class Point from TDataXtd inherits Attribute from TDF

	---Purpose: 
    	-- The basis to define a point attribute.
    	-- The topological attribute must contain a vertex.
    	-- You use this class to create reference points in a design.
	--          
	--  Warning:  Use TDataXtd_Geometry  attribute  to retrieve the
	--          gp_Pnt of the Point attribute

uses Attribute       from TDF,
     Label           from TDF,
     GUID            from Standard,

     DataSet         from TDF,

    GetID(myclass)

    	-- Returns the GUID for point attributes.

    Set (myclass ; label : Label from TDF) 
    	---Purpose: 
    	-- Sets the label Label as a point attribute.
    	-- If no object is found, a point attribute is created.
    returns Point from TDataXtd;      

    Set (myclass ; label : Label from TDF; P : Pnt from gp)
    	---Purpose: 
    	-- Sets the label Label as a point attribute containing the point P.
    	-- If no object is found, a point attribute is created.
