Can someone point me to a good resource for best practices regarding Geographic Database configuration management.  I have a project that I want to be able to have a "master copy" of input datasets and their results and then allow a user to modify the datasets and generate new results with losing the original input datasets and their respective results.  Hope that makes sense.  Thank you. ...

I will have the need in the near future to render a path through 3d space and would like to represent the aircraft flying this path in the correct position and orientation.  What's the best way to do this using the ArcGIS Pro SDK?  Thanks! ... View more

ArcGIS Pro Experts... 🙂 My team and I have recently completed a basic integration of a number of backend specialized computational methods that are accessible through the Ribbon Buttons create by our ArcGIS Pro AddIn.  The steps to perform the analysis using the buttons has a specific order and explicit dependencies.  For novice users and expert users alike we were considering adding a Wizard or Leveraging Workflow Tasks.  Can someone share what the advantages/disadvantages of one of the other is?  Thank you. Best Regards, Dan ... View more

I have a couple of routines that generate anywhere from 30-40 polygons with approximate 800+ points each.  I call each routine from two different ArcGIS Pro SDK Button Add-In Controls as part of my custom ArcGIS Pro Add-In.  After each routine I take the Polygons that were created add them to the map using the code below (sorry couldn't figure out how to format the coding correctly).  It was working for both buttons consistently until yesterday when only one button would work.  Meaning that I would click one button this routine would run and I'd see my polygons on the map and then I'd push the second button and the second time the routine would get stuck on the bool l_created = l_createFeatures.Execute(); line of code (i.e. Execute() never returned).  After trying several different things I decided that maybe the problem was my database so I shutdown ArcGIS and I deleted the DefaultGeodatabase folder for my project.  I reran and it started working normally again.  Any thoughts on what happened and how I can prevent this from happening again?  See anything wrong with the code below?  Is there a problem with polygons with that many points?  My add-in is in beta release now but would like to know the root of the problem before final release.  Thank you. // First obtain the FeatureLayer based on the name of the layer (l_featureClassName) await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() => {          var l_mapLayers = l_mapView.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>();          foreach (FeatureLayer l_featureClassLayer in l_mapLayers)          {                if (l_featureClassLayer.Name == l_featureClassName)                {                      l_featureLayer = l_featureClassLayer;                      break;                }          } }); //Second Set the Opacity for the Polygons so I can overlapping Polygons await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() => {     //Create polygon outline.     CIMStroke l_outline = SymbolFactory.Instance.ConstructStroke(                                  ColorFactory.Instance.BlackRGB,                                                             1.0,                                            SimpleLineStyle.Solid);     //Create polygon fill with outline.     CIMPolygonSymbol l_fillWithOutline = SymbolFactory.Instance.ConstructPolygonSymbol(     ColorFactory.Instance.CreateRGBColor(0.0, 0.0, 0.0, 0.0),                               SimpleFillStyle.Solid,                                           l_outline);     //Get layer's current renderer.     CIMSimpleRenderer l_renderer = l_featureLayer.GetRenderer() as CIMSimpleRenderer;     //Update current renderer's symbol.     l_renderer.Symbol = l_fillWithOutline.MakeSymbolReference();     //Update layer's renderer.     l_featureLayer.SetRenderer(l_renderer); }); //Third Perform EditOperation to add polygons to layer await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() => {       var l_createFeatures = new EditOperation();       l_createFeatures.CancelMessage = "Operation Cancelled";       l_createFeatures.ErrorMessage = "Error creating polygon";       l_createFeatures.ShowProgressor = true;       // l_arcGISPolygons is List<Polygon>       for (int i = 0; i < l_arcGISResults.Count; i++)       {             l_createFeatures.Name = $"Create Result Polygon #{i}";             l_createFeatures.ProgressMessage = $"Adding Result Polygon #{i} to the Map.....";             //Create a feature with a polygon.             l_createFeatures.Create(l_featureLayer, l_arcGISResults[i]);       }       //Execute the operation.

Part 1:  My team and I were struggling a bit early with creating a FeatureLayer and adding it to the active map using ArcGIS Pro SDK 2.2.  We finally figured it out and were wondering about the Geoprocessing.ExecuteToolAsync which we used.  Is there a list somewhere that shows all the ESRI developed tool paths?  We used "CreateFeatureclass_management" for our purposes and the "cheat" I found was just to go to ArcGIS Pro interface's Python window and import arcpy and then type arcpy. to get the intellisense to help.  But if there was a web page that was available that would be better. Part 2: It appears that we are calling Python code from C# (in our case).  We have the .Net SDK I would think there should be a way to do what "CreateFeatureclass_management" does in C#?  If not why not? Thank you. ... View more

Just added DockPane to my custom ArcGIS Pro Add-In.  My Add-In currently has 2 MapTool Buttons and a regular Button tool already defined and I'm now adding a Dockpane tool.  I'm getting an AggregateException everytime I show the Dockpane but I have not added any code beyond the boiler plate code added by the SDK template (i.e. Add/New Item/Dock Panel).  It does NOT crash when the Dockpane is first shown but if I wait about 30 seconds or less this exception is thrown: System.AggregateException was unhandled Message: An unhandled exception of type 'System.AggregateException' occurred in mscorlib.dll Additional information: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread. Attached are the threads that are running when this crash happens... ... View more
