I have a model which processes a user specified polygon feature class InputFC, with the final result a dissolved (based on a user specified dissolve field D_FIELD) polygon feature class OutputFC. The model also creates a file geodatabase and an empty feature class called FinalFC using InputFC as a template (for the attribute schema).

If I were doing this manually, I would now load the data from OutputFC into FinalFC using the Simple Data Loader in ArcCatalog. Since they have the same table structure, ArcCatalog would automatically match D_FIELD in OutputFC to its matching D_FIELD in FinalFC and load the data into it. The rest of the attributes in FinalFC would be empty. Is this functionality available as a tool for ModelBuilder, or is there a better way to get the dissolved data into the correct table structure?

  • What is the purpose of creating the blank FC template? Couldn't you just use the blank file geodatabase as the output for your dissolved feature class?

  • The dissolved output will only have the one field; I need it to have the same schema as the original input, even if I don't necessarily populate all the attributes with data. Jun 13, 2012 at 5:17

I think the Append tool is what you're looking for. Just make sure the schema_type is set to 'TEST'.

  • This is what I was looking for! I had to set the schema_type to NO_TEST though, as I needed it to match my dissolve field to the final feature class. It worked as expected, with only the dissolve field populated and the other fields empty. Thanks! Jun 13, 2012 at 5:36
