       int beforePartIndex,
       IEnumerable<Segment> segments
    )
    Public Overloads Sub InsertPart( _
       ByVal beforePartIndex As Integer, _
       ByVal segments As IEnumerable(Of Segment) _
    ) 

    Parameters

    beforePartIndex
    The index before which the part will be inserted. Must be less than or equal to PartCount. Specify -1 or (PartCount) to to insert the part at the end of the Parts list.

    Exceptions
    Remarks
    The spatial reference of each segment is ignored, and the attribute of each segment does not affect the attribute awareness of the builder. However, if the builder has an attribute and the start or end point of a segment also has that attribute, then the attribute value will be taken from the point. If the point doesn't have that attribute, then a default value will be set in the builder. For example, suppose the HasZ property of the builder is set to true. If the HasZ property of a point is set to true, then the point's Z-value is used. Otherwise, the default value is used. The default value for Z is 0, for M is NaN and for ID is 0.
