class Axis from TDataXtd inherits Attribute from TDF


	---Purpose: The basis to define an axis attribute.

	--  Warning: Use TDataXtd_Geometry  attribute  to retrieve  the
	--          gp_Lin of the Axis attribute

uses Attribute       from TDF,

-- In the case of a creation of an axis, a compatible
-- named shape should already be associated with label.
-- Exceptions
-- Standard_NullObject if no compatible named
-- shape is associated with the label.

    ---Purpose: Find,  or create,  an Axis  attribute  and set <P>  as
    --          generated in the associated NamedShape.
