The prompt
Modify ONLY the blade planform of the existing parametric propeller. The current blades look too much like wide paddles or leaves. I want the realistic blade outline of a commercial multirotor propeller, as shown in my reference image. **Required modifications:** - Maintain a nearly straight radial blade centerline. - Use smooth, gently asymmetric leading and trailing edges. - Gradually increase the blade chord from the root toward the middle span, then smoothly decrease it toward the tip. - Avoid sudden widening near the blade root. - Avoid exaggerated S-shaped curvature or sweeping. - Make the blade tips smoothly rounded, not pointed or flat-cut. - The blade should resemble a conventional drone propeller, not a leaf, paddle, or banana. **Chord distribution:** - Root (0%): 20 mm - 20% span: 27 mm - 40% span: 33 mm - 60% span: 34 mm - 80% span: 26 mm - 95% span: 15 mm - Tip: 8 mm Keep the original parametric sliders editable. **Do not change:** - Overall diameter: 300 mm - Number of blades: 2 (adjustable to 3 or 4) - Shaft bore diameter: 5 mm - Hub diameter: 20 mm - Hub height: 7 mm (preliminary) - Root pitch angle: 25° - Tip pitch angle: 10° Preserve identical blade geometry with equal angular spacing. Generate a valid STEP/STL solid model in millimeters for CAD visualization.
