class Ax1 from gp inherits Storable
--- Purpose : 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.
