The PositionAlongObject property determines, from the given positional value along the edge element, the corresponding positional value along the object from which this edge element was created. The positionAlongElement parameter and the PositionAlongObject value both range from 0.0 to 1.0.
For example, if the fromPosition and toPosition values from the QueryPositions method is 0.1 and 0.6 respectively, then the PositionAlongObject value for the positionAlongElement = 0.7 is equal to 70% of the way between 0.1 and 0.6, which is 0.45.

Remarks
The QueryEdgeInOtherDirection method retrieves the edge element in the opposite direction of travel as this edge.
This method requires an instantiated NetworkEdge object to be passed in as a parameter. You can create an empty NetworkEdge object by using the INetworkQuery::CreateNetworkElement method.

Public Sub QueryPositions ( _
ByRef fromPosition As Double, _
ByRef toPosition As Double _
)
public void QueryPositions (
ref double fromPosition,
ref double toPosition
);
Remarks
The QueryPositions method queries the positional values along the source feature from which this edge element was created. The position values range from 0.0 to 1.0, where 0.0 is at the from-end of the feature and 1.0 is at the to-end of the feature.
If the Direction property is esriNEDAlongDigitized, then the fromPosition value will be less than or equal to the toPositionValue. If the Direction property is esriNEDAgainstDigitized, then the fromPosition value will be greater than or equal to the toPositionValue.
INetworkEdge.QueryTurn Method

public void QueryTurn (
int Index,
INetworkTurn Turn
);
Remarks
The QueryTurn method retrieves the turn element that traverses this edge at the specified index. The index values range from 0 to (TurnCount - 1).
The QueryTurn method requires an instantiated NetworkTurn object to be passed in as a parameter. You can create an empty NetworkTurn object by using the INetworkQuery::CreateNetworkElement method.
