I have a button that looks through the active map for a layer group named "LinearRoute" and then gets a feature layer from the route within that group, then it looks for a second layer group called "Crossings" and attempts to intersect the route with each of these layers based on if its a polyline or polygon feature. This is working for the first feature run but the second time through the foreach loop after running intersect it isn't getting the updated feature list from MapView.Active.Map Should I be running this in a different way to ensure I get the results layer from each pass through the Geoprocessing.ExecuteToolAsync loop so my Count doesn't end up null?   protected override async void OnClick() { var project = Project.Current; var projGDBPath = Project.Current.DefaultGeodatabasePath; Map map = MapView.Active.Map; //get group of route feature then Route featuer layer map.GetLayersAsFlattenedList().OfType<GroupLayer>().ToList(); map.GetLayersAsFlattenedList().OfType<GroupLayer>().Where(l => l.Parent.ToString() == "LinearRoute"); var lyrRoute = map.GetLayersAsFlattenedList().OfType<FeatureLayer>().Where(l => l.Parent.ToString() == "LinearRoute" && l.IsVisible == true).FirstOrDefault(); //null check for a feature in the route feature in the linear route group if (lyrRoute is null) { //SendMsg("Intersect", "No Route Layer found in Routes Layer Group"); } else { //check for crossings group layer var lyrCrossings = map.GetLayersAsFlattenedList().OfType<FeatureLayer>().Where(l => l.Parent.ToString() == "Crossings" && l.IsVisible == true).ToList(); if (lyrCrossings is null) { //SendMsg("Intersect", "No Layers found in Crossings Layer Group"); } else { //for each feature in crossings group run intersect based on if its a polyline or polygon crossing. foreach (var lyr in lyrCrossings) { if (lyr.ShapeType == ArcGIS.Core.CIM.esriGeometryType.esriGeometryPolyline) { Map mapNew = MapView.Active.Map; string outputPath = Path.Combine(projGDBPath, lyr.Name + "_Crossing_" + lyrRoute.Name); string resultLyrName = lyr.Name + "_Crossing_" + lyrRoute.Name; List<string> inputList = new List<string>(); inputList.Add(lyrRoute.Name); inputList.Add(lyr.Name); var args = Geoprocessing.MakeValueArray(inputList, outputPath, "", "", "POINT"); string toolPath = "analysis.Intersect"; IGPResult result = await Geoprocessing.ExecuteToolAsync(toolPath, args); //update mapView after geoproccesing tool is run to get newly added results layers mapNew = MapView.Active.Map; int nCount = 0; //GetLayerAsFlattenedList works for the first intersect layer but teh second pass through the foreach loop comes up null FeatureLayer fl1 = mapNew.GetLayersAsFlattenedList().OfType<FeatureLayer>().Where(fl => fl.Name.Equals(resultLyrName, StringComparison.OrdinalIgnoreCase)).FirstOrDefault(); Debug.WriteLine(resultLyrName); await QueuedTask.Run(() => { FeatureClass featureClass = fl1.GetFeatureClass(); nCount = featureClass.GetCount(); }); FrameworkApplication.AddNotification(new Notification() { Title = "MSG", Message = "Feature Count Is: " + nCount.ToString(), }); } else if (lyr.ShapeType == ArcGIS.Core.CIM.esriGeometryType.esriGeometryPolygon) { //same principal but Geoprocessing.MakeValueArray(inputList, outputPath, "", "", "LINE"); } else { //SendMsg("Intersect", "No polyline or polygon crossing layers found"); } } } } }     ...

is there a way using the data interoperability extension to move CAD / Civil 3D object data to a file geodatbase field. In FME Workbench the Map 3D Object Data reader allows the exposure of the attached object data to be mapped to a field in a file geodatabase but I don't see this option in the Data Interoperability extension. ...

Using pro SDK is there a way to determine if a file geodatabase feature has been changed other than enabling and using editor tracking fields to compare the current modified date vs a previous saved modified date. and checking if the record count is the same as it was?  ... View more

Is there a way to check if a toolbox tool exists before opening it using the arcgis pro sdk? When I tried OpenToolDialog()  on a tool not in the toolbox it tried to open it and failed.   string analysisToolName = "C:\\Program Files\\ArcGIS\\Pro\\Resources\\ArcToolBox\\Toolboxes\\Analysis Tools.tbx\\NewToolBuffer"; var param_values = Geoprocessing.MakeValueArray(); param_values = null; if (File.Exists(analysisToolName)) {    Debug.WriteLine("FOUND");    Geoprocessing.OpenToolDialog(analysisToolName, param_values); } else {    Debug.WriteLine("DID NOT FIND TOOL"); } ...

This may be an easy question but looking through the pro sdk samples and guides I didn't see the optimal way of getting a geodatabase feature class length in feet or miles like the python below. How do you get a feature classes full length or selection records length from the @SHAPE fields while supplying the unit of measurement you want? <code> with arcpy.da.SearchCursor(lyr, ['SHAPE@']) as cursor:                 for row in cursor:                     length += row[0].getLength("PLANAR", "FEET")                     print("Total length: {0}".format(length)) </code> similar to the code below but needing to specify the return unit of measurment public static void GetLength(Map map, string layer)         {             QueuedTask.Run(() =>             {                 FeatureLayer fl1 = map.FindLayers(layer).FirstOrDefault() as FeatureLayer;                 QueryFilter queryFilter = new QueryFilter();                 using (ArcGIS.Core.Data.RowCursor rowCursor = fl1.Search(queryFilter = null))                 {                                          double length = 0;                     while (rowCursor.MoveNext())                     {                                                 Feature feature1 = rowCursor.Current as Feature;                         Geometry geo = feature1.GetShape().Clone() as Polyline;                         length += GeometryEngine.Instance.Length(geo);                         Debug.WriteLine(length);                     }                     Debug.WriteLine("total: " + length/5280);                 }             });                     } ...
