Is there a simple way to use GeometryEngine.Instance.QueryPoint to get a point a specified distance from the end of the line? It seems to default to the start of the line??
Or do I just need to add some math logic to my code??
Yes you can simply reverse the orientation of your line geometry and do the querypoint using the original distance.
var reverseGeom = GeometryEngine.Instance.ReverseOrientation(geometry as Multipart); var qPoint = GeometryEngine.Instance.QueryPoint(reverseGeom, SegmentExtension.NoExtension, dac, AsRatioOrLength.AsLength);
or alternatively get the length of the geometry and work out the new query point distance.
var length2D = GeometryEngine.Instance.Length(geometry); var newDistance = length2D - originalDistance; var qPoint = GeometryEngine.Instance.QueryPoint(geometry, SegmentExtension.NoExtension, newDistance, AsRatioOrLength.AsLength);
Hi Sean Jones. I ended up just doing math on it, but it's good to know about the ReverseOrientation option.
