Can not create a 3D-features(have z value) using a geoprocessing package executed with Local Server

AlexanderZhang

Hi,all

    I created a geoprocessing package (.gpkx) in ArcGIS Pro(3.02) involving a custom geoprocessing model that includes the Interpolate Shape (3D Analyst)  geoprocessing tool, which output a poyline 3D feature with z-value,  i executed the geoprocessing package with ArcGIS Runtime Local Server(200.1) using ArcGIS Maps SDK for .Net(200.2) , i got the poyline feature from the output, but the polyline feature is not has a z-value, and the z-values of the points("_Result") on the poyline are all 0.Can someone help me? thanks, 

  The relevant code is as follows:

 

private async void GpJobOnJobChanged(object o, JobStatus e)
        {
            // Show message if job failed
            if (_gpJob.Status == JobStatus.Failed)
            {
                 MessageBox.Show("Not found reason!", "Job Failed");
                return;
            }

            // Return if not succeeded
            if (_gpJob.Status != JobStatus.Succeeded) { return; }

            try
            {
                // Get the results from the outputs.
                GeoprocessingResult result = await _gpJob.GetResultAsync();

                var value = result.Outputs.Values.LastOrDefault() as GeoprocessingFeatures;

                IFeatureSet? gpOutputFeatures = null;

                if (value.CanGetOutputFeatures)
                    gpOutputFeatures = await value.GetOutputFeaturesAsync();
                else
                    gpOutputFeatures = value.Features ;

                List<MapPoint> mapPoints = new List<MapPoint>();

                foreach (var feature in gpOutputFeatures)
                {
                    if (feature.Geometry is Esri.ArcGISRuntime.Geometry.Polyline polyline)
                    {
                        foreach (var part in polyline.Parts)
                        {
                            mapPoints.AddRange(part.Points);
                        }
                    }
                }
                _Result = mapPoints;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "Error");
            }
            finally
            {
                // Remove the event handlers.
                _gpJob.ProgressChanged -= GpJob_ProgressChanged;
                _gpJob.StatusChanged -= GpJobOnJobChanged;
            }

        }

Thank you @MichaelBranscomb for your professional information, I have solved the issue, and i may have made a rookie mistake. I found that I forgot to set the ReturnZ of the geoprocessing parameters to true, the correct code is as follows:

// Create the geoprocessing task from the service
var _gpTask = await GeoprocessingTask.CreateAsync(new Uri(_gpService.Url + "/MyGPModel"));

// Create the geoprocessing parameters
var _gpParams = await _gpTask.CreateDefaultParametersAsync();

// Set the geoprocessing parameters
_gpParams.ReturnZ = true;

 

Thanks
