The abstract class AxisPlacement describes the
//! common behavior of positioning systems in 3D space,
//! such as axis or coordinate systems.
//! The Geom package provides two implementations of
//! 3D positioning systems:
//! - the axis (Geom_Axis1Placement class), which is defined by:
//! - its origin, also termed the "Location point" of the axis,
//! - its unit vector, termed the "Direction" or "main
//! Direction" of the axis;
//! - the right-handed coordinate system
//! (Geom_Axis2Placement class), which is defined by:
//! - its origin, also termed the "Location point" of the coordinate system,
//! - three orthogonal unit vectors, termed
//! respectively the "X Direction", the "Y Direction"
//! and the "Direction" of the coordinate system. As
//! the coordinate system is right-handed, these
//! unit vectors have the following relation:
//! "Direction" = "X Direction" ^
//! "Y Direction". The "Direction" is also
//! called the "main Direction" because, when the
//! unit vector is modified, the "X Direction" and "Y
//! Direction" are recomputed, whereas when the "X
//! Direction" or "Y Direction" is modified, the "main Direction" does not change.
//! The axis whose origin is the origin of the positioning
//! system and whose unit vector is its "main Direction" is
//! also called the "Axis" or "main Axis" of the positioning system.
class Geom_AxisPlacement : public Geom_Geometry { public: //! Assigns A1 as the "main Axis" of this positioning system. This modifies
//! - its origin, and
//! - its "main Direction".
//! If this positioning system is a
//! Geom_Axis2Placement, then its "X Direction" and
//! "Y Direction" are recomputed.
//! Exceptions
//! For a Geom_Axis2Placement:
//! Standard_ConstructionError if A1 and the
//! previous "X Direction" of the coordinate system are parallel.
Standard_EXPORT void SetAxis(const gp_Ax1& A1) ; //! Changes the direction of the axis placement.
//! If is an axis placement two axis the main "Direction"
//! is modified and the "XDirection" and "YDirection" are
//! recomputed.
//! Raises ConstructionError only for an axis placement two axis if V and the
//! previous "XDirection" are parallel because it is not possible
//! to calculate the new "XDirection" and the new "YDirection".

Standard_EXPORT void SetLocation(const gp_Pnt& P) ; //! 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.
