Copies a network analysis layer to a duplicate layer. The new layer will have the same analysis settings and network data source as the original layer and a copy of the original layer's analysis data.
The tool makes a copy of the input network analysis layer's analysis data (the feature classes and tables referenced by the network analysis layer's sublayers and subtables). The layer's network data source is not copied.
The analysis data is copied to the Current Workspace environment. If this environment is not set, the data is copied to the same geodatabase that contains the analysis data for the input network analysis layer.
| Label | Explanation | Data Type |

(Optional) | The name of the network analysis layer that will be created. | String |
| Label | Explanation | Data Type |
| Output Network Analysis Layer | The newly created network analysis layer. | Network Analyst Layer |
arcpy.na.CopyNetworkAnalysisLayer(in_network_analysis_layer, {out_layer_name})| Name | Explanation | Data Type |
in_network_analysis_layer | The network analysis layer to copy. | Network Analyst Layer |
out_layer_name (Optional) | The name of the network analysis layer that will be created. | String |
| Name | Explanation | Data Type |
| out_network_analysis_layer | The newly created network analysis layer. | Network Analyst Layer |
The following code snippet demonstrates how to copy a network analysis layer in the map using the Python window.
import arcpy
# Retrieve the existing network analysis layer named "Route" from the map
project = arcpy.mp.ArcGISProject("CURRENT")
map_object = project.listMaps()[0]
route_layer = map_object.listLayers("Route")[0]
# Copy the existing layer to a new layer
copied_route_layer = arcpy.na.CopyNetworkAnalysisLayer(route_layer, "Copied Route").getOutput(0)
# Perform further analysis as desired
arcpy.na.Solve(copied_route_layer)
