BAJA SAEINDIA 2026 mBAJA Roll Cage

Generate a fully parametric 3D CAD model of a BAJA SAEINDIA 2026 compliant mBAJA roll cage for a single-seat 4WD ATV. The design must strictly follow the BAJA SAEINDIA 2026 Rulebook (Article B.3 Roll Cage, B.3.3 Driver Clearance, B.14 Ergonomic Requirements, and all mandatory roll cage member requirements). Driver Package: Driver height: 1830 mm (6 ft) Driver weight: 95–100 kg Include a realistic 95th-percentile digital human model seated in driving position. Driving posture should include hands on steering wheel and feet on pedals. Helmeted head, shoulder, knee, elbow, and foot positions must satisfy all BAJA clearance requirements. Ensure easy ingress and egress. Roll Cage Requirements: Primary material: AISI 4130 Chromoly Steel Primary members: 29.2 mm OD × 1.65 mm wall Secondary members: 25.4 mm OD × 1.20 mm wall Use smooth bends with realistic bend radii suitable for tube bending. No member interference or impossible weld joints. Maintain full structural triangulation. Include all mandatory BAJA roll cage members: Front Hoop, Main Hoop, Front Bracing Members, Rear Bracing Members, Side Impact Members, Shoulder Support, Lateral Cross Members, Roll Hoop Overhead Members, and all required diagonal bracing. Packaging: Steering wheel diameter: approximately 300 mm Seat inclination: 15–20° Helmet clearance above driver according to BAJA rules. Adequate clearance for knees, shoulders, elbows, pedals, steering, and firewall. Space reserved for engine, CVT, differential, suspension mounting, steering rack, fuel tank, and drivetrain. Design Goals: Lightweight but highly rigid. Manufacturing-friendly tube layout. Symmetrical left and right sides. Optimized for finite element analysis. Suitable for SolidWorks weldments. Output Requirements: Fully constrained 3D CAD model. Individual tube centerlines. Weldment feature tree. Tube cut list. Accurate tube lengths. STEP (.stp), Parasolid (.x_t), and SolidWorks (.SLDPRT/.SLDASM) compatible geometry. Include front, side, top, and isometric views. Dimension the overall wheelbase envelope and cockpit dimensions. Ensure the model is inspection-ready for BAJA SAEINDIA 2026 technical evaluation and follows good engineering practices.
