The prompt
Modify the current parametric propeller CAD model to more closely match the blade geometry shown in the attached reference image. **IMPORTANT: Use the reference image as the primary guide for the blade outline and overall shape. Preserve the existing parametric functionality.** ### 1. Blade geometry modifications - Create realistic, smoothly curved, asymmetric blade outlines similar to the reference propeller. - The blade should be narrow near the hub, gradually widen toward the middle span, and smoothly taper toward the tip. - Use different smooth curvature profiles for the leading edge and trailing edge. - The maximum blade width should occur approximately 45–60% along the blade span. - Replace the current straight, flat-cut blade tips with smoothly rounded tips. - Avoid abrupt changes in blade width, sharp edges, and unnatural bulges. - Create a smooth transition between the central hub and blade roots. - Apply a gentle backward sweep, but avoid exaggerated S-shaped or excessively curved blades. - Use a smoothly twisted, cambered airfoil cross-section. ### 2. Fixed dimensions - Overall propeller diameter: 300 mm - Central hub diameter: 20 mm - Central hub height: 7 mm (preliminary) - Shaft bore diameter: 5 mm, cylindrical through-hole - Units: millimeters ### 3. Adjustable parameters Preserve or create editable sliders for: 1. Number of Blades: 2–4 2. Root Chord 3. Mid-span Chord 4. Tip Chord 5. Maximum Chord Position 6. Leading Edge Curvature 7. Trailing Edge Curvature 8. Backward Sweep Offset 9. Root Pitch Angle 10. Tip Pitch Angle 11. Root Thickness 12. Tip Thickness ### 4. Parametric requirements - All blades must have identical geometry and be evenly spaced around the central axis. - For two blades, maintain 180-degree rotational symmetry. - Changing the blade count must preserve the same individual blade geometry. - Maintain the overall 300 mm propeller diameter regardless of blade count. - Ensure smooth blade surfaces and continuous connections to the hub. - Generate a valid, closed solid model for STEP and STL export. - Keep all dimensions in millimeters. **The main objective is to match the realistic, curved, asymmetric blade shape of the reference image while retaining fully adjustable geometric parameters.** This model is intended for geometric comparison and CAD assembly visualization, not validated high-speed rotation.
