Hi,
I have been searching online on using ArcGIS JavaScript API to create and visualize droplines and trail lines based on the movement of 3D models in JavaScript web application.
However, i am unable to find any relevant results.
Appreciate advice on how to create and visualize droplines and trail lines based on the movement of 3D models in ArcGIS JavaScript.
An example of dropline and trail line are illustrated as the red lines in the following picture.

Many Thanks.
Ben
