		const OdGeTol &	tol = `OdGeContext::gTol`
	)		const

◆ paramAtLength()

double OdGeCurve3d::paramAtLength	(	double	datumParam,
		double	length,
		bool	posParamDir = `true`,
		double	tol = `OdGeContext::gTol.equalPoint()`
	)		const

Returns the parameter of the point a specified distance from the starting point corresponding to datumParam.

Parameters

datumParam	[in] Parameter corresponding to the start point.
length	[in] Distance along curve from the start point.
posParamDir	[in] True if and only if returned parameter is to be greater than dataParam.
tol	[in] Geometric tolerance.

◆ paramOf()

double OdGeCurve3d::paramOf	(	const OdGePoint3d &	point,
		const OdGeTol &	tol = `OdGeContext::gTol`
	)		const

Returns the parameter value of a point.

Parameters

point	[in] Point to be evaluated.
tol	[in] Geometric tolerance.

Remarks: The returned parameters specify a point within tol of point. If point is not on this curve, the results are unpredictable. If you are not sure the point is on this curve, use isOn () instead of this function.; By default this function throws exception "not Implemented". Should be implemented in derived classes.

Throws:

eNotImplemented

◆ projClosestPointTo() [1/2]

OdGePoint3d OdGeCurve3d::projClosestPointTo	(	const OdGeCurve3d &	curve,
		const OdGeVector3d &	projectDirection,
		OdGePoint3d &	pntOnOtherCrv,
		const OdGeTol &	tol = `OdGeContext::gTol`
	)		const

Returns the point on this curve closest to the specified curve, and the point on the other curve closest to this curve, when this curve is projected in the specified direction.

Parameters

curve	[in] Any 3D curve.
projectDirection	[in] Projection Direction.
pntOnOtherCrv	[out] Receives the closest point on other curve.
tol	[in] Geometric tolerance.

Remarks: By default this function throws exception "not Implemented". Should be implemented in derived classes.

Throws:

eNotImplemented

◆ projClosestPointTo() [2/2]

OdGePoint3d OdGeCurve3d::projClosestPointTo	(	const OdGePoint3d &	point,

	)		const

Returns the point on this curve closest to the specified point when this curve is projected in the specified direction.

Parameters

point	[in] Any 3D point.
projectDirection	[in] Projection Direction.
tol	[in] Geometric tolerance.

Remarks: By default this function throws exception "not Implemented". Should be implemented in derived classes.

Throws:

eNotImplemented

	)		const

◆ reverseParam()

OdGeCurve3d& OdGeCurve3d::reverseParam ( )

Reverses the parameter direction this curve.

Remarks: The point set of this curve is unchanged.; By default this function throws exception "not Implemented". Should be implemented in derived classes.

Throws:
