详细描述

Describes an axis in 3D space. An axis is defined by: - its origin (also referred to as its "Location point"), and - its unit vector (referred to as its "Direction" or "main Direction"). An axis is used: - to describe 3D geometric entities (for example, the axis of a revolution entity). It serves 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). For example, this entity can be used to locate a geometric entity or to define a symmetry axis.

构造及析构函数说明

◆ GAx1() [1/2]

GAx1.GAx1 ( )

Creates an axis object representing Z axis of the reference coordinate system.

◆ GAx1() [2/2]

GAx1.GAx1	(	GPnt	theP,
		GDir	theV
	)

P is the location point and V is the direction of <me>.

成员函数说明

◆ Angle()

double GAx1.Angle ( GAx1 theOther )

Computes the angular value, in radians, between this.Direction() and theOther.Direction(). Returns the angle between 0 and 2*PI radians.

◆ Direction()

GDir GAx1.Direction ( )

Returns the direction of <me>.

◆ IsCoaxial()

boolean GAx1.IsCoaxial	(	GAx1	Other,
		double	AngularTolerance,
		double	LinearTolerance
	)

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()

boolean GAx1.IsNormal	(	GAx1	theOther,
		double	theAngularTolerance
	)

Returns True if the direction of this and another axis are normal to each other. That is, if the angle between the two axes is equal to Pi/2. Note: the tolerance criterion is given by theAngularTolerance.

◆ IsOpposite()

boolean GAx1.IsOpposite	(	GAx1	theOther,
		double	theAngularTolerance
	)

Returns True if the direction of this and another axis are parallel with opposite orientation. That is, if the angle between the two axes is equal to Pi. Note: the tolerance criterion is given by theAngularTolerance.

◆ IsParallel()

boolean GAx1.IsParallel	(	GAx1	theOther,
		double	theAngularTolerance
	)

Returns True if the direction of this and another axis are parallel with same orientation or opposite orientation. That is, if the angle between the two axes is equal to 0 or Pi. Note: the tolerance criterion is given by theAngularTolerance.

◆ Location()

GPnt GAx1.Location ( )

Returns the location point of <me>.

◆ Mirror() [1/3]

void GAx1.Mirror ( GAx1 A1 )

◆ Mirrored() [2/3]

GAx1 GAx1.Mirrored ( GAx2 A2 )

Performs the symmetrical transformation of an axis placement with respect to a plane. The axis placement <A2> locates the plane of the symmetry : (Location, XDirection, YDirection) and creates a new axis.

◆ Mirrored() [3/3]
