This node is basically used to measure and visually display arcLengths on
curves and surfaces at the specified point.
When dealing with curves, it measures the distance of the specified point
from the start point of the curve. On the other hand, when dealing with
surfaces, it measures the distance of the specified point from the start
point in both the u and v directions.
These nodes are created either using the "arcLengthDimension" command
or by using the "arc Length" tool. After creation, by using the "move"
tool, the shape can be moved around on the curve/surface, and the
arcLength values update interactively based on the new position of the
object.
