Detailed Description

Describes an axis in the plane (2D space).
An axis is defined by:

its origin (also referred to as its "Location point"), and
its unit vector (referred to as its "Direction").
An axis implicitly defines a direct, right-handed
coordinate system in 2D space by:
its origin,
its "Direction" (giving the "X Direction" of the coordinate system), and
the unit vector normal to "Direction" (positive angle
measured in the trigonometric sense).
An axis is used:
to describe 2D geometric entities (for example, the
axis which defines angular coordinates on a circle).
It serves for the same purpose as the STEP function
"axis placement one axis", or
to define geometric transformations (axis of
symmetry, axis of rotation, and so on).
Note: to define a left-handed 2D coordinate system, use Ax22d.

Constructor & Destructor Documentation

◆ Ax2d() [1/2]

Geom::Ax2d::Ax2d ( )

Creates an indefinite Ax2d

the axis placement and V is the "Direction" of
the axis placement.

Member Function Documentation

◆ angle()

double Geom::Ax2d::angle ( const Ax2d & Other ) const

Computes the angle, in radians, between this axis and
the axis Other. The value of the angle is between -Pi and Pi.

◆ direction()

const Dir2d& Geom::Ax2d::direction ( ) const

Returns the direction of <me>.

◆ isCoaxial()

bool Geom::Ax2d::isCoaxial	(	const Ax2d &	Other,
		const double	AngularTolerance,
		const double	LinearTolerance
	)		const

Returns True if :
. the angle between <me> and <Other> is lower or equal
to <AngularTolerance> and
. the distance between <me>.Location() and <Other> is lower
or equal to <LinearTolerance> and
. the distance between <Other>.Location() and <me> is lower
or equal to LinearTolerance.

◆ isNormal()

bool Geom::Ax2d::isNormal	(	const Ax2d &	Other,
		const double	AngularTolerance
	)		const

Returns true if this axis and the axis Other are normal to
each other. That is, if the angle between the two axes is equal to Pi/2 or -Pi/2.
Note: the tolerance criterion is given by AngularTolerance.

◆ isOpposite()

bool Geom::Ax2d::isOpposite	(	const Ax2d &	Other,
		const double	AngularTolerance
	)		const

Returns true if this axis and the axis Other are parallel,
and have opposite orientations. That is, if the angle
between the two axes is equal to Pi or -Pi.
Note: the tolerance criterion is given by AngularTolerance.

◆ isParallel()

bool Geom::Ax2d::isParallel	(	const Ax2d &	Other,
		const double	AngularTolerance
	)		const

Returns true if this axis and the axis Other are parallel,
and have either the same or opposite orientations. That
is, if the angle between the two axes is equal to 0, Pi or -Pi.
Note: the tolerance criterion is given by AngularTolerance.

◆ location()

const Pnt2d& Geom::Ax2d::location ( ) const

Returns the origin of <me>.

◆ mirror() [1/2]

void Geom::Ax2d::mirror ( const Pnt2d & P )

◆ mirror() [2/2]

void Geom::Ax2d::mirror ( const Ax2d & A )

◆ mirrored() [1/2]

Ax2d Geom::Ax2d::mirrored ( const Pnt2d & P ) const

Performs the symmetrical transformation of an axis
placement with respect to the point P which is the
center of the symmetry.

◆ mirrored() [2/2]

Ax2d Geom::Ax2d::mirrored ( const Ax2d & A ) const

Performs the symmetrical transformation of an axis
placement with respect to an axis placement which
is the axis of the symmetry.

◆ reverse()

void Geom::Ax2d::reverse ( )

Reverses the direction of <me> and assigns the result to this axis.

◆ reversed()

Ax2d Geom::Ax2d::reversed ( ) const

Computes a new axis placement with a direction opposite to
the direction of <me>.

◆ rotate()

void Geom::Ax2d::rotate	(	const Pnt2d &	P,
		const double	Ang
	)

◆ rotated()

Ax2d Geom::Ax2d::rotated	(	const Pnt2d &	P,
		const double	Ang
	)		const

Rotates an axis placement.

is the center of the
rotation . Ang is the angular value of the rotation
in radians.

◆ scale()

void Geom::Ax2d::scale	(	const Pnt2d &	P,
		const double	S
	)

◆ scaled()

Ax2d Geom::Ax2d::scaled	(	const Pnt2d &	P,
		const double	S
	)		const

Applies a scaling transformation on the axis placement.
The "Location" point of the axis placement is modified.
The "Direction" is reversed if the scale is negative.

◆ setDirection()

void Geom::Ax2d::setDirection ( const Dir2d & V )

Changes the direction of <me>.

◆ setLocation()

void Geom::Ax2d::setLocation ( const Pnt2d & Locat )

Changes the "Location" point (origin) of <me>.

◆ transform()

void Geom::Ax2d::transform ( const Trsf2d & T )

◆ transformed()

Ax2d Geom::Ax2d::transformed ( const Trsf2d & T ) const

Transforms an axis placement with a Trsf.

void Geom::Ax2d::translate	(	const Pnt2d &	P1,
		const Pnt2d &	P2
	)

◆ translated() [1/2]

Ax2d Geom::Ax2d::translated ( const Vec2d & V ) const

Translates an axis placement in the direction of the vector
<V>. The magnitude of the translation is the vector's magnitude.

◆ translated() [2/2]

Ax2d Geom::Ax2d::translated	(	const Pnt2d &	P1,
		const Pnt2d &	P2
	)		const

Translates an axis placement from the point <P1> to the
point <P2>.
