The prompt
Create a simplified, editable 3D CAD model of my actual three-wheeled Super Mileage Vehicle steering system using the uploaded reference images. Include ONLY: the relevant tubular chassis frame, rack-and-pinion mechanism, pinion shaft, rack supports, tie rods, and their joints. Frame: Preserve the real chassis layout and tube orientations. Follow the red-highlighted frame orientations in the annotated reference. Do not mirror, rotate, or distort the geometry. Steering: Keep the rack-and-pinion gear mesh OPEN and clearly visible, with sufficient space around the rack. Model the tie rods in the correct orientation, following the real photographs and highlighted reference. Remove: Unnecessary plates, interior structures, wiring, pedals, batteries, and unrelated components. Retain essential frame members and steering mounts. Use separate components, realistic connections, editable dimensions, and suitable joints for future motion simulation. Avoid intersections and unnecessary details. Use actual dimensions only when provided; otherwise, keep dimensions adjustable and mark them as provisional. Do not invent precise measurements or redesign the mechanism. Priority: Accurate orientation, visible rack-and-pinion, correctly routed tie rods, simplified frame, and simulation-ready assembly.
