Hi Richard, Thanks for posting this tool. I am using it, and I am able to use it easily on a on-time basis but when I try to use it in a python loop I am having trouble. My loop works (calling variables from a list) as I have used it on various other tools. I Receive an error: " Runtime error  Traceback (most recent call last):   File "<string>", line 9, in <module>   File "Y:\Desktop\ARCGIS\Toolboxes\ConcaveHullByCase\ConcaveHullByCase.tbx", line 82, in ConcaveHull     Z17xTbqLuWUQybYfJO0bSqn5JMZYbcN3yTjgg05tS0LTUVdnpln4gm8Hauuo2W6SymYfaLYg4cH+ ExecuteError: Failed to execute. Parameters are not valid. ERROR 000732: Input Points: Dataset "Amsterdam.shp" does not exist or is not supported Failed to execute (ConcaveHull).  I have changed the script to remove the .shp. extension and have the same result. I have run the tool on the shape file in arc, without a script and it works fine. I am running my loop script by copying it into a python window in arc, and executing it there, with all of the relevant shape files open in the workspace.... I have many datasets on which I am trying to run your tool and the loop would make things easy.... Thanks  Michael Hi Richard, Thanks for your reply. I worked it out this morning - In previous uses of my Loop with other toolboxes, the way to call the variable was slightly different, and I had not made that change so it works fine now. The previous use (select data) was ' plume = "NAME = '" + var + "'" but to loop your file I just needed 'plume = var' so the resulting call line was: arcpy.ImportToolbox("Y:\Desktop\ARCGIS\Toolboxes\ConcaveHullByCase\ConcaveHullByCase.tbx") list = ['Amsterdam', 'Bowie']; for var in list: plume = var outpath = outpathbase + var + 'Conc' arcpy.ConcaveHull(plume,"10",outpath,"#","#") my full list has 81 variables, and I need to run this on several different datasets, and then repeat several times so your script has saved me  a huge amount of time.......

Thanks Jake, it turned out to be just one step that made all the difference. After completing an action once, I just went to pull-down list of: geoprocessing\results and then right-click on the process that I had just completed, and copied as python script, then pasted that command line into a python script that I had written to batch process layers. Given that I had seven different steps using 40 layers, with some steps seeking intersections between layers, this saved me a few days work. ... View more
