2. In the Search Results dialog that opens, click the Show Details button associated with the datum.
3. In the Datum Attributes dialog that appears, click the Actions button dropdown and select Assign Geometry.
   Note: This option is only available if the current datum record does not have a spatial representation.
4. You are now in editing mode and the digitizing tool is active. Click the map to place vertices. Double-click to finish drawing.
5. Click Save to assign the new geometry to the datum.
