I would like to do some custom edit operation: editing a circle.
I am using a Polyline as the editing geometry to render its centerPoint to a pointOnCircumference. User can drag either of the point to edit the the circle.
However observed that when I tapped somewhere in the middle of the polyline, a point is added. Couldn't find any edit configuration that disables adding of a vertex, even if I set the feedback mid vertex to invisible display.
Any advice? Thanks in advance!
