Having trouble extruding buildings in 3D

benjaminfriedman

Hello All, 

Having some trouble rendering my featureLayer in 3D. I just want to extrude these building footprints by the "HEIGHT" attribute in the data. 

Here is the code I am using: 

//******Create a UniqueValueRenderer*********
var buildingRender = {
type: "unique-value",
visualVariables: [{
type: "size",
field: "HEIGHT",
valueUnit: "feet"

}]
};

//******add a buildings layer************
var featureLayer = new FeatureLayer({
url: "https://services1.arcgis.com/oI9yEqRrROLp8e7v/arcgis/rest/services/NUSCArea/FeatureServer/0",
renderer: buildingRender
})

map.add(featureLayer);

This what happens: 

to this: 

I saw some talk of also having to vreate a polygon-3D renderer or something but I couldn't figure it out! 

Any help would be really appreciated. 

Thanks so much.
