Public Member Functions
	Geom2d_AxisPlacement (const gp_Ax2d &A)
	Constructs an axis by conversion of the gp_Ax2d axis A.
	Geom2d_AxisPlacement (const gp_Pnt2d &P, const gp_Dir2d &V)
	Constructs an axis from a given origin P and unit vector V.
void	Reverse ()
Handle_Geom2d_AxisPlacement	Reversed () const
	Reverses the unit vector of this axis. Note:
void	SetAxis (const gp_Ax2d &A)
	Changes the complete definition of the axis placement.
void	SetDirection (const gp_Dir2d &V)
	Changes the "Direction" of the axis placement.
void	SetLocation (const gp_Pnt2d &P)
	Changes the "Location" point (origin) of the axis placement.
Standard_Real	Angle (const Handle< Geom2d_AxisPlacement > &Other) const
	Computes the angle between the "Direction" of two axis placement in radians. The result is comprised between -Pi and Pi.
gp_Ax2d	Ax2d () const
	Converts this axis into a gp_Ax2d axis.
gp_Dir2d	Direction () const
	Returns the "Direction" of <me>. -C++: return const&
gp_Pnt2d	Location () const
	Returns the "Location" point (origin) of the axis placement. -C++: return const&
void	Transform (const gp_Trsf2d &T)
	Applies the transformation T to this axis.
Handle_Geom2d_Geometry	Copy () const
	Creates a new object which is a copy of this axis.

Detailed Description

• its origin, also termed the "Location point" of the axis,
  
• its unit vector, termed the "Direction" of the axis.
  Note: Geom2d_AxisPlacement axes provide the
  same kind of "geometric" services as gp_Ax2d axes
  but have more complex data structures. The
  geometric objects provided by the Geom2d package
  use gp_Ax2d objects to include axes in their data
  structures, or to define an axis of symmetry or axis of rotation.
  Geom2d_AxisPlacement axes are used in a context
  where they can be shared by several objects
  contained inside a common data structure.
