Swept handle

The request

Make a grab handle: one smooth arched bar with a round cross-section about 12mm in diameter, sweeping in a continuous arc that spans 100mm from one end to the other and rises about 25mm at its midpoint. No sharp corners along the bar. Model it as a single sub-part named `handle`.

What the AI judge checks

• One continuous bar, not a chain of visibly separate cylinders or a stack of primitives
• The bar follows an arch from one end to the other rather than running straight
• The bar's cross-section is round, not square or rectangular
• The arc is smooth along its whole length, with no kinks or straight segments where the curve changes direction
• The bar keeps the same thickness from end to end, without bulges or pinched sections
• The high point of the arch is at the middle of the span, not pushed toward one end

Measured checks

• watertight (gate)
• spans the requested envelope
• slender arched bar, not a filled block
• smoothly curved surfaces (not a faceted block)
