    Exceptions
    Remarks
    The spatial reference of the segment is ignored, and the attribute of the 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.
