Public Member Functions
	Geom_Axis1Placement (const gp_Ax1 &A1)
	Returns a transient copy of A1.
	Geom_Axis1Placement (const gp_Pnt &P, const gp_Dir &V)
	P is the origin of the axis placement and V is the direction of the axis placement.
const gp_Ax1 &	Ax1 () const
	Returns a non transient copy of <me>.
void	Reverse ()
	Reverses the direction of the axis placement.
Handle_Geom_Axis1Placement	Reversed () const
	Returns a copy of <me> reversed.
void	SetDirection (const gp_Dir &V)
	Assigns V to the unit vector of this axis.
void	Transform (const gp_Trsf &T)
	Applies the transformation T to this axis.
Handle_Geom_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: 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.
