Fence tool

Menu: Edit / Fence


Instead of creating an extraction, it's possible to isolate points while staying in the main point cloud by using a fence. When no fences exist yet in the project, the fence tool will automatically start in picking mode, else the button "Pick" must be selected to generate a new fence. When picking a fence, a closed polygon is created in the same way as with the select tool: begin the fence by clicking the left mouse button around the desired area. Clicking on the right mouse button will close the polygon.

A number of options are available:

  • Pick: Begins the picking process for picking a fence on screen
  • Apply: Reapplies an existing fence
  • Draw: Displays the existing fence on screen
  • Erase: Erases the existing fence from the screen
  • Hide out: Hides all points outside of the fence
  • Hide in: Hides all points inside the fence


The active fence can be drawn or erased. The fence is a 2D shape that is not part of the point cloud - filtered points are therefore any points inside/outside the fence when the fence was applied. If the user navigates in the point cloud, the fence will stay the same on screen (if it was drawn). Displacing the main window and clicking on “Apply” will recreate the fence around a new set of points.
Note that the fence can not be activated with the bounding box simultaneously, generating a fence will deactivate the bounding box and vice-versa.
