Public Member Functions inherited from Geom_AxisPlacement
void	SetAxis (const gp_Ax1 &A1)
	Assigns A1 as the "main Axis" of this positioning system. This modifies.

void	SetLocation (const gp_Pnt &P)
	Assigns the point P as the origin of this positioning system.

Standard_Real	Angle (const Handle< Geom_AxisPlacement > &Other) const
	Computes the angular value, in radians, between the "main Direction" of this positioning system and that of positioning system Other. The result is a value between 0 and Pi.

const gp_Ax1 &	Axis () const
	Returns the main axis of the axis placement. For an "Axis2placement" it is the main axis (Location, Direction ). For an "Axis1Placement" this method returns a copy of <me>.

	Returns the main "Direction" of an axis placement.

gp_Pnt	Location () const
	Returns the Location point (origin) of the axis placement.

Public Member Functions inherited from Geom_Geometry
void	Mirror (const gp_Pnt &P)
	Performs the symmetrical transformation of a Geometry with respect to the point P which is the center of the symmetry.

void	Mirror (const gp_Ax1 &A1)
	Performs the symmetrical transformation of a Geometry with respect to an axis placement which is the axis of the symmetry.

void	Mirror (const gp_Ax2 &A2)
	Performs the symmetrical transformation of a Geometry with respect to a plane. The axis placement A2 locates the plane of the symmetry : (Location, XDirection, YDirection).

void	Rotate (const gp_Ax1 &A1, const Standard_Real Ang)
	Rotates a Geometry. A1 is the axis of the rotation. Ang is the angular value of the rotation in radians.

void	Scale (const gp_Pnt &P, const Standard_Real S)
	Scales a Geometry. S is the scaling value.

void	Translate (const gp_Vec &V)
	Translates a Geometry. V is the vector of the translation.

Detailed Description

Describes an axis in 3D space. An axis is defined by:

its origin, also termed the "Location point" of the axis,
its unit vector, termed the "Direction" of the axis. Note: Geom_Axis1Placement axes provide the same kind of "geometric" services as gp_Ax1 axes but have more complex data structures. The geometric objects provided by the Geom package use gp_Ax1 objects to include axes in their data structures, or to define an axis of symmetry or axis of rotation. Geom_Axis1Placement axes are used in a context where they can be shared by several objects contained inside a common data structure.
