S-Curve Oak Bench with Ivory Cushions

Create a detailed, fully editable parametric 3D CAD model of the architectural bench shown in the reference image, suitable for Rhino 3D. Design: • Create a continuous, smooth S-shaped organic bench. • Overall dimensions: 4500 × 900 × 450 mm (L × W × H). • Include two wide, rounded seating areas connected by a narrower, smoothly flowing middle section. • Preserve the sculptural form with smooth tangent transitions and rounded edges. Wooden Structure: • Use natural light oak wood. • Create individually editable parallel wooden ribs following the entire S-shaped geometry. • Rib thickness: 20–30 mm, with consistent spacing and small gaps. • Ensure smooth edges, uniform distribution, and no intersections. Cushions: • Add two separate, editable upholstered cushions. • Use warm ivory or soft white. • Give them organic curved shapes, rounded ends, and slightly raised surfaces. Parametric Features: Make the following parameters adjustable: • Overall dimensions and seating height. • S-curve control points and curvature. • Number, thickness, and spacing of wooden ribs. • Cushion dimensions and positioning. CAD Requirements: • Generate actual editable solid/NURBS geometry, not just a rendered image or static mesh. • Keep wooden ribs and cushions as separate editable objects. • Use millimeters. • Ensure geometric accuracy, smooth transitions, and clean geometry. • Preserve the original organic sculptural design without simplifying it. Final Output: A complete, detailed, parametric 3D CAD model with realistic oak ribs and two integrated ivory cushions, ready for further editing and development in Rhino 3D.
