Variant (three-element array of doubles);
A directional vector representing the end tangent of the spline.
When a spline is elevated, it is converted from an interpolated (fit) spline to a control point spline. This means that after elevation, the spline no longer has fit tangents and the StartTangent and EndTangent properties for the spline are no longer accessible. The only way to edit a control point spline is through the ControlPoints property, or the SetControlPoint or GetControlPoint methods.
