rectangular cuboid 3d model

Create a strict rectangular cuboid with perfect right angles (90 degrees). The base geometry must remain straight, orthogonal, and stable. The proportions must be exact: length = 7.5 × height length = 7.5 × width. No tilting, no leaning, no trapezoidal shape. Use the attached sketch only as reference for the direction and flow of the folds, not for the base geometry. Add sculpted, fabric-like folds that express directional movement flowing through the volume. The folds must appear carved into the surface, not placed on top. They must be tensioned, stretched, and frozen in motion. No gravity-driven draping. No soft cloth simulation. The folds must affect: – one long face – the two adjacent square faces – and ALSO the opposite long face, so that no long face remains flat. Important correction: The folds on the previously missing long face must match the same direction, tension, and style as the existing folds. Do not change the proportions, base geometry, or existing folds. Do not add new effects. Only comp
