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.

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.

Queries the index'th network turn element in which this network edge element participates.

Public Sub QueryTurn ( _
    ByVal Index As Integer, _
    ByVal Turn As INetworkTurn _

    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).
