        Parameters
        ----------
        stepName
            A String specifying the name of the step in which the surface feature assignments are to
            be modified.
        index
            An Int specifying the position of the surface feature angle assignment whose value is to
            be modified.
        value
            A tuple specifying the value of the surface feature assignments for the surface whose
            index is referenced. Each tuple contains two entries for Abaqus/Standard and three
            entries for Abaqus/Explicit:
            - A Float or a SymbolicConstant specifying the overriding surface primary feature angle
            value to be used for the surface. Possible values of the SymbolicConstant are PERIMETER,
            ALL, PICKED, or NONE. The ALL and PICKED values cannot be specified with the GLOBAL
            region constant and can be used only in the Abaqus/Explicit version of general contact.
            - A Float or a SymbolicConstant specifying the overriding surface secondary feature
            angle value to be used for the surface. Possible values of the SymbolicConstant are
            PERIMETER, ALL, PICKED, or NONE. The ALL and PICKED values cannot be specified with the
            GLOBAL region constant and can be used only in the Abaqus/Explicit version of general
