When creating a network analysis layer in a Python script, you must first explicitly set the workspace environment to a file geodatabase where you want the layer's data to be stored using arcpy.env.workspace = "<path to file gdb>". When the layer is created, a new feature dataset ...
Input Features The input feature class or layer from which the new layer will be made. Complex feature classes, such as annotation and dimensions, are not valid inputs. Feature Layer Output Layer The name of the feature layer to be created. The layer can be used as input to any geoprocess...
