Hello,
Is there anyway to move a created graphic point and get new coordinates ?
Regards

Here is a sample that allows you to draw and edit graphics.
Sketch temporary geometries | ArcGIS API for JavaScript 4.9
In this sample you can get the graphics new geometry in the updateGraphic function.

Hello Robert,
Is it possible to use the sketchviewmodel to edit data drawn by this code ?
Regards
