The Measurement widget in 3D apps allows you to measure horizontal, vertical, and direct distance between two points.
In a WGS84 or Web Mercator scene, when the distance between the points is greater than 100 kilometers, the Measurement widget switches to displaying only the horizontal and vertical distances, taking into consideration the curvature of the earth (that is, ellipsoid-based geodesic distance).
Configure the Measurement widget
This widget can be set to open automatically when an app starts. To enable this feature, click the Open this widget automatically when the app starts button on the widget, which turns it dark green.

Use the Measurement widget
Click the Measurement widget icon to open it. When the widget is active, you need to click the New Measure button to enable the measurement tool. After clicking New Measure button, click a location on the map and start to move your pointer. A horizontal laser line is drawn to indicate the height at the current mouse position. This line can help in analyzing the heights of objects relative to each other and the terrain. A second laser line shows the intersection of the scene with the vertical plane that passes through the checkered line. The widget labels the direct, horizontal, and vertical orange distance lines and displays the same values in the UI panel. You can always start a new measure by clicking the New Measure button on the widget. .
