Import Associations (Utility Network)

Summary

Imports associations from a comma-separated values file (.csv into an existing utility network.

Learn more about how to import associations

Usage

• Associations must be in a single .csv file.

• Features listed in the .csv file must exist in the utility network.

• Features listed in the .csv file must have supporting rules.

• This tool can be used in conjunction with the Export Associations tool.

• If an error occurs during import—for example, a missing rule—the entire import process will be rolled back. Review the errors and inspect the .csv file before importing the associations again.

• When working with an enterprise geodatabase, the Input Utility Network must be from a database connection established as the database utility network owner.

• The information in the .csv file is stored in the following format: ASSOCIATIONTYPE, FROMFEATURECLASS, FROMASSETGROUP, FROMASSETTYPE, FROMGLOBALID, FROMTERMINAL, TOFEATURECLASS, TOASSETGROUP, TOASSETTYPE, TOGLOBALID, TOTERMINAL, ISCONTENTVISIBLE, PERCENTALONG.

  .csv columns

  Column	Description	Example
  ASSOCIATIONTYPE	The type of association. Junction Junction Connectivity Junction Edge From Connectivity Junction Edge Midspan Connectivity Junction Edge To Connectivity Containment Structural Attachment	Containment
  FROMFEATURECLASS/TOFEATURECLASS	The feature class or object participating in the association.	ElectricDistributionDevice, ElectricDistributionAssembly, StructureJunction
  FROMASSETGROUP/TOASSETGROUP	The asset group of the feature.	Transformer, Fuse, Elbow
  FROMASSETTYPE/TOASSETTYPE	The asset type of the feature.	Streetlight, Attachment, Single-phase padmounted
  FROMGLOBALID/TOGLOBALID	The global ID of the feature.	{16558C73-013C-4169-A095-7E9DCD57EB57}
  FROMTERMINAL/TOTERMINAL	The terminal participating in the association. This is only applicable to junction-junction connectivity associations.	Single Terminal, Load, Source
  ISCONTENTVISIBLE	A Boolean flag indicating whether the content is visible. This is only applicable to containment associations.	False, True
  PERCENTALONG	The percent along value for junction-edge midspan connectivity associations between a junction object and an edge object.	0.75

Syntax

Parameter	Explanation	Data Type
in_utility_network	The utility network receiving the associations.	Utility Network; Utility Network Layer
association_type	Specifies the type of association to import. ALL —All association types will be imported. JUNCTION_JUNCTION_CONNECTIVITY —The junction-junction connectivity association type will be imported. CONTAINMENT —The containment association type will be imported. STRUCTURAL_ATTACHMENT —The structural attachment association type will be imported. JUNCTION_EDGE_FROM_CONNECTIVITY —The junction-edge connectivity (from side of edge) association type will be imported. JUNCTION_EDGE_MIDSPAN_CONNECTIVITY —The junction-edge connectivity (midspan) association type will be imported. JUNCTION_EDGE_TO_CONNECTIVITY —The junction-edge connectivity (to side of edge) association type will be imported.	String

Code sample

ImportAssociations example (Python window)

This sample script imports all types of associations into a utility network called GridNetwork.

import arcpy
arcpy.ImportAssociations_un("GridNetwork", "ALL", "C:\\Temp\\AllAssociations.csv")

ImportAssociations example 2 (Python window)

This sample script imports junction-junction connectivity associations into a utility network called GridNetwork.

import arcpy
arcpy.ImportAssociations_un("GridNetwork", "JUNCTION_JUNCTION_CONNECTIVITY", 
                            "C:\\Temp\\JJconnectivity.csv")

ImportAssociations example 3 (Python window)

This sample script imports containment associations into a utility network called GridNetwork.

import arcpy
arcpy.ImportAssociations_un("GridNetwork", "CONTAINMENT", 
                            "C:\\Temp\\Containment.csv")

ImportAssociations example 4 (Python window)

This sample script imports structural attachment associations into a utility network called GridNetwork.

import arcpy
arcpy.ImportAssociations_un("GridNetwork", "STRUCTURAL_ATTACHMENT", 
                            "C:\\Temp\\StructuralAttachment.csv")
