Coordinate conversion in SketchViewModel

[ararana]

Looking at the Sketch in 3D example code, in the sketchViewModel.on("create" function a new line's point coordinates are coming across in a unusual format

Can anyone explain what this coordinate format is and how I could convert it to standard longitude/latitude?

I think default coordinate system for esri maps is in webmercator format. you should use webMercatorUtils' webMercatorToGeographic() to convert to geo coordinates: https://developers.arcgis.com/javascript/latest/api-reference/esri-geometry-support-webMercatorUtils...

Was not aware of the webMercatorUtils class. Thanks for the help!
