Hi Matthias, The input polyline should be known simple before calling Cut. You can do this by calling either GeometryEngine.Instance.IsSimpleAsFeature (if you know that it is simple) or GeometryEngine.Instance.SimplifyAsFeature (if you're not sure if it is simple or not).  For future reference, if a GeometryEngine method throws a GeometryObjectException with the message "GeometryObjectException: The operation cannot be performed on a non-simple geometry.", then the geometry needs to be known simple. The doc should explicitly mention this, so we will update it. Thank you for pointing it out.  Let me know if you have any questions. Annette ... View more

In the meantime, you could insert the geometries into a feature class in a geodatabase and use the GeoProcessing tool CheckGeometry.  https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/check-geometry.htm ... View more

Hi Kirk, The Pro SDK doesn't have it, but we do have an issue in our queue to add it. I will update the priority to include it in an upcoming release. Thanks, Annette ... View more

Hi Kris, The domain extent is different than the valid area of a coordinate system. The domain extent is an arbitrary square used to delimit valid coordinates for a spatial reference system and determine their resolution. It is possible that the domain extent is larger than the usable area of a coordinate system (a UTM zone, for example). I suspect that what you are looking for is the horizon. We plan to add a method to get the horizon in a near-term release. In the meantime, you can take a look at https://community.esri.com/message/935357-re-how-to-get-the-spatialreference-horizon-polygon  for a possible workaround.  I hope that helps.  Thanks, Annette ...

Alan, You are right. This won't work for the reason that you stated. We will add a method to get the horizon from the spatial reference in a near-term release.  Thank you, Annette ... View more

Hi Alan, I will take a look and get back to you.  Thanks, Annette ... View more

I forwarded your question to our 3D team. Here is their answer: It looks like they want to see where ‘view frustums’ from airborne imaging devices intersect the ground. We don’t have a ‘IntersectMultipatchWithSurface’ tool but we do have ‘Intersect3DLineWithSurface’. If the user models the 4 corners of a view frustum, or its center, as 3D polyline features, they can get back the points of intersection between the lines and the surface. ... View more

If the geometries are disjoint, then an empty geometry will be returned. Can you share your data? ... View more

Hi Sai, A spatial reference is not required for most of the GeometryEngine methods. For the Project and geodesic methods, you must have a spatial reference defined. The other methods use the tolerance of the spatial reference to determine if points that are close to each other should be considered equal. If you don't have a spatial reference defined, then a default tolerance is used.  When you say that you tried GeometryEngine.Intersection with geometries that don't have a spatial reference, what do you mean that it yielded no results? Did it return an empty geometry, a null geometry, or throw an exception? It should work. Annette ... View more

Hi, When you say it returns a GCS instead of a transformation, how are you trying to retrieve it? Annette ... View more

Hi Fayu, We will add a setter for the Domain property in the next release. In the meantime, you can change the xy-scale which will change the domain.  Here is an example: const long suLimit = 9007199254740990; // Default domain for Web Mercator is xmin = -20037700, // ymin = -30241100, xmax = 900699887774.099, ymax = 900689684374.099 // with xyScale = 10000 // To change the domain change the xyScale. This will keep the same false origin, // but xmax and ymax will change. // Make the xyScale smaller => xmax, ymax are bigger. // xyScale bigger => xmax, ymax are smaller. SpatialReferenceBuilder builder = new SpatialReferenceBuilder(SpatialReferences.WebMercator); // Suppose I know what I want my domain to be, then I have to figure out the scale. // xyScale = suLimit / (xmax - xmin) // assuming that xmax - xmin = ymax - ymin i.e. domain is a square. // If xmax - xmin != ymax - ymin, take the larger of the two. // Expand the default domain double xMin = -20037700; double xMax = 9007179217040.99; double yMin = -30241100; double yMax = 9007169013640.99; double xyScale = suLimit / Math.Max(xMax - xMin, yMax - yMin); // xyScale = 1000 builder.XYScale = xyScale; Envelope domain = builder.Domain; Console.Out.WriteLine($"xMin = {domain.XMin}"); Console.Out.WriteLine($"xMax = {domain.XMax}"); Console.Out.WriteLine($"yMin = {domain.YMin}"); Console.Out.WriteLine($"yMax = {domain.YMax}");‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Let me know if you have any questions.
