Hello, guys!
While I want to use the "esri.geometry.geometryEngineAsync"( added at v3.13) in arcgis API for javascrip with Legacy coding style, I have a problem how to instance an object to use it. Where there is no constructor method for geometryEngineAsync or geometryEngine.
I've added "dojo.require("esri.geometry.geometryEngineAsync");" in the head of the file.
Thanks a lot!
