Most general, shearfree and twistfree geometry is revisited and its Weyl scalars are obtained with large D limit. It is shown that, the spacetime is Type I(b) or more special in this limit like the classification of any arbitrary dimesion D > 4. As an example, classification of vacuum RT spacetime is investigated. As expected, the spacetime becomes algebraically special and it is Type II or more special. Obligatory conditions are determined for other types and sub-types as the dimension of the spacetime D → ∞
