Hi,I am looking for a way to automate workflow in creating and building network dataset. I have already automated all the pre-requisites like building file geo database , merge , join and export using python script. Is there any way in ARCGIS 10 that I can use to add attributes and parameters for a network data set , applying a custom evaluator to a cost attribute and create/build network dataset using any scripting tool. Any help on this would be appreciated. Thanks in advance.
