This tool computes the distance between two point clouds, or the distance between two sets of point classes within the same cloud. The computed distance is input into the points' **Distance** attribute (visible in the cloud visualization panel).

In the example below, Unclassified (01) points have their distance computed in respect to the Transmission Wire (14) class:
