Maybe you can try other simple tools. With GISBox, you can easily generate a 3D tile layer based on the map in just a few steps.

After creating a new scene, find "Get Map Data" in the menu bar.

Click here to check the Image1

In the window, you can enter the maximum and minimum longitude and latitude coordinates to determine the map range, or you can use the mouse to select a box in the map.

Click here to check the Image2

In this way, the corresponding 3D tile layers will be generated in the scene.

Here is San Francisco area 3d tile map with ArcGISTiledElevationTerrainProvider()

Example code copied from Cesium demo link And replace url of Indexed 3D Scene (I3S) layer

From

https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/SanFrancisco_3DObjects_1_7/SceneServer/layers/0

https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/SanFrancisco_Bldgs/SceneServer?cacheKey=90e21aeb68997279

I got from arcgis San Francisco 3D Buildings service in here

And arcgis map (Scene Service Viewer)

https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/SanFrancisco_Bldgs/SceneServer?view=sceneview&f=html&cacheKey=90e21aeb68997279

        // Create I3S data provider
        const i3sProvider = new Cesium.I3SDataProvider(i3sOptions);

        // Center camera on I3S once it's loaded
