You want to edit your survey when you have misplaced a vertex or a polyline or when you want to align an existing survey onto a recently acquired terrain so that you don't need to redo your entire line work.
When you are in sketch mode, you can undo your last vertex or line segment.
Once your survey object is created you can:
- Edit a vertex
- Shift a survey object
- Delete a survey object, or
- Delete a group of survey objects that are contained within a polygon by Area Delete.
Undo last vertex
When you are in sketch mode you can remove the last drawn vertex by clicking Backspace. Each time you click Backspace the last placed vertex will be removed.
When you are using the Guided Breakline Drawing function, you can also remove entire line segments by clicking Ctrl+Backspace.
Edit a vertex
The vertices of the selected feature will appear as white dots. Hover your mouse over a vertex in the 3D window and when it becomes highlighted you can move the vertex to the required location. While moving, your vertex will continue to follow the terrain.
Vertices of each other object you select can be edited until you exit the edit mode. To do this, click on the Vertex button one more time (or click Alt+V).
Shift a feature
Select the object which you want to shift first by clicking on the object in the 3D viewport or the ProjectTree. Then toggle the Shift button (or use the shortcut Alt+H).
The selected feature will become highlighted with a yellow rectangle. Afterwards move the feature to the required location using the mouse. While moving, your point, polyline or polygon vertices will continue to follow the terrain.
Select the object which you want to delete first by clicking on the object in the 3D viewport or the ProjectTree. Then press Delete and the object will be removed.
When the button is enabled, click in the 3D window to draw a polygon around the area of interest.
Complete the drawing with a right mouse click.
- Click Yes in the pop-up window. This will remove all features that are completely or partly located within the area you defined.
