The prompt

Create a fully parametric 3D CAD assembly of a Firefighting Quadcopter Drone with a 10-liter rectangular water tank. Include a carbon fiber X-frame (1200 mm motor-to-motor), four brushless motors with 30-inch propellers, 10 L HDPE rectangular tank (250 × 200 × 200 mm), high-pressure diaphragm water pump (120 × 70 × 80 mm), spray nozzle with solenoid valve, battery tray, flight controller mount, GPS mast, electronics box, landing gear (300 mm height), hose routing, and all mounting brackets. Generate the complete assembly, exploded view, disassembly sequence, Bill of Materials (BOM), and dimensioned engineering drawings with standard M3/M4/M5 fasteners. Ensure a balanced center of gravity, modular construction, realistic clearances, and compatibility with STEP, STL, Fusion 360, and SolidWorks formats.
