Symbol layers are used to define the visualization of Point, Polyline, Polygon, and mesh geometries rendered with 3D symbols. 3D symbols may only be used to render features in a FeatureLayer, SceneLayer, or standalone graphics in a 3D SceneView. There is no support for 3D symbols in 2D MapViews.
All 3D symbols have a symbolLayers property, which is an array of Symbol3DLayer objects. All symbols must have at least one symbol layer added to the
symbolLayers property. Think of the symbol object as a container that holds multiple symbol layers which define the appearance of the symbol. One layer may be an outline, another the fill, etc. The relationship of symbol layers to symbol is similar to the relationship of operational layers to a Map.
|Symbol3DLayer Type||Symbol3D Type||Flat/Volumetric||Size Units||Example|
|TextSymbol3DLayer||PointSymbol3D, LineSymbol3D, PolygonSymbol3D, LabelSymbol3D||flat||points|
Each symbol layer has a material property that defines the color of the symbol.
The size of all flat symbol layers is defined in either points or pixels (screen space) whereas the size of all volumetric symbol layers is defined in meters (real-world space).

Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform.more details
Converts an instance of this class to its ArcGIS Portal JSON representation.more details
Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform. The object passed into the input
jsonparameter 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.
