I have a suitability matrix which was created in model builder based on elevation data and multiple start data points and end data points representing schools.

I'd like to link all the schools up using cost paths.

I can only use one iterator in model builder so was wondering how best to do this.

Many thanks

I'm actually trying to do something similar, but instead of setting up a single network I have 250 start points and 10 end points distributed, what I want to do is assign an end point by simple proximity and then develop least cost paths for each start point to their assigned end point. To do that, I am working in steps and only using the iterator for each set of points by iterating the feature classes. It sounds like you could construct a simple stepwise network, so perhaps instead of iterators you could batch? – user30747 May 28 '14 at 19:27
