ESM: import ExtrudeSymbol3DLayer from "@arcgis/core/symbols/ExtrudeSymbol3DLayer";
Class: esri/symbols/ExtrudeSymbol3DLayer
Inheritance: ExtrudeSymbol3DLayer Symbol3DLayer Accessor
Since: ArcGIS Maps SDK for JavaScript 4.0

ExtrudeSymbol3DLayer is used to render Polygon geometries by extruding them upward from the ground, creating a 3D volumetric object. This is done with a PolygonSymbol3D in a SceneView. MapView does not support 3D symbols.

The color of the symbol is set in the material property. The height of the extrusion is always defined in meters with the size property. Extrusion height and color can also be data-driven by adding size and/or color visual variables to any Renderer that uses this symbol layer.

An ExtrudeSymbol3DLayer must be added to the symbolLayers property of a PolygonSymbol3D. Multiple symbol layers may be used in a single symbol. The image below depicts a polygon FeatureLayer representing building footprints. The features are symbolized with a PolygonSymbol3D containing an ExtrudeSymbol3DLayer. The extrusion is based on the height of buildings.

Example
let symbol = {

  symbolLayers: [{
    type: "extrude",  // autocasts as new ExtrudeSymbol3DLayer()
    size: 100000,  // 100,000 meters in height
    material: { color: "red" }
  }]

Property Details

castShadows Boolean
Since: ArcGIS Maps SDK for JavaScript 4.11

Indicates whether the symbol layer geometry casts shadows in the scene. Setting this property to false will disable shadows for the symbol layer even if direct shadows are enabled in SceneView.environment.

Default Value:true
Example
// disables shadow casting
symbolLayer.castShadows = false;
declaredClass Stringreadonly inherited
Since: ArcGIS Maps SDK for JavaScript 4.7

The name of the class. The declared class name is formatted as esri.folder.className.

Since: ArcGIS Maps SDK for JavaScript 4.7

Sets the contour edges on polygons symbolized with ExtrudeSymbol3DLayer.

Example
let symbol = {
  type: "polygon-3d", // autocasts as new PolygonSymbol3D()
  symbolLayers: [{
    type: "extrude", // autocasts as new ExtrudeSymbol3DLayer()
    material: {
      color: [244, 247, 134]
    },
    edges: {
      type: "solid", // autocasts as new SolidEdges3D()
      color: [50, 50, 50, 0.5]
    }
  }]
};
material Objectautocast

The material used to shade the extrusion. This property defines the extrusion's color.

Property
color Color
optional
Default Value:white
Autocasts from Object|Number[]|String

The fill color of the extrusion. This can be autocast with an array of rgb(a) values, named string, hex string or an hsl(a) string, an object with r, g, b, and a properties, or a Color object.

Examples
// CSS color string
symbolLayer.material = {
  color: "dodgerblue"
};
// HEX string
symbolLayer.material = {
  color: "#33cc33";
}
// array of RGBA values
symbolLayer.material = {
  color: [51, 204, 51, 0.3];
}
// object with rgba properties
symbolLayer.material = {
  color: {
    r: 51,
    g: 51,
    b: 204,
    a: 0.7
  }
};
size Number

The height of the extrusion in meters. Negative values will extrude the polygon surface downward towards or below the ground.

Default Value:1
Example
// polygon is extruded 50,000 meters
symbolLayer.size = 50000;
type Stringreadonly

The symbol type.

For ExtrudeSymbol3DLayer the type is always "extrude".

Method Details

addHandles(handleOrHandles, groupKey)inherited
Since: ArcGIS Maps SDK for JavaScript 4.25

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

// Handle gets removed when the object is destroyed.
this.addHandles(handle);
Parameters
handleOrHandles WatchHandle|WatchHandle[]

Handles marked for removal once the object is destroyed.

groupKey *
optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

Creates a deep clone of the symbol layer.

Returns
Type Description
ExtrudeSymbol3DLayer A deep clone of the object that invoked this method.
Example
// Creates a deep clone of the graphic's first symbol layer
let symLyr = graphic.symbol.symbolLayers.getItemAt(0).clone();
fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter

A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns
Type Description
* Returns a new instance of this class.
hasHandles(groupKey){Boolean}inherited

A group key.

Returns
Type Description
Boolean Returns true if a named group of handles exist.

  obj.removeHandles("watch-view-updates");
}
removeHandles(groupKey)inherited
