Hi Robert Scheitlin, GISP‌ / Experts,

I am trying to switch from 2D to 3D view and vice versa (followed the link Switch view from 2D to 3D | ArcGIS API for JavaScript 4.15 ) and facing some issues.

The layers are mainly oil pipelines, well pads, facilities, etc.

Each of the Feature Layer are added manually via FeatureService/0. Since the renderer is different for 2D and 3D, I need to be able to change the renderer to and re-render the map.

Snippet of code below:

var map = new Map({
        basemap: "topo-vector"
      });

      var switchButton = document.getElementById("switch-btn");

      var appConfig = {
        mapView: null,
        sceneView: null,
        activeView: null,
        container: "viewDiv",
        pipelineRenderer: null,
        wellpadRenderer: null,
        facilityRenderer: null
      };

      var initialViewParams = {
        zoom: 13,
        center: [-90.02620.745],
        container: appConfig.container,
        map: map
      };

      // create 2D view and and set active
      appConfig.mapView = createView(initialViewParams"2d");
      appConfig.activeView = appConfig.mapView;

      // create 3D view, won't initialize until container is set
      initialViewParams.container = null;
      appConfig.sceneView = createView(initialViewParams"3d");

      var view = appConfig.activeView;

      // Convenience function for creating a 2D or 3D view
      function createView(paramstype) {
        var view;
        var is2D = type === "2d";
        if (is2D) {
          view = new MapView(params);
          return view;
        } else {
          params.camera = {
            position: {
              x: -90.02,
              y: 20.745,
              z: 2000 // meters
            },
            tilt: 75
          };
          view = new SceneView(params);
        }
        return view;
      }
........
........
//Set inital Renderers
      appConfig.pipelineRenderer = pipelineRenderer;
      appConfig.wellpadRenderer = wellpadRenderer;
      appConfig.facilityRenderer = facilityRenderer;

      // Switch the view between 2D and 3D each time the button is clicked
      switchButton.addEventListener("click"function () {
        switchView();
      });

      // Switches the view from 2D to 3D and vice versa
      function switchView() {
        var is3D = appConfig.activeView.type === "3d";
        // var activeViewpoint = appConfig.activeView.viewpoint.clone();

        // Remove the reference to the container for the previous view
        appConfig.activeView.container = null;

        if (is3D) {
          // if the input view is a SceneView, set the viewpoint on the
          // mapView instance. Set the container on the mapView and flag
          // it as the active view
          // appConfig.mapView.viewpoint = activeViewpoint;
          // appConfig.mapView.container = appConfig.container;
          appConfig.activeView = appConfig.mapView;
          switchButton.value = "3D";
          appConfig.pipelineRenderer = pipelineRenderer;
          appConfig.wellpadRenderer = wellpadRenderer;
          appConfig.facilityRenderer = facilityRenderer;
        } else {
          // appConfig.sceneView.viewpoint = activeViewpoint;
          appConfig.sceneView.container = appConfig.container;
          appConfig.activeView = appConfig.sceneView;
          switchButton.value = "2D";

          // var pipeLineLayer = map.findLayerById("idPipelineLayer");
          // var facilityLayer = map.findLayerById("idFacilityLayer");
          // var wellpadLayer = map.findLayerById("idWellpadLayer");

          // pipeLineLayer.set(pipelineRenderer3D);
          // pipeLineLayer.refresh();

          // facilityLayer.set(facilityRenderer3D);
          // facilityLayer.refresh();

          // wellpadLayer.set(wellpadRenderer3D);
          // wellpadLayer.refresh();

          appConfig.pipelineRenderer = pipelineRenderer3D;
          appConfig.wellpadRenderer = wellpadRenderer3D;
          appConfig.facilityRenderer = facilityRenderer3D;
        }
      }

The issue is right when it calls the 

appConfig.activeView.container = null;

it starts throwing errors in the console as below:

and also below error on complete execution

And my 3D renderers don't come up.

NOTE:

  • Standalone my 3D layer renders perfectly fine as for my 2D, I am just trying to switch between them and vice versa.
  • Unfortunately I do not have a publicly available service for the layers to replicate the issue

Thanks in advance.

George,

   In this sample I do not have any issue with that.
