Description

Returns the Turn Direction of the Segment immediately following the current Segment.  The two segments must be connected between the To Point of the first segment and the From Point of the second segment.  ReturnTurnDirection returns a long corresponding to an esriTurnDirectionEnum or a combination of esriNoTurn or esriUTurn and esriRightTurn or esriLeftTurn.  If the two segments are tangential at the point of connection and not completely colinear, then a combination of esriTurnDirectionEnums are returned.

Remarks

ReturnTurnDirection is only available for Lines and CircularArcs, not BezierCurves or EllipticArcs.
