==== Concepts ====

A slice represents a 2D representation of a chosen area from a 3D point cloud based on a defined plane. It can be a horizontal, vertical or user defined angular plane.

==== Navigation ====
Navigation in the Slice Viewer window is similar to navigation on 3D Map, see: [[112:orbit_desktop:map:3d|]]



==== Slice View Tab ====

 **Vertical**\\
Defines the vertical plane of the slice by clicking for the origin and end positions on the 3D Map

**Horizontal**\\
Defines the horizontal plane of the slice by clicking on a location on the 3D MAP

 **Other**\\
Defines a plane with a custom angle defined by three clicks: the origin, and the orientation

 **Measure**\\
Starts the measurement. On the Slice Viewer, the measurements are represented by construction points, that have a correspondent in vertexes on the 3D Map, acording to the selected tool in Map 3D Measurements window.

**Clear**\\
Deletes the slice.

 **Stop Measure**\\
Finalizes the measurement. The construction points are deleted when stopping the measurement. 

 **Clip**\\

 **Slice Position**\\
By adjusting the slider it is possible to adjust the position of the slice in the 3D Map. This will modify the position of measurements.

 **Slice Thickness**\\
By adjusting the slider it is possible to modify the thickness of the slice. This will modify the in turn the number of  points taken into account when measuring.


==== Measure functions ====

All the measuring functions available in the Map 3D Measurements window can be used in the Slice Viewer

==== How to measure ====

  * Define your slice according to your needs (choose the plane type) 
  * Point the location of your slice
  * Adjust the position and thickness
  * Choose the measuring tool you want
  * Press Measure
  * Click on the desired location on the Slice Viewer
  * Stop Measure when the object is completly measured


==== Results==== 

This tool is very useful for taking measurements in places where there are no points in the pointcloud. For example, to measure exactly the center of tree's bark, where no points are present. In this way we can create new objects with more accurate position.

The measurements can be saved as objects by using the Copy to Feature function on the measurements window, see: [[112:mobile_mapping:desktop:feature_extraction:index|]]
