Returns a
Polyline instance representing the current state of the builder.
Reverse the order of points in a Polyline
var polylineBuilder = new PolylineBuilderEx(polyline);
polylineBuilder.ReverseOrientation();
Polyline reversedPolyline = polylineBuilder.ToGeometry();
Build a multi-part Polyline

// use AttributeFlags.None since we have 2D points in the list
