The prompt
Create a conceptual tubular space-frame chassis for a small 4-wheel electric vehicle with 4 seats arranged in 2 rows of 2 seats. Chassis requirements: - 4 wheels - 4 occupants - Tubular space-frame structure - Steel hollow tubes - Welded tube construction - Approximate overall length: 3200 mm - Approximate overall width: 1600 mm - Approximate chassis height: 1200 mm - Wheelbase: approximately 2200 mm - Front and rear axle structures - Two longitudinal main rails on each side - Transverse cross-members connecting the two sides - Diagonal tubes for structural reinforcement - Reinforced front and rear sections - Reinforced side sections around the passenger compartment - Flat and rigid floor frame - Two rows of seats, 2 seats per row - Provide mounting points for the seats - Provide basic suspension mounting areas near the four wheels - Keep the design symmetrical around the longitudinal centerline Important: Generate ONLY the tubular chassis frame. Do NOT include the vehicle body, doors, windshield, roof panels, wheels, motors, battery, seats or interior components. The result should look like a realistic engineering concept of a welded steel tubular space-frame chassis suitable for a university electric vehicle project. Use simple, manufacturable tube geometry with realistic welded joints. Make the model editable and exportable as STEP
