Add WebStyleSymbol into graphicslayer

TubaKumbara — Tue, 10 Apr 2018 09:38:45 GMT

Hello.

var webStyleSymbol = new WebStyleSymbol({
name: "Ambulance",
styleName: "EsriRealisticTransportationStyle"
});

I want to add a 3D ambulance icon into a graphicslayer.

I'm facing "Failed to create symbol from style" error.

I tried some codes but failed always. Can anyone help me please?

Tuba,

You are attempting to use this in a WebScene right? Also you can utilize the APIs autocasting by using:

// Referencing a web style via styleName
var webStyleSymbol = {
  type: "web-style",  // autocasts as new WebStyleSymbol()
  styleName: "EsriRealisticTransportationStyle",
  name: "Ambulance"
};‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks for the answer. Yes in sceneview, But i don't know what i'm doing wrong

I want to add this symbol into clicked mouse position and clicked elevation height

here is my code,

on map mouse click event

var point = {
type= "point",
x: e.mapPoint.longitude,
y: e.mapPoint.latitude,
z: myHeight // came from elevation query
}
var webStyleSymbol = {
type: "web-style", // autocasts as new WebStyleSymbol()
styleName: "EsriRealisticTransportationStyle",
name: "Ambulance"
};
var gr = new Graphic {
geometry: point,
symbol: webStyleSymbol
}
myGraphicsLayer.graphics.add(gr);

But i see nothing

Tuba,

Here is a sample where I add a ambulance to a Graphics layer based on hard coded coordinates:

Thanks for helpfull code Robert.

I copied your whole sample code and paste it into a html document.

I tried on 2 different machines (no internet access) but i'm still getting error.

Failed to load https://www.arcgis.com/sharing/rest/portals/self?f=json&culture=tr-tr: The 'Access-Control-Allow-Origin' header has a value 'null' that is not equal to the supplied origin. Origin 'null' is therefore not allowed access.
[esri.symbols.WebStyleSymbol] #fetchSymbol() Failed to create symbol from style

I have no internet access on my computers.

I tried your sample code on JSFIDDLE. This is working good.

Esri JS API 4.6 TEMPLATE - JSFiddle

is web-style-symbols need to internet connection?

Tuba,

As far as I know YES they do.

I think that we should be able to add webstylesymbol without internet connection.

Hello, thank you for the sample code! It helped me a lot.

However, the following parameters seem to have no effect:

attributes: { ObjectID: 0, SIZE: 12, ROTATION: 100 }

No matter how I set the ROTATION parameter, the model always points to the north. I would like to ask if it is possible to rotate the model? Thank you!
