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. You can enable the Edit Vertex feature in the TOOLS tab for any Point/Polyline/Boundary that is selected, and the Edit Vertex Mode box will appear.

Edit Vertex Modes

Editing existing vertices can be done in 5 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 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 circles 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. This is helpful in situations where you need to edit the vertices of a breakline to better fit the terrain, or when you've created a grid of points and some points are placed on top of objects instead of at ground level. You can simply move the point off of the object by using left-click and dragging the point over the terrain. You can also move multiple vertices at the same time.

Note: Geometry snapping will override the On Terrain edit mode if there is a drawn geometry near the area you are placing the vertex.

Move vertices to ground level using On Terrain in Edit Vertex Mode

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 plane 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 and keep the original elevation.

Move a vertex along the XY plane in Edit Vertex Mode

Note: Geometry snapping will override the XY edit mode if there is a drawn geometry near the area you are placing the vertex.

Edit Z

When you are in the Z Edit mode, you can manually enter a specific elevation for the vertex in the input field or use the arrows to change the elevation to the value you want.

Edit the Z elevation of two vertices by typing in the Z Coordinate in Edit Vertex Mode.

You can also drag a vertex into place. This will hold the XY position of the selected vertex while allowing the movement of the vertex in the Z direction. When dragging 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.

Edit the Z elevation of a vertex using the gold dotted line in Edit Vertex Mode.

Note: Geometry snapping will override the Z edit mode if there is a drawn geometry near the area you are placing the vertex.

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. This is often useful for overlapping stockpiles and you need to draw a boundary under the stockpile. To linearly interpolate the Z elevation between points, left-click on the first desired vertex, then left-click again on the last desired vertex—from the same polyline—to apply the interpolation

Place all vertices at the same elevation using Interpolate Z (Linear) in Edit Vertex Mode.

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. The Interpolate Z Curve is used for designing access or haul roads on a slope that gradually changes from the incoming and outgoing portion of the slope, which is necessary to allow trucks safe passage up and down the mine.

To apply a curve for a gradual slope on a design line, left-click on the first desired vertex, then left-click again on the last desired vertex—from the same polyline—to apply the interpolation to the design line. If there are grey starting and ending vertices, you will not be able to interpolate from those vertices. You need a long enough polyline that is drawn before and after the slope to create the gradual incoming and outgoing grade of the slope.

Create a gradual slope (or curve) of a polyline/boundary using Interpolate Z (Curve) in Edit Vertex Mode.

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.

Add a vertex with left click in Edit Vertex Mode.

Edit Mode for Adding a Vertex	Use Case
On Terrain	Most commonly used for a Survey
XY / Z	Used for Design
Interpolate Z (Linear and Curve)	Cannot add a vertex

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.

Delete a single vertex at a time using Delete on the keyboard or deleted multiple vertices b highlighting them with Shift + left click and pressing delete to remove a range of vertices.

Geometry Snapping with Edit Vertex

The Geometry Snapping feature helps you accurately connect existing geometry together. When moving a vertex using any of the Edit Vertex Modes, geometry snapping is enabled by default.

How Snapping Works

Geometry Snapping, when enabled, always takes preference over the Edit Vertex Mode's input setting (On Terrain, XY, and Z). E.g., if you've set the Edit Vertex Mode to On Terrain and there is a geometry near the vertex you are editing, a purple circle will appear, indicating that your vertex will first snap to the nearby polyline, rather than get placed on the ground.

Disable Snapping While Editing

Snapping is designed to streamline your workflow and create clean surfaces, but you can switch to free placement whenever necessary by disabling geometry snapping:

Deselect the Geometry snapping box with a left click.
Use the hot key "G" on the keyboard to toggle snapping on and off.
Press and hold Ctrl to temporarily disable snapping while moving a vertex over a geometry.

Snapping Suggestions

When editing a vertex, you'll see a projected guideline (white line), that creates a purple circle on each geometry in its path, indicating where your vertex will snap to that drawn polyline or boundary to align with your geometry's direction. You can also create your own snapping point on a geometry by hovering your cursor over a point on any drawn geometry until a purple circle appears. Simply left click when the purple circle appears to snap to that existing vertex or geometry.

Geometry Snapping basics just using left click to move a vertex.

Use Tab for Stacked Geometries. If you have stacked geometries, there will be multiple suggestions available that you can snap your vertices to, including the terrain itself. To choose which suggestion to snap to:

Left click and hold the vertex to drag it over the area you want to snap to.
Press Tab to see a small box of options appear, then repeatedly press Tab to cycle through each suggestion.
Once the location you want to place your vertex is highlighted, release left click to place your vertex.

Extend or Trim a Line

In a situation where your line is drawn too long or too short, you can maintain the direction of that line and either extend or reduce the length as desired. You can also extend or reduce the length of the line to snap to an adjacent line with ease. When you edit the end vertex of a line, a white guideline will appear showing you the direction the line is heading. You can then use the snapping feature to attach it to any adjacent lines in the direct path of the line. The white guideline only appears when editing the end vertices of a line, and the guide will show a purple circle you can snap to on any adjacent lines in the guideline's path.

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 and keeps the vertices in the same relative position compared to each other.
- 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
- Allows you to make a specific elevation offset that moves the entire drawing as a complete geometry on the Z axis and keeps all vertices in the same XY positions 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.
