BuildingComponentSublayers contain 3D Object features representing building components like doors, pipes or AC units. They are sublayers in a BuildingSceneLayer either directly or as part of a BuildingGroupSublayer. This sublayer is similar to a 3D Object SceneLayer, it can be visualized with a specific renderer, popups can be customized using popupTemplate and SQL filters can be applied by setting a definitionExpression.
Starting with version 4.17, BuildingComponentSublayers support attribute or spatial queries if the the BuildingSceneLayer has an associated feature layer.

Property Details
-
The name of the class. The declared class name is formatted as
esri.folder.className
.
-
definitionExpression String
-
The SQL where clause used to filter features on the client. Only the features that satisfy the definition expression are displayed in the View. Setting a definition expression is useful when only a subset of the data in the layer should be displayed.
Setting the definition expression of a layer automatically updates all layer views.
If the definition expression is set after the layer has been added to the map, the view will automatically refresh itself to display the features that satisfy the new definition expression.
Note that the initial loading time of the features remains unchanged, even if they are filtered. This happens because, as opposed to Feature Layers, feature filtering is done client-side. This means that all features need to be downloaded for filter evaluation.
This property is evaluated on the client using the cached attributes and it only supports standardized SQL.
-
The sublayer's layer id as defined by the Scene Service.
-
Indicates if this sublayer is empty. This property is only read from the service. Empty sublayers are not loaded for rendering and applications can choose to hide them in their UI.
-
listMode StringSince: ArcGIS Maps SDK for JavaScript 4.11
-
Indicates how the layer should display in the LayerList widget. The possible values are listed below.
Value Description show The layer is visible in the table of contents. hide The layer is hidden in the table of contents. Possible Values:"show"|"hide"
- Default Value:show
-
loadError Errorreadonly
-
The Error object returned if an error occurred while loading.
- Default Value:null
-
loadStatus Stringreadonly
-
Represents the status of a load operation.
Value Description not-loaded The object's resources have not loaded. loading The object's resources are currently loading. loaded The object's resources have loaded without errors. failed The object's resources failed to load. See loadError for more details. Possible Values:"not-loaded"|"loading"|"failed"|"loaded"
- Default Value:not-loaded
-
A list of warnings which occurred while loading.
-
The modelName is a standard name for each sublayer. For example the sublayer containing the doors in a building has the modelName "Doors". Use this property to retrieve sublayers in a BuildingSceneLayer.
Example// use modelName to identify a sublayer const doorslayer = buildingSceneLayer.allSublayers.find(function(sublayer) { return sublayer.modelName === "Doors"; });
-
Opacity of the sublayer.
- Default Value:1
-
Since: ArcGIS Maps SDK for JavaScript 4.12
-
An array of field names from the service to include with each feature. To fetch the values from all fields in the layer, use
["*"]
. Fields specified inoutFields
will be requested alongside with required fields for rendering.To include fields in all sublayers, use the outFields property of the parent layer.
- Default Value:null
-
popupEnabled Boolean
-
Indicates whether to display popups when features in the layer are clicked. The layer needs to have a popupTemplate to define what information should be displayed in the popup. Alternatively, a default popup template may be automatically used if Popup.defaultPopupTemplateEnabled is set to
true
.- Default Value:true
- See also
-
popupTemplate PopupTemplateautocast
-
The popup template for the sublayer. When set, the
popupTemplate
allows users to access attributes and display their values in the view's popup when a feature is selected using text and/or charts. See the PopupTemplate sample for an example of how PopupTemplate interacts with a FeatureLayer. Setting a PopupTemplate on this layer type is done in the same way as a FeatureLayer.A default popup template is automatically used if no
popupTemplate
has been defined when Popup.defaultPopupTemplateEnabled is set totrue
.- See also
-
The renderer assigned to the sublayer. The renderer defines how to visualize each feature in the sublayer. Depending on the renderer type, features may be visualized with the same symbol, or with varying symbols based on the values of provided attribute fields or functions.
Example// all features in the layer will be visualized with // a blue color sublayer.renderer = { type: "simple", // autocasts as new SimpleRenderer() symbol: { type: "mesh-3d", // autocasts as new MeshSymbol3D() symbolLayers: [{ type: "fill", // autocasts as new FillSymbol3DLayer() material: { color: "blue" } }] } };
-
type Stringreadonly
-
For BuildingComponentSublayer the type is always "building-component".
-
Indicates if the sublayer is visible in the view.
- Default Value:true

load(signal){Promise}
-
Loads the resources referenced by this class. This method automatically executes for a View and all of the resources it references in Map if the view is constructed with a map instance.
This method must be called by the developer when accessing a resource that will not be loaded in a View.
The
load()
method only triggers the loading of the resource the first time it is called. The subsequent calls return the same promise.It's possible to provide a
signal
to stop being interested into aLoadable
instance load status. When the signal is aborted, the instance does not stop its loading process, only cancelLoad can abort it.Parametersignal AbortSignaloptionalSignal object that can be used to abort the asynchronous task. The returned promise will be rejected with an Error named
AbortError
when an abort is signaled. See also AbortController for more information on how to construct a controller that can be used to deliver abort signals.ReturnsType Description Promise Resolves when the resources have loaded.
-
Since: ArcGIS Maps SDK for JavaScript 4.17

Executes a Query against the associated feature service and returns the 2D Extent of features that satisfy the query. At the moment the 3D Extent can be returned by using BuildingComponentSublayerView.queryExtent(), but this will return the 3D extent only for features currently in the view. The query succeeds only if the BuildingSceneLayer has an associated feature layer. If an associated feature layer is not available, then an error with the name
buildingscenelayer:query-not-available
is thrown. Read more about queries in the Querying section of the BuildingSceneLayer class description.Parametersoptional Autocasts from ObjectSpecifies the query parameters.
options ObjectoptionalAn object with the following properties.

when an abort is signaled. See also AbortController for more information on how to construct a controller that can be used to deliver abort signals.ReturnsType Description Promise<object> When resolved, returns the extent and count of the features that satisfy the input query. See the object specification table below for details. Property Type Description count Number The number of features that satisfy the input query. extent Extent The extent of the features that satisfy the query.

capability is enabled. Use the getFieldUsageInfo() method to check if the layer supports queries. If querying is not enabled, then an error with the namebuildingscenelayer:query-not-available
is thrown. Read more about queries in the Querying section of the BuildingSceneLayer class description.Parametersoptional Autocasts from ObjectSpecifies the query parameters.

removeHandles(groupKey)inheritedSince: ArcGIS Maps SDK for JavaScript 4.25
-
Removes a group of handles owned by the object.

when(callback, errback){Promise}
-
when()
may be leveraged once an instance of the class is created. This method takes two input parameters: acallback
function and anerrback
function. Thecallback
executes when the instance of the class loads. Theerrback
executes if the instance of the class fails to load.Parameterscallback FunctionoptionalThe function to call when the promise resolves.
errback FunctionoptionalThe function to execute when the promise fails.
ReturnsType Description Promise Returns a new promise for the result of callback
that may be used to chain additional functions.Example// Although this example uses MapView, any class instance that is a promise may use when() in the same way let view = new MapView(); view.when(function(){ // This function will execute once the promise is resolved }, function(error){ // This function will execute if the promise is rejected due to an error });
