Interfaces

Interfaces Description
INetElementDescription Provides access to members that get information about the element described by this NetElementDescription object.
INetElementDescriptionEdit Provides access to members that set information for this NetElementDescription object.

Remarks

NetElementDescription objects are used to add new elements to a logical network.  The AddEdgeByEndEIDs and AddJunction methods on the INetTopologyEdit interface both take NetElementDescription objects as input for creating new elements.

You should only be adding new elements to logical networks that do not have associated geometric networks.  For geometric networks, simply add new features--new elements will automatically be added when you add the new features.
