertices. You can move the selection to the next or previous vertex, using the arrow keys.
Examples of Edit Vertex Modes
On Terrain
Selecting the On Terrain option will allow you to drag the vertex to a new location with the Z being determined by the underlying drone data. You can also move multiple vertices at the same time.
Edit XY
When the XY mode is enabled, you click and drag a single vertex (or multiple vertices at the same time) anywhere along the XY axis and their Z elevation will stay locked at the height it started from.
Edit Z
When you are in the Z Edit mode, dragging a vertex will hold the XY position of the selected vertex while allowing the movement of the vertex in the Z direction. When moving a vertex (hold left-click and drag), an orange line appears to provide spatial context during the edit operation. You can also enter a specific elevation for the vertex in the input field or use the arrows to change the elevation to the value you want.
Interpolate Z (Linear)
When you are in the Interpolate Z (Linear) mode, selecting a range of vertices changes the elevation of those vertices to become a constant slope between two vertices. Left-click on the first desired vertex, then left-click again on the last desired vertex—from the same polyline—to apply the interpolation.
Interpolate Z (Curve)
When you are in the Interpolate Z (Curve) mode, selecting a range of vertices changes the elevation of those vertices to become a gradual slope between two vertices. Left-click on the first desired vertex, then left-click again on the last desired vertex—from the same polyline—to apply the interpolation.
Add a Vertex
With the Edit Vertex tool enabled, you can add a vertex to a polyline or a boundary by clicking on the segment between 2 existing vertices. Depending on the enabled edit mode, the new vertex is either draped onto the terrain (On Terrain) or it is created at the elevation between the 2 existing vertices.
Delete a Vertex
Again, with the Edit Vertex tool enabled on a selected polyline/boundary, select a vertex or a group of vertices to delete them. Pressing the Delete key deletes any selected vertex, and the selection automatically moves to the next vertex. This allows for quick deletion of a sequence of vertices by pressing the Delete key multiple times. You can also select multiple vertices using Shift or Ctrl keys and delete them in groups. This operation for deleting vertices is shown in the illustration below, where a bulge (generated with Extract Level) is deleted to extract a correct water boundary.
Geometry Snapping
With the geometry Snapping feature, you can accurately connect existing geometry together. When you are using a drawing tool with Geometry Snapping enabled, your cursor will turn into a purple circle if it comes close to an existing geometry. Left click when the purple circle appears to start the drawing from that existing vertex or segment.
Differences Between Edit Vertex, Move/Copy, and Offset Z
These three tools do have some overlap between functionality, however they each have a specific purpose. Knowing how to use each one in context can help you be much more efficient with your time:
- Edit Vertex
- Only edits the selected (individual or multiple) vertices based on the functions of the Edit Vertex Modes.
- This tool is best used when you need to manipulate a portion of the polyline/boundary with any project.
- Move/Copy
- Moves or copies the entire drawing as a complete geometry on an XY axis and keeps the vertices in the same position as the original polyline/boundary.
- This tool is best used for planimetric or design projects when you need to create a copy or move the entire geometry of your polyline/boundary.
- Offset Z
- Moves the entire drawing as a complete geometry on the Z axis and keeps all vertices in the same position as the original polyline/boundary.
- This tool is best used for design projects when you need to raise or lower the elevation of the entire geometry of your polyline/boundary.
