class Geometry from TDataXtd inherits Attribute from TDF
---Purpose: This class is used to model construction geometry.
-- The specific geometric construction of the
-- attribute is defined by an element of the
-- enumeration TDataXtd_GeometryEnum.
-- This attribute may also be used to qualify underlying
-- geometry of the associated NamedShape. for
-- Constructuion element by example.

-- =================
Set (myclass ; label : Label from TDF)
---Purpose: Finds, or creates, a Geometry attribute defined by the label label.
-- The default type of geometry is the value
-- ANY_GEOM of the enumeration TDataXtd_GeometryEnum.
-- To specify another value of this enumeration, use
-- the function SetType.

returns mutable Geometry from TDataXtd;
---Purpose: This and the next methods are used to retrieve underlying geometry of the
-- NamedShape, even if noone Geometry Attribute is
-- associated . if not found or not compliant geometry return False.
SetType (me : mutable; T : GeometryEnum from TDataXtd);
---Purpose: Returns the type of geometric construction T of this attribute.
-- T will be a value of the enumeration TDataXtd_GeometryEnum.
