        Parameters
        ----------
        stepName
            A String specifying the name of the step in which the main-secondary assignments are to 
            be modified. 
        index
            An Int specifying the position of the main-secondary assignment whose value is to be 
            modified. 
        value
            A SymbolicConstant specifying the value of the main-secondary role to be assigned to the 
            surface whose index is referenced. Possible values are MAIN, SECONDARY, and BALANCED. 
            The SymbolicConstant BALANCED can be specified only in an Abaqus/Standard analysis.

        Parameters
        ----------
        stepName
            A String specifying the name of the step in which the main-secondary assignments are to 
            be defined. 
        assignments
            A sequence of tuples specifying the main-secondary assignments. Each tuple contains two 
            entries: 
            - A region object or the SymbolicConstant GLOBAL specifying the surface to which the 
            main-secondary attribute is assigned. 
            - A SymbolicConstant specifying the overriding main-secondary value to be used for the 
            first surface. Possible values of the SymbolicConstant are MAIN, SECONDARY, and 
            BALANCED. The SymbolicConstant BALANCED can be specified only in an Abaqus/Standard 
            analysis.
