Hi,
I have an application where user can edit polygon geometries by drawing a polyline. The tool works fine most of the time but sometimes the users are able to draw a polyline that gives the following exception when used to reshape a polygon:
{System.Exception: Out of range :
at RuntimeCoreNet.Interop.HandleException(Boolean retVal)
at RuntimeCoreNet.CoreGeometryEngine.Reshape(ICoreGeometry geometry, CorePolyline reshaper, CoreSpatialReference sr)
at Esri.ArcGISRuntime.Geometry.GeometryEngine.Reshape(Geometry geometry, Polyline reshaper)
at ArcGISRuntime.Samples.DesktopViewer.MainWindow.ReshapeGeometry()}
HResult = -2146233088
Currently I just handle the exception and notify the user but I was wondering what actually is causing that error because the application would accept the edit otherwise. I was able to reproduce this easily with following code:
private void ReshapeGeometry()
{
var segment = new LineSegment(571528.331418344, 7015935.19781517, 571522.829343446, 7015932.7313678);
var segment1 = new LineSegment(571522.829343446, 7015932.7313678, 571526.821556906, 7015958.60602131);
var segment2 = new LineSegment(571526.821556906, 7015958.60602131, 571539.179356696, 7015958.48119505);
