Property Overview

Property Details

declaredClassStringreadonly

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

materialObject

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

Property:

color Color optional The fill color of the extrusion. This can be autocast with a named string, hex string, array of rgb or rgba values, an object with r, g, b, and a properties, or a Color object. Default value: white

Examples:

// CSS color string

  color: "dodgerblue"
};

// HEX string
symbolLayer.material = {
  color: "#33cc33";
}

// array of RGBA values
symbolLayer.material = {
  color: [51, 204, 51, 0.3];
}

// object with rgba properties

  color: {
    r: 51,
    g: 51,
    b: 204,
    a: 0.7
  }
};

sizeNumber

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

Default Value: 1

Examples:

// polygon is extruded 50,000 meters
symbolLayer.size = 50000;

// polygon is extruded 50,000 meters below the ground
symbolLayer.size = -50000;

typeStringreadonly

For ExtrudeSymbol3DLayer the type is always extrude.

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.

toJSON(){Object}inherited

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