Thanks Kim I think that is a great workaround - and bonus points for it being ArcStorm inspired. I wrote a Python script to do adaptive tiling for this same client when we were encountering a few features with millions of vertices a year or two ago so we should be able to get some more value from that.  It too was inspired by the way ArcStorm created its tile index. I'm hoping my MaxRecordCount enhancement will get implemented all the same because in this instance I know my client will be happy with a "too many records so won't report on any" response but their original request was to stop copying/reporting at 500. - Graeme ...

Someone else seems to be having a similar AddLayerToGroup problem at Stack Exchange GIS. I think it may be a bug worth investigating but have provided a workaround there which I think should work for some/most use cases. ... View more

Hi Thomas You seem to be mixing up how to refer to layers vs datasets. When you say: r'someLayer', it should just be someLayer (if you have already made a reference to it using ListLayers), or 'someLayer' (if there is a layer in your TOC called someLayer). The 'r' only gets (at least by me) when dealing with backslashes in dataset paths. - Graeme ... View more

Well I found that my code works great for zooming to an extent but fails when displaying by scale and panning.  But yes I still have to set the numbers twice. IEnvelope newEnvelope = mapDoc.ActiveView.Extent.Envelope; newEnvelope.XMin = xMin; newEnvelope.YMin = yMin; newEnvelope.XMax = xMax; newEnvelope.YMax = yMax; newEnvelope.XMin = xMin; newEnvelope.YMin = yMin; newEnvelope.XMax = xMax; newEnvelope.YMax = yMax; mapFrame.MapBounds = newEnvelope; mapFrame.ExtentType = esriExtentTypeEnum.esriExtentBounds; activeView.Refresh(); To get scale to work, I have to do the same thing.  Then I have to save the document and THEN pan to a center point.  It's the only way I could get it to work.  I tried for hours. IEnvelope newEnvelope = mapDoc.ActiveView.Extent.Envelope; newEnvelope.XMin = xMin; newEnvelope.YMin = yMin; newEnvelope.XMax = xMax; newEnvelope.YMax = yMax; newEnvelope.XMin = xMin; newEnvelope.YMin = yMin; newEnvelope.XMax = xMax; newEnvelope.YMax = yMax; mapFrame.MapBounds = newEnvelope; mapFrame.ExtentType = esriExtentTypeEnum.esriExtentBounds; activeView.Refresh(); IPoint point = new Point(); point.X = ((xMin + xMax) / 2d); point.Y = ((yMin + yMax) / 2d); IEnvelope ab = mapFrame.MapBounds.Envelope; ab.CenterAt(point); mapFrame.MapBounds = ab; activeView.Refresh(); Marshal.ReleaseComObject(activeView); Marshal.ReleaseComObject(mapFrame); Marshal.ReleaseComObject(frameElement); Marshal.ReleaseComObject(graphicsContainer); Marshal.ReleaseComObject(map); SaveDocument(); OpenDocument(); map = mapDoc.ActiveView.FocusMap; graphicsContainer = mapDoc.PageLayout as IGraphicsContainer; frameElement = graphicsContainer.FindFrame(map); mapFrame = (IMapFrame)frameElement; activeView = (IActiveView)mapDoc.ActiveView; mapFrame.ExtentType = esriExtentTypeEnum.esriExtentScale; map.MapUnits = esriUnits.esriMeters; mapFrame.MapScale = (double)request.scale; activeView.Refresh(); Marshal.ReleaseComObject(point); Works though. ...

Agreed - BUT ESRI software is famous for its usability. I am a GIS professional and don't struggle to write a python script to call my model in batch... but I have to support other users...and specifically insist they do not use the 'Batch' function they use for other tools as it will fail. And then I have to write a custom python script for them depending on their input data to call my model. And then explain to them how to run the script... And spend lots of time offering support.... I want to be able to tell them right click..batch ... and enter the parameters!!!!!!! ... View more

Splendid, thanks a million.  Only thing I had to do was dedent the DeleteField line so that it did not try to run every time after checking each field. ... View more

We had this issue and it was our Anti Virus software causing it to hang. ... View more

Use the add geometry tool: arcpy.AddGeometryAttributes_management("featureNeedsShape", "AREA") This will add the field "POLY_AREA" to your in_memory feature. Add Geometry Attributes (Data Management)—ArcGIS Pro | Documentation  ... View more

I found a quite simple solution for this problem. You just have to follow three steps when building you rmodel and it will work perfectly. 1.) You have to create a Geodatabase (don't use the default geodatabase from ArcGIS). I've created one in the same folder named "Scratch"; 2.) You need to set all of your output data as non-intermediaries, cause they need to be saved in order to run the model; 3.) Finally, when defining the output of each operation in model builder you have to use the sentence %i%. This is useful to say the mode that it should generate individual intermediate data to each Input of my batch list. For example, if I have a map algebra operator in my model, I should set the name of the output data as Raster_Decli%i%. As a result I would have Raster_Decli0, Raster_Decli1, Raster_Decli2 (...). ...

I'm curious why anyone would demote this idea.  For me, the idea of no longer having to exit ArcMap, start ArcCatalog, change an ArcCatalog Option, exit ArcCatalog and then restart ArcMap to make a new file type available to the Catalog window seems very appealing.  Am I missing something? - Graeme ...

Terry, Despite my efforts, I have been unable to reproduce the error you're seeing on your 64-bit XP machine: ArcCatalog and ArcMap failing to launch once ArcGIS Explorer 1500 is installed.  I tried to mimic your system configuration, but was still unable to recreate the problem. Here are some general "good practice" items to keep in mind when installing ArcGIS Explorer: 1) Stop all of your ArcGIS Services (eg. ArcGIS Server Object Manager) before installing Explorer. 2) Allow all installations to complete without interruption.  The Explorer installation may appear frozen at times, but it's important to allow it to complete. 3)  Review ArcGIS Explorer Knowledge Base Articles here: http://resources.arcgis.com/content/kbase?p=116&fa=tree If the problem persists, I recommend contacting ESRI Support. Thank you very much for the information you've provided and your feedback. All the best, Lindsay ... View more

Yes, when first moving off of ArcInfo workstation to ArcGIS Desktop the ESRI techs kept telling me that a dissolve was equivalent to a DROPLINE.  But DROPLINE is "on-the-fly."   I put in an enhancement request years ago but have no idea what the status is.  With Arcpy the need for this only increases! ...
