PolygonSymbol3D

PolygonSymbol3D is used to render features with Polygon geometry in a 3D SceneView. This symbol type is not supported in 2D MapViews. Polygon features may also be rendered as points with icons or objects at the centroid of each polygon.

A PolygonSymbol3D must include at least one symbol layer for it to render in the view. One or more of the following symbol layer types must be used to define a 3D polygon symbol:

Symbol3DLayer Type	Flat/Volumetric	Size Units	Example
FillSymbol3DLayer	flat	-
ExtrudeSymbol3DLayer	volumetric	meters
WaterSymbol3DLayer	flat	-
LineSymbol3DLayer	flat	points
IconSymbol3DLayer	flat	points
ObjectSymbol3DLayer	volumetric	meters
TextSymbol3DLayer	flat	points

See Symbol3DLayer and Symbol3D to read more general information about 3D symbols, symbol layers and how they relate to one another.

Example

let symbol = {
  type: "polygon-3d",  // autocasts as new PolygonSymbol3D()
  symbolLayers: [{
    type: "extrude",   // autocasts as new ExtrudeSymbol3DLayer()
    size: 1000,        // Height of the extrusion in meters
    material: { color: "blue" }
  }]
};

Constructors

new PolygonSymbol3D(properties)

Parameter

properties Object optional See the properties for a list of all the properties that may be passed into the constructor.

Property Overview

Property Details

declaredClass Stringreadonly inherited

Since: ArcGIS API for JavaScript 4.7

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

styleOrigin StyleOrigin inherited

The origin of the style from which the symbol was originally referenced. A reference to the style origin can be either by styleName or by styleUrl (but not both). This information is part of the WebScene persistence model and may be used to understand where a symbol was originally sourced from. It does not affect actual appearance or rendering of the symbol.

symbolLayers Collection<(ExtrudeSymbol3DLayer|FillSymbol3DLayer|IconSymbol3DLayer|LineSymbol3DLayer|ObjectSymbol3DLayer|TextSymbol3DLayer|WaterSymbol3DLayer)>autocast

Autocasts from Object[]

A Collection of Symbol3DLayer objects used to visualize the graphic or feature. Individual symbol layers may be autocast as objects and specified using the type property.

type Stringreadonly

The symbol type.

For PolygonSymbol3D the type is always "polygon-3d".

Method Overview

Method Details

addHandles(handleOrHandles, groupKey)inherited

Since: ArcGIS API 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.

clone(){PolygonSymbol3D}

Creates a deep clone of the symbol.

Returns

Type	Description
PolygonSymbol3D	A deep clone of the object that invoked this method.

Example

// Creates a deep clone of the graphic's symbol
const symbolLayer = graphic.symbol.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

json Object 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

Since: ArcGIS API for JavaScript 4.25

Returns true if a named group of handles exist.

Parameter

groupKey * optional A group key.

Returns

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

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles(groupKey)inherited

Since: ArcGIS API for JavaScript 4.25

Removes a group of handles owned by the object.

Parameter

groupKey * optional A group key or an array or collection of group keys to remove.

Example

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");

toJSON(){Object}inherited

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns

Type	Description
Object	The ArcGIS portal JSON representation of an instance of this class.
