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.  

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.

In the example below, we need to edit a vertex on a polyline to extend the road line to the boundary while ensuring the vertex remains on the terrain. By default, the vertex will snap to the boundary line (indicated by a purple dot). To override this, hover over the snapping point and press Tab to see options of where you can place the vertex. Press Tab again to cycle through the options, then select On Terrain to place the point at ground level.

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. In the example below, we've placed a point next to the rock pile at ground level and we want to move the vertex to the wall at the same XY elevation.

You can also align a vertex with other geometry and still maintain the XY plane. As an example, we'll move two end vertices simultaneously to extend the slope at the edge of a road, and ensure the vertices remain aligned with the drainage systems in the image shown below. First, we move the vertex over the drainage edge line, allowing it to snap to the drainage geometry. Then, using the dotted white and black line as a guide, we reposition the vertex back to its intended XY location:

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 while changing its elevation; drag the vertex along a golden dotted line to change its Z height.

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.
