package PGeom2d 

        ---Purpose :  This  package contains   the definition   of the
        --         geometric persistent objects such as point, vector,
        --         axis placement, curves, surfaces.
        --  
        --  All these entities are defined in 2D space.
        --  This package gives the possibility :
        --    . to create geometric objects with given or default field values,
        --    . to set field values,
        --    . to get field values.
