CoClasses that implement INetElements

CoClasses and Classes Description
StreetNetwork A container for describing a street network.
UtilityNetwork A container for describing a utility network.


Each element in a logical network has a unique Element ID (EID). The EID can be accessed by providing the following three IDs: UserClassID, UserID, and UserSubID.  If the network is part of a geometric network, the UserClassID and UserID correspond to the FeatureClassID and OID of the feature. The UserSubID is the ID of the subelement of the feature.
