The prompt

Create a modern L-shaped sectional sofa base frame using millimeters. Overall dimensions: - Total width: 2800 mm - Total depth: 1800 mm - Base height: 180 mm Configuration: - Main sofa section: 2800 mm wide and 900 mm deep. - Right chaise lounge section: 900 mm wide, extending the total depth to 1800 mm. - The chaise must be on the RIGHT when viewing the sofa from the front. - Create a precise L-shaped footprint using two connected rectangular solid platforms. - Keep the top surface flat and level. - Use clean, straight modern geometry. - Slightly round all external edges with 10 mm radius. - No cushions, upholstery, legs or backrests yet. - Generate a solid, editable parametric CAD model.
