Members

	Name	Description
	Degree	The degree of the Bezier curve. For third degree Beziers, this is always 3.
	Dimension	The topological dimension of this geometry.
	Envelope	Creates a copy of this geometry's envelope and returns it.
	FromPoint	The 'from' point of the curve.
	GeometryType	The type of this geometry.
	GeoNormalize	Shifts longitudes, if need be, into a continuous range of 360 degrees.
	GeoNormalizeFromLongitude	Normalizes longitudes into a continuous range containing the longitude. This method is obsolete.
	GetSubcurve	Extracts a portion of this curve into a new curve.
	IsClosed	Indicates if 'from' and 'to' points (of each part) are identical.
	IsEmpty	Indicates whether this geometry contains any points.
	IsLine	Indicates if the curve degenerated to a line.
	Length	The length of the curve.
	Parameter	The parametric distance along the bezier.
	Project	Projects this geometry into a new spatial reference.
	PutCoord	Sets the specified (0 <= index < 4) control point of this Bezier curve.
	PutCoords	Sets this Bezier curve's control points from an array of between 1 to 4 input points.
	PutWKSCoords	Sets this Bezier curve's control points from the array of 4 input point structures.
	QueryChordLengthTangentAtFrom	Returns tangent vector at 'from' point, based on chord length parametrization; and whether it has been set by user or by smoothing process.
	QueryChordLengthTangentAtTo	Returns tangent vector at 'to' point, based on chord length parametrization; and whether it has been set by user or by smoothing process.
	QueryCoord	Copies the specified control point of this Bezier curve into the input point.
	QueryCoords	Copies this Bezier curve's control points into the array of 4 existing points.
	QueryEnvelope	Copies this geometry's envelope properties into the specified envelope.
	QueryFromPoint	Copies this curve's 'from' point to the input point.
	QueryInflectionPoint	Finds inflection point; sets it empty if none exists.
	QueryNormal	Constructs a line normal to a curve from a point at a specified distance along the curve.
	QueryPoint	Copies to outPoint the properties of a point on the curve at a specified distance from the beginning of the curve.
	QueryPointAndDistance	Finds the point on the curve closest to inPoint, then copies that point to outPoint; optionally calculates related items.
	QueryTangent	Constructs a line tangent to a curve from a point at a specified distance along the curve.
	QueryToPoint	Copies the curve's 'to' point into the input point.
	QueryWKSCoords	Copies this Bezier curve's control points into the array of 4 existing point structures.
	ReverseOrientation	Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc).
	SetChordLengthTangentAtFrom	Establishes tangent vector at 'from' point, based on chord length parametrization; and sets flag whether it has been set by user or by smoothing process.
	SetChordLengthTangentAtTo	Establishes tangent vector at 'to' point, based on chord length parametrization; and sets flag whether it has been set by user or by smoothing process.
	SetEmpty	Removes all points from this geometry.
	SnapToSpatialReference	Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system.
	SpatialReference	The spatial reference associated with this geometry.
	ToPoint	The 'to' point of the curve.
