how to Iterate files and iterate features

RamB — Thu, 27 Jul 2017 10:36:56 GMT

Hi,

I have a folder with 4 primary shape files. Each shapefile has a field "direction". I want to split each primary shapefile based on the field direction which has 4 (NSEW) directions. So the output should be 4x4 = 16 shape files.

I am able to input one primary shapefile and use iterate feature selection to split "one" shapefile to "four" shape files. But I am not able to loop to the second primary shapefile ( of the 4 original files in my folder).

how can I make this work? Please guide.

Try Iterate Feature Classes—Help | ArcGIS for Desktop since shapefiles are a type of feature classes. Also you might need to use the in-line variable.

The tool has two outputs: Output Feature Class and Name, which could be used as in-line variable (e.g. %Name%) in other tools.

Hi,

Yes, I did that, but since only one iterator is allowed in a model, I created a submodel. Here in the image, on the right is iterate feature class, then for each feature class, I am calling a sub model that splits each feature class and "copy features" to a shapefile.

I think my data is getting overwritten, because i see the values of the fourth layer as the final output.

Not sure where I am doing it wrong.

Write %n% in the end of the path of model1 output . to prevent overwrite.
