The Edit functionality allows you to change your survey items. Enabling edit allows you to move existing, create new and delete existing vertices from your survey items. The Edit functionality only works on a single selected item and appears in the TOOLS tab.
Edit works on:
Info! Any edit can be undone using Ctrl+Z or the Undo button in the Quick Access Toolbar.
Moving existing vertices can be done in 3 different ways.
|On Terrain||Allows to change the position of a vertex using your mouse while keeping the vertex connected to the terrain.|
|XY||Allows to change the position of a vertex using your mouse while maintaining your elevation.|
|Z||Allows to change the elevation of one or multiple vertices using your mouse or the Z input field.|
You can also delete existing and create new vertices.
Select a vertex
Once you have enabled any of the available edit modes, you need to select a vertex first. The vertices will appear as white dots in edit mode. You can select them through a simple left-mouse click. A vertex will appear purple once it is selected. You can also select multiple vertices by pressing Ctrl. With Ctrl, each click on a vertex will add the vertex to the selection. In a similar way, you can select a range of vertices using Shift. In order to select all vertices, use Ctrl+A. You can move the selection to the next or previous vertex using the arrow keys.
Edit On Terrain
Selecting the On Terrain option will allow you to drag the vertex to a new location following the terrain.
When you are in the XY Edit mode, dragging a vertex will hold the elevation of the selected vertex while allowing the movement of the XY location. While keeping the left-mouse key selected, an orange helper plane appears and provides spatial context during the edit operation.
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. While keeping the left-mouse key selected, an orange helper line appears and provides spatial context during the edit operation. You can also enter a specific elevation for the vertex in the input field or use the spinners to change the elevation to the value you want.
Add a vertex
You can add a vertex to a polyline or a boundary by clicking on the segment between 2 existing vertices. Depending on the edit mode, the new vertex will fall straight down onto the terrain (On Terrain) or will be created at the elevation between the 2 existing vertices (linear interpolation).
Delete a vertex
Pressing the Delete key will delete the selected vertex and the selection moves automatically to the next vertex. This allows to quickly delete a sequence of vertices by pressing Delete multiple time. You can also select multiple vertices and delete them in one key stroke using Shift or Ctrl (see above). This delete operation is shown in the illustration below were a bulge (generated with Extract Level) is deleted to extract a correct water boundary.
