Syntax DissolveNetwork_na (in_network_dataset, out_workspace_location) Parameter

Fields used in generating driving directions (Street names, Shield, and so on).

Fields used in network attribute evaluators (length, time, one-way restrictions, hierarchy, and so on).

Only fields from the source feature class that are used by the network dataset are transferred to the output line feature class. The tool fails to execute if any datasets with these names already exist in the output geodatabase workspace. The network dataset and feature classes created in the output geodatabase workspace have the same feature dataset name, network dataset name, and feature class names as the input network dataset. Use the Build Network tool to build the newly created network dataset prior to performing any analysis on it. This tool does not create a built network. Learn more about how Dissolve Network works Illustration Usage This tool outputs a new network dataset and source feature classes the input network dataset and its source features remain unchanged.

The more efficient output network dataset reduces the time required to solve analyses, draw results, and generate driving directions. Creates a network dataset that minimizes the number of line features required to correctly model the input network dataset.
