In the 3D view, it is possible to select scan points and then apply a variety of commands to this group of points.

Available Selection Tools in the 3D View

Click Selection in the Explore toolbar. The tools options toolbar is opened.

Select Polygon Button

The polygon selection applies to point clouds.

  1. Click the polygon tool.

  1. Click the left mouse button to define the starting point of the selection.

  2. Release the mouse button, move the mouse to the next point and click to fix the point.
    A straight connection is drawn automatically between these two points.
    You can also hold the mouse button down and drag the mouse over the area you want to select. Then all the scan points that you move over with the mouse are selected.

  1. Lock the selection by double-clicking with the left mouse button.

When completing the selection, the line will be closed; in other words, the last fixed point is connected to the starting point. The selection comprises all the scan points that are enclosed within the outline.

Select Brush Button

The brush selection can be used similar to brush tools known from 2D image processing programs. It works with scan point clouds or project point clouds.

The brush works in three-dimensional spaces, meaning that you can use the mouse to literally paint points which are going to be selected.

The brush has the shape of a sphere. A transparent red circle will highlight the area where the selection sphere is currently located.

  1. Click the left mouse button to define the starting point of the selection, hold the button down to paint the points.

  2. Moving the cursor around while having the brush selector tool activated will highlight the scan points that are currently within the selection sphere.

  3. Use the mouse wheel to modify the radius of the sphere.

  4. Hold the shift key to modify the sphere radius more quickly.
