Using ArcFM Solution Desktop
Compatible Units
| ArcFM Desktop Overview > Designer > Designer Basics > Compatible Units |
You can place compatible units (CUs) on the map to represent specific utility equipment. A CU carries information about the feature or table it represents.
Typically, a CU is made of two layers: the GIS unit (GU) and CU. The GU contains a reference to the object (or feature) class and subtype as well as the CU-defining attributes. The CU represents the feature and its WMS information (e.g., work function). A single GU may have multiple CUs (with various work functions).

CU-Defining Attributes
CU-defining attributes designate the features of that specific CU. A pole’s height and class are examples. Your administrator determines CU-defining values. They are non-editable and displayed as gray on the Attribute Editor.
Figure 1, the CU-defining attributes are reflected in the CUs name
Multiple CUs
A GU can have multiple assigned CUs to designate an upgrade, removal, or replace. For example, a GU may have a CU with an Install work function and a CU with a Remove work function to indicate that one is being removed and another installed (Replace).
