Hi, Theres some stuff about field maps here also that may help you! https://community.esri.com/thread/185431-append-tool-and-field-mapping-help-examples

You are exporting a "Map", it sounds like you want to export "Data" As you dont provide a "Dataframe" parameter in this line of code, you will get that. arcpy.mapping.ExportToPDF(mxd, export + "\\" + preFix + pageName + ".pdf", resolution = res, df_export_width=1600, df_export_height=1200*ar, geoTIFF_tags=True) From help: ExportToTIFF (map_document, out_tiff, {data_frame}, {df_export_width}, {df_export_height}, {resolution}, {world_file}, {color_mode}, {tiff_compression}, {geoTIFF_tags}) data_frame A variable that references a DataFrame object. Use the string/constant "PAGE_LAYOUT" to export the map document's page layout instead of an individual data frame. (The default value is PAGE_LAYOUT)

You can and most likely do have multiple pythons on your computer! Therefore, your IDE is hooked up to the wrong python! E.g. if you type into dos: python C:\myfile.py it actually looks in a windows registry, and runs: (as an aexample, not your setup!) C:\python27\python.exe C:\myfile.py You need to make sure whatever you use to run it, uses the correct python.exe (Installed when you setup arcgis). This setup stage, should also allow autocomplete to work using any python IDE.

mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd") df = arcpy.mapping.ListDataFrames(mxd)[0] #the 1st data frame print df.extent print df.extent.XMin print df.extent.XMax print df.extent.YMin print df.extent.YMax ‍‍‍‍‍‍‍‍

import arcpy distances = ["1 Mile", "2 Mile"] for distance in distances: outfile = "wp%s" % distance arcpy.Buffer_analysis(SP, outfile, distance, "FULL", "ROUND", "", "BUFF_DIST") out = arcpy.env.workspace lyr = ["wp1 Mile", "wp2 Mile"] #shplist = arcpy.ListFeatureClasses(lyr, "Polygon") merge_out_path = os.path.join(out, "mile1_2") arcpy.Merge_management(lyr, merge_out_path) dissolve_out_path = os.path.join(out, "mile1_2_dissolved") arcpy.Dissolve_management(merge_out_path, dissolve_out_path, ["BUFF_DIST"])‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ This will give you the geometry you want. You need to work out how to combine the attributes yourself if needed. (e.g. the features in 1 mile, you have multiple Account Numbers + Pins that you now want to store in 1 row.

Hi there! The "OpenDocument" trigger, does not call an init, your code should probably look like this. import arcpy import pythonaddins class JoinRoads(object): """Implementation for RoadsScript_addin.extension2 (Extension)""" def openDocument (self): Roads_2015 = "Roads 2015" Roads_2015__2_ = Roads_2015 All_roads = "private\\transportation_FA_wa\\All roads" # Process: Add Join arcpy.AddJoin_management(Roads_2015, "BRUCE_ID", All_roads, "BRUCE_ID", "KEEP_ALL")‍‍‍‍‍‍‍‍‍‍‍‍

If you had issues with indentation in pyscripter using your notepad ++ file, it sounds like you have got your notepad setup wrong for python! The problem is, you are mixing "Tabs" with "Spaces" To fix --> Open notepad ++ "Settings" --> "Preferences" --> "Language Menu / Tab Settings" Find Python On the right, tick the box "replace by space" and choose a number of spaces. Now when you use tab, it will behind the scenes put in spaces, and make sure that what you see is exactly as python will read the indentation.

You cant do what you asked. You can however achieve the exact same results by: Add 10 scale bars with unique names 'Off page', in different styles and stuff, and then use python to move them onto the page as needed for different maps. OR Create 10 "MXD" templates with different page setups, and use the code to determine which template to use. OR Think of something else ..be creative!

I have found testing to be 1000x easier since I installed my Add-in using a network location, instead of manually! 1) Delete the add-in if you already installed it. 2) Customise --> Add-in manager --> Options --> Search for additional add-ins in these folders" 3) Add the location that your "makeaddin.py" creates the .esriaddin file as a location. 4) Now, if you run "makeaddin.py", then reboot arcmap, you are using the latest version of the code without having to do an extra click to install it!

Please provide us with your script to maybe help us out a bit more, are the fields named the same in the Feautreset as the Table you tested with? Could you do: featureset = arcpy.FeatureSet() featureset .load(input_data) featureset .save(temporary_table.shp) tool_run(temporary_table.shp)

My understanding of field mappings is you create an empty fieldmap. fieldmappings = arcpy.FieldMappings() Then you popupulate it using tables like we did, or alternatively you could do it totally manually as the example on the help page shows. There they create an output field mapping that has 2 fields. It looks pretty complex but heres a simple, 1 field output map! input_file1 = 'data.gdb/Trees' input_file2 = 'Plants.shp' ######You could loop this bit field_map = arcpy.FieldMap() field_name_input_file1 = "Tree_Type" field_name_input_file2 = "Tree_Species" field_map.addInputField(input_file1, field_name_input_file1) field_map.addInputField(input_file2, field_name_input_file2) field_map.name = 'Tree_Classification' fieldmappings.addFieldMap(field_map) With this in mind, our output fieldmap we have created, actually contains all of the 'target' and all of the 'append' layers fields, but as you are running append you dont see all the unmatched 'append' fields in the output. If you ran the same field map through a merge, you would end up with all the append layers fields as well.

The creators pretty bad but I have a workaround that works for me every time: 1) Take a copy of my "Addin.py" file with the UI (button) code in. 2) Delete the config.xml 3) Resave the addin using the wizard. (change a text box and then back if the save button is greyed out.) 4) Delete the new Addin.py file, and put mine back. I have no idea if this is it, but in In my config.xml files, in the 'toolbar' line of code, the refID matches the Class in the buttonas, in yours the Toolbar simply references 'button' not 'ButtonClass1' <Button caption="Select by Location" category="Select by Location" class="ButtonClass1" id="SelectbyLocation_addin.button" image="Images\SelectionSelectByLocation16.png" message="Select by Location" tip="Select by Location"><Help heading="Select by Location">Select by Location</Help></Button> Button refID="SelectbyLocation_addin.button" # ---> Change to Button refID="SelectbyLocation_addin.ButtonClass1" in this line of code: <Toolbar caption="select by location" category="Select by Location" id="SelectbyLocation_addin.toolbar" showInitially="true"><Items><Button refID="SelectbyLocation_addin.button" /></Items></Toolbar>

Make sure the tool is called "SelectByLocation" when you set up the toolbox in Arc through the GUI, that might be the label or description instead! Im not sure, but you could try open arcmap, then open the python window, then drag your tool from the toolbox into the window, it should maybe tell you what its name is there.
