▪ Natural—Uses the natural tangent for the defining points of the curve. The natural tangent at the endpoint of a curve is computed with reference to the defining points of the curve when no fixed tangent is specified.

▪ Horizontal—Sets the current direction of the tangent to horizontal, relative to the end planes of the marquee.

▪ Vertical—Sets the current direction of the tangent to vertical, relative to the end planes of the marquee.

▪ Normal—Sets the current direction of the tangent to be perpendicular to the end planes of the marquee.
