Did you check if the spatial references for raster and shapefile match?

Try Iteration in ModelBuilder. + Another way to load data is using the Append geoprocessing tool. This is useful if loading data is going to be used as part of a batch process. May be this helps.

Hi Shiko, How are you selecting the polygons? Are you sure the selection is being passed to the next tool? How is your output incorrect? Are the values wrong or all records Null? Always consider attaching a snapshot of the model with the forum post. It makes it easier to see the upstream and downstream processes.

Hi, There are two things to change in the model: The rule is "The tools that only need to be run once should be placed in the main model, which calls the iterating submodel." Merge and Dissolve (I am assuming) need to be run just once so they should be in the main model which calls the sub model containing an iterator. Any tool placed in the same model as the iterator will run as many times as the iterator runs and I think you don't want the merge and dissolve to run more than once. Read the Advanced use of Iterator section from the link. Since you are using the iterator the Value output of the iterator (cyan color) has the value of the field over which you are iterating it can be used in the output for clip C:\Temp\Out_%Value%.shp using inline variable substitution.

Can you share a snapshot of the model you have created?

Try the tool Get Field Value after selection and use the output of the tool as inline variable substitution in the output path name.

arcpy.env.worspace should be a workspace like a folder or a geodatabase and not a path to a specific shapefile. May be this is the issue. or when you pass a path in the expression you should do it like this: r"%Workspace%". or This error code covers a number of Python errors: Example error 1: exceptions.TypeError: cannot concatenate 'str' and 'int' objects. The above is a Python-specific error. The calculation is attempting to add or concatenate a string and a number. Example error 2: Invalid field shape@distance The above is an error using the geometry object. The distance method is not a valid method of the geometry object.

Ok. Try this: Read this blog If you are stuck at if Part 4 Download the script tool from the link in the blog. Then try to create a model as shown in the attachment.

ok. Lets try again. So you have some string values provided by the user say : Babbler, Sparrow and Crow. You want to check if any or all? Babbler, Sparrow and Crow values exists in a field called birds in your input feature class. Is this correct? How do users provide these values. A separate variable for each user input, meaning a variable for Babbler, another separate variable for Sparrow and so on? or the user provides these values in a single multivalue variable? You want to check if a particular value exists in a field????

Hi You want to check if a particular field exists in a feature class or not: if this is correct: check the attached example of how to use the Calculate Value tool and the python code. Hope this helps. Let me know.

Hi Shiko, Try this: Create a model: - Use a selection tool like make feature layer/ Select a layer By attribute/Select to select the records and then pass the output selection to the Summary Statistic Tool : Summing the field you want to for the selected records > then use the Get Field Value tool (Only works in ModelBuilder) to get the sum value from the statistic table. You can then use this sum value in the tool you want. You can make the output of the summary statistic tool in_memory so that you don't have to save an extra dbf table. Hope this helps.

Hi, Can you let the last output of the iteration that you want to delete and use in feedback be overwritten for each iteration rather than creating a new one per iteration? This way you don't need to delete all the outputs except the last. You can do this be leaving the last output name that is not unique for each iteration: c:\Temp\abc : This way the same abc gets created for every iteration.
