Using the Data Slice Control

After creating a point cloud model, you can designate which section(s) of it to include using the Data Slice Control. This control enables you to define either exclusion or inclusion bounding boxes. 

§  Inclusion box – Only points inside the box are displayed.

§  Exclusion box - Only points outside the box are displayed.

When the point cloud model is selected for editing, a yellow frame and a red frame surround it. The yellow frame represents the total area of the point cloud model. The red frame represents the area that will be displayed. When you use the sliders on the Data Slice Control, the red frame is updated to show the selected area.
