Abstract: We want to create interactive surface design systems which 
        provide intuitive interfaces to parametric surface 
        representations.
        In this paper, we show how the technique of Differential
        Manipulation can be used in constructing such interfaces.
        It allows surface manipulation issues to be treated separately
        from surface representation issues.
        Arbitrary differentiable functions of representation parameters
        can be used to control the surface.
        Constraint and optimization techniques can be used to control
        many surface degrees of freedom at once.
        We provide examples of the technique's use in our interactive
        surface modeling program.
