I am using the SketchViewModel to draw a graphic. When I draw the polygon as self intersecting, most of the time, the isSelfIntersecting property on the geometry comes back as false. Sometimes, but infrequently, the same shape comes back as true. Is this a bug? Any other way to determine self intersection?
Also, I am not sure why there are two arrays for the rings array. Any thoughts on this?
This is using the Esri JavaScript API 4.11
I am also experiencing this bug.
Do you have a very simple codepen showing the issue?
If you follow the vertices around in order you'll notice that they geometry does not self-intersect. Here's a codepen where we number the vertices so you can understand why this geometry doesn't self-intersect: https://codepen.io/john-grayson/pen/gOmaObZ
