Runtime Geometry Engine vs. ArcGIS Core Geometry Engine

RodneyBunner

Hello,

I have an existing ArcObjects .NET stand alone application that I am converting to ArcGIS Runtime .NET.  In the ArcObjects application, I utilized many AO Geometry Engine methods such as  QueryPointAndDistance, QueryNormal, GetSubcurve and other methods which do not exist in the Runtime GeometryEngine.  A few questions related to this issue:

1.  Is there a native Runtime methodology to produce the same results as the methods listed above?

2.  If no to # 1, are there any plans to implement additional Runtime Geometry Engine methods such as those listed above? 

3.  If no to # 2, since the ArcGIS Core GeometryEngine contains the needed functions and the dll can be referenced in stand alone applications, does a methodology exist to convert Runtime Geometry objects to ArcGIS Core Geometry objects so that we can make use of the Core GeometryEngine functions?  

Thanks in advance,

Rodney

Thanks GeolTwinkle.  I did write my own GetSubcuve and QueryPointandDistance functions within Runtime to replicate the Core Geometry functions.  I haven't tested them extensively but they seem to work.  See below: 

public static void GetSubCurve(double fromDistance, double toDistance, Polyline inPolyline, ref Polyline outPolyline)
{

MapPoint nCreatepoint = GeometryEngine.CreatePointAlong(inPolyline, fromDistance);
MapPoint nCreatepoint2 = GeometryEngine.CreatePointAlong(inPolyline,toDistance);
List<MapPoint> mapPoints = new List<MapPoint>() { nCreatepoint, nCreatepoint2 };
PolylineBuilder pb = new PolylineBuilder(mapPoints);
Polyline nReshape = pb.ToGeometry();

Multipart nMP = GeometryEngine.Reshape(nReshape, inPolyline);
outPolyline = (Polyline)nMP;
}
public static void QueryPointandDistance(Polyline inPolyline, MapPoint inPoint, ref MapPoint outPoint, ref double distalong, ref double distFrom, ref bool bRight)
{
double dLength = GeometryEngine.Length(inPolyline);
double nFraction = GeometryEngine.FractionAlong(inPolyline, inPoint, -1);
distalong = dLength * nFraction;
outPoint = GeometryEngine.CreatePointAlong(inPolyline, distalong);
distFrom = outPoint.Distance(inPoint);

List<MapPoint> mapPoints = new List<MapPoint>() { inPoint, outPoint };
PolylineBuilder pb = new PolylineBuilder(mapPoints);
Polyline nReshape = pb.ToGeometry();
Geometry[] nGeom = GeometryEngine.Cut(nReshape, inPolyline);

if (nGeom is not null)
{ if (nGeom[0] is not null) bRight = false; }
{ if (nGeom[1] is not null) bRight = true; }
}
