Purpose

This module allows interactive measurement of distances in 2D whereas the distance is rendered in the 3D scene with a distance line (this a line with arrows) and the distance as number and unit synchronously.

Interaction in 2D goes through defining two points Start Pos and End Pos within the slices, whereas each of the points may be moved also.

Interaction

Consecutive clicks set the start and the end position.
