What's wrong with this model?

Check this out and see what's wrong. I'm working on a model and have the workflow down; I get the result I'm looking for. However my iterator is not kicking in. I've Run the Model, Validated the Model, and Run the Entire Model.

How do I change this to make the iterator kick in? My inputs are multipoint feature classes.

Since you never make use of the changing Name variable, all of your output is saved to the same final feature class ("N2E100_MinimumBoundingGeomet2"). If you name it using in-line variable substitution something like, "%Name%_output", different outputs will be created.

Hi Alex,

Just a workaround. Try storing the feature classes in a feature dataset instead of a GDB directly. Then give the path of the feature dataset in Iterate Feature class.

Thanks,

Jay

Can you explain the difference that storing the feature classes in a feature dataset would make?

ArcGIS Help 10.1 is ESRI's help article that explains the different in-line variable substitutions. That plus Darren's reply helped me get the iterator running properly. Thanks!

I'm not convinced that doing this in ModelBuilder was any faster or easier than scripting it out with a loop; in fact, I accidentally sabotaged the Model when I started poking around in the workspace the Model was working in.

IMO, if you're already scripting there is absolutely no reason to use ModelBuilder.
