I am trying to understand creation of a geoprocess with ModelBuilder, but I don't know why it's important to use feature layers instead of feature classes when creating a geoprocess with ModelBuilder. Can someone please explain why?
Answer
Models may have many sub process output layers depending on their size and complexity. To eliminate files being written onto your hard disk, some tools make you use feature layers (e.g. Iterate Feature Selection, or Select by Attribute). Feature layers are temporary and will not persist after your model ends.
