I have an ESRI map service that exposes polylines. This map service has HasZ: true.
The z-value is relative to the sea level, not to the terrain.
When I add this map service to a map and display it in a SceneView, I have the impression that the geometries are draped on the basemap and that their true z-values are ignored.
The map service has Spatial Reference: 31370.
Is it possible to display true 3D geometries in the SceneView?
