In this paper, we propose a new unfolding method for a trimmed NURBS surface. We generalize our unfolding method by evaluating the geometric properties along the trim curves on the target NURBS surface. Even in the case of trimmed NURBS surfaces, we can properly compute two patterns of developments by treating the trim curves as like unfolding reference lines. We applied the proposed method to a complex free-form surface of an electric vertical take-off and landing and evaluated the effectiveness of the proposed method by assembling paper-craft scaled models. Using our method, we can compute developments of a complex topological shape represented by trimmed NURBS surface.
