esri/widgets/BuildingExplorer
The BuildingExplorer widget is used to filter and explore the various components of BuildingSceneLayers. BuildingSceneLayers are complex digital models of buildings and interiors and can contain thousands of components grouped in sublayers. Using this widget, buildings can be filtered by level, construction phase or by disciplines and categories. Three elements are used to filter BuildingSceneLayers: the Level element, the Construction phases element and the Disciplines are Categories list. The visibility of these elements can be configured using the widget's visibleElements.
The BuildingSceneLayers to be explored have to be set on the layers property of the widget. When setting multiple layers, the filters set by the widget will be applied on all layers. The widget doesn't allow the user to select between multiple BuildingSceneLayers in a SceneView.
Often, BuildingSceneLayers contain an overview BuildingComponentSublayer that serves as an exterior shell and views the building model as a single feature. When a layer is added to the BuildingExplorer widget, the visibility of the overview layer is turned off, so that the user can interact with the individual features in the full model BuildingGroupSublayer.
The Level element of the BuildingExplorer widget allows to select a single level in one or several buildings. When selecting a level, the levels above it are hidden and the levels below it become semi-transparent for added visual context.
Some BuildingSceneLayers include information indicating the phase when the components were created, and optionally, when they were demolished. If a layer has multiple construction phases, these will be displayed in the Construction phases element. When selecting a construction phase, all the components created during or before the phase are selected. Demolished components aren't displayed.
Discipline layers are group layers that organize the BuildingSceneLayer content into architectural, structural, mechanical, or electrical groups. These layers contain a number of Category layers such as walls, windows, furniture, and lighting fixtures. These layers can be turned on and off in the Disciplines and Categories list.
The widget can only display filters set by the widget itself. Filters set by other applications will be ignored.
const buildingExplorer = new BuildingExplorer({
view: view,
layers: [buildingSceneLayer]
});
// adds the BuildingExplorer to the top right corner of the SceneView
view.ui.add(buildingExplorer, "top-right");

container
InheritedPropertycontainer String |HTMLElement
Inherited from Widget -
The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use case when working with widgets.
Examples// Create the HTML div element programmatically at runtime and set to the widget's container const basemapGallery = new BasemapGallery({ view: view, container: document.createElement("div") }); // Add the widget to the top-right corner of the view view.ui.add(basemapGallery, { position: "top-right" });
// Specify an already-defined HTML div element in the widget's container const basemapGallery = new BasemapGallery({ view: view, container: basemapGalleryDiv }); // Add the widget to the top-right corner of the view view.ui.add(basemapGallery, { position: "top-right" }); // HTML markup <body> <div id="viewDiv"></div> <div id="basemapGalleryDiv"></div> </body>
// Specify the widget while adding to the view's UI const basemapGallery = new BasemapGallery({ view: view }); // Add the widget to the top-right corner of the view view.ui.add(basemapGallery, { position: "top-right" });
-
headingLevel
headingLevel Number
Since: ArcGIS Maps SDK for JavaScript 4.20BuildingExplorer since 4.16, headingLevel added at 4.20. -
Indicates the heading level to use for the headings in the widget. By default, they are rendered as level 3 headings (e.g.
<h3>Disciplines & categories</h3>
). Depending on the widget's placement in your app, you may need to adjust this heading for proper semantics. This is important for meeting accessibility standards.- Default Value:3
- See also
ExamplebuildingExplorer.headingLevel = 4;
-
icon
icon String
Since: ArcGIS Maps SDK for JavaScript 4.27BuildingExplorer since 4.16, icon added at 4.27. -
Icon which represents the widget. It is typically used when the widget is controlled by another one (e.g. in the Expand widget).
- Default Value:"organization"
- See also
-
label
label String
-
The widget's default label.
-
layers
layers Collection<BuildingSceneLayer>
-
A collection of layers of type BuildingSceneLayer that are added to the widget for exploration. The widget is only displayed when this property is set. In case of multiple layers, the widget will display and apply the filters on all layers.
-
viewModel
viewModel BuildingExplorerViewModelautocast
-
The view model for this widget. This is a class that contains all the logic (properties and methods) that controls this widget's behavior. See the BuildingExplorerViewModel class to access all properties and methods on the widget.
-
visible
InheritedPropertyvisible Boolean
Inherited from Widget -
Indicates whether the widget is visible.
If
false
, the widget will no longer be rendered in the web document. This may affect the layout of other elements or widgets in the document. For example, if this widget is the first of three widgets associated to the upper right hand corner of the view UI, then the other widgets will reposition when this widget is made invisible. For more information, refer to the css display value of"none"
.- Default Value:true
Example// Hides the widget in the view widget.visible = false;
-
visibleElements
visibleElements VisibleElements
-
This property provides the ability to display or hide the individual elements of the widget. BuildingExplorer has three elements: buildings levels filter, construction phases filter and the sublayers list. By default they are all displayed. In case the BuildingSceneLayer doesn't provide field statistics information, then the filters for building levels and construction phases will not be displayed.
Example// only display the building levels filter buildingExplorer.visibleElements = { phases: false, disciplines: false };
