Curve

Description:
A parametric curve.

Remarks:
The concrete curves are defined by parametric equations. If the curve is bound, it is only defined for an interval in parameterization. Otherwise, it is defined for all values of the parameter.

Name	Return Type	Description	Inherited From
M Clone()	Curve	Returns a copy of this curve.
M ComputeClosestPoints(Curve, Boolean, Boolean, Boolean, IList<ClosestPointsPairBetweenTwoCurves>)	None	Find the closest points between two curves. Closest points mean closest pairs of points, each pair consisting of a point on this, say P1, and a point on other curve, say P2. P1 and P2 are closest locally.
M ComputeDerivatives(Double, Boolean)	Transform	Returns the vectors describing the curve at the specified parameter.
M ComputeNormalizedParameter(Double)	double	Computes the normalized curve parameter from the raw parameter.
M ComputeRawParameter(Double)	double	Computes the raw parameter from the normalized parameter.
M CreateOffset(Double, XYZ)	The new curve.	Creates a new curve that is an offset of the existing curve.
M CreateReversed()	The new curve.	Creates a new curve with the opposite orientation of the existing curve.
M CreateTransformed(Transform)	The new curve.	Crates a new instance of a curve as a transformation of this curve.
M Distance(XYZ)	double	Returns the shortest distance from the specified point to this curve.
M Evaluate(Double, Boolean)	XYZ	Evaluates and returns the point that matches a parameter along the curve.
M GetEndParameter(Int32)	The parameter.	Returns the raw parameter value at the start or end of this curve.
M GetEndPoint(Int32)	The curve endpoint.	Returns the 3D point at the start or end of this curve.
M GetEndPointReference(Int32)	nullNothingnullptr	Returns a stable reference to the start point or the end point of the curve.
M Intersect(Curve)	SetComparisonResult	Calculates the intersection of this curve with the specified curve.
M Intersect(Curve, IntersectionResultArray%)	SetComparisonResult	Calculates the intersection of this curve with the specified curve and returns the intersection results.
M IsInside(Double)	bool	Indicates whether the specified parameter value is within this curve's bounds.
M IsInside(Double, Int32%)	bool	Indicates whether the specified parameter value is within this curve's bounds and outputs the end index.
M MakeBound(Double, Double)	None	Changes the bounds of this curve to the specified values.
M MakeUnbound()	None	Makes this curve unbound.
M Project(XYZ)	IntersectionResult	Projects the specified point on this curve.
M SetGraphicsStyleId(ElementId)	None	Sets the graphics style id for this curve.
M Tessellate()	IList<XYZ>	Valid only if the curve is bound. Returns a polyline approximation to the curve.
M Dispose()	None	Causes the object to release immediately any resources it may be utilizing.	APIObject
M op_Equality(GeometryObject, GeometryObject)	bool	Determines whether two GeometryObjects are the same.	GeometryObject
M Equals(Object)	bool	Determines whether the specified is equal to the current .	GeometryObject
M GetHashCode()	int	Gets the integer value of the geometry object as hash code	GeometryObject
M op_Inequality(GeometryObject, GeometryObject)	bool	Determines whether two GeometryObjects are different.	GeometryObject
