The prompt
Act as an automotive chassis engineer. Design a fully parametric CAD model of a watertight amphibious lower hull for an electric extreme off-road vehicle. The hull is the primary structural enclosure but only semi-structural, with steel drive modules attached through structural nodes. Overall Hull Dimensions Length: 2200 mm Width: 1350 mm Overall Height: 720 mm Material: Marine Grade Aluminium 5083-H116 Outer Skin Thickness: 6 mm Inner Skin Thickness: 5 mm Double Wall Gap: 80 mm Construction: Fully TIG welded Waterproof Double wall Include: Front bulkhead Rear bulkhead Three internal transverse bulkheads One central longitudinal reinforcement Continuous weld flanges Drain plugs Inspection covers Battery mounting surfaces The hull floor must include a raised central keel. Keel Dimensions Length: 2200 mm Width: 500 mm Height: 150 mm Lowest ground clearance: 600 mm Both front and rear ends taper upward by 30 degrees. The hull side walls should incline outward by 8 degrees. Corner radii: 25 mm internal 40 mm external Generate separate bodies for: Outer hull Inner hull Bulkheads Keel Mounting flanges Export as a fully parametric assembly.
