ArcFM Configuration for the Utility Network Definition

​The ArcFM Utility Network (UN) Configuration Guide is a collection of concepts, requirements, and recommendations for applying UN-specific models to electric power facility domains. These models are designed to be extensible and lets you create a better collaboration between Esri, utilities, and vendors to lower implementation costs.

Schneider Electric provides custom UN models or asset packages, to make the ArcFM Solution XI series products easier to implement. Any packages that predate Version 4 of the UN are supported, but must be configured to get the most productivity from the solution.

Service Territory - Spatial Reference

The Service Territory Feature Class defines the spatial reference for the UN feature classes. If you want to add to, update, or edit the Service Territory, these changes must be done before you create the UN. Once this spatial reference has been defined and the UN has been created, it cannot be changed.

Some ArcFM tools require the ability to assign negative Z values for below grade elevations. Before starting any data conversion, you must select a spatial reference with a vertical coordinate system with a direction of positive up and a resolution that defines a minimum Z value with negative values.

You can see the minimum Z value in the Service territory properties.

To set this vertical system:

1. From the content pane in ArcGIS Pro, right click on the name of your map and select properties.

2. In the left side menu, click Coordinate Systems.

3. If the Current Z box says <None, > click the box.

4. In the search box, enter navd88 and hit enter.

5. Expand the menu from Vertical Coordinate System > Gravity-related > North America.

6. Select NAVD88 height (ftUS) from the list and click OK.

   For more information, see the Esri topic Vertical Coordinate Systems.

ArcFM Editor XI continues to release new Out of the Box Autoupdaters to support UN connectivity rules and associations. For more information, see OOTB Autoupdaters.
