How to Exclude Processes from Iteration in ModelBuilder?

Question

Is it possible to break Iterate Raster after certain set of processes ?

I have a list of Image files which I am processing using Iterate Rasters and performing aggregate and Extract Values to Points and then writing the output to a textfile.

I have three processes:

1. Aggregate
2. Extract Values to Points
3. Writing to textfile

I want to execute process 1 and 2 in Iterate, but 3 Process I don't want to perform in the Iteration. Instead, I want to perform process 3 after all the Iteration got completed for the 1 and 2 process in the same Model.

Anybody has any idea how can I achieve this in the same model?

Answer 1

One solution is to use the iterations portion as a completed model, then use that model inside of another that performs the remaining operations on the output of the iteration model. This is called a nested model. Also, consider looking into Python scripting, the options for dropping into and out of iterations are much more flexible.
