Prompt
Create a precise parametric 3D CAD model of a straight-fin aluminum heatsink with exact engineering dimensions. The model must follow these constraints strictly and numerically. Overall dimensions: Width: 40 mm Depth: 40 mm Total height: 15 mm Base: Thickness: 4 mm Solid rectangular block Size: 40 mm × 40 mm × 4 mm Fins: Quantity: EXACTLY 20 fins (not 19, not 21) Fin height: 11 mm (measured from top surface of base) Fin thickness: 0.8 mm Fin depth: full 40 mm Orientation: fins run parallel along the depth (40 mm direction) Spacing: Fin-to-fin spacing: 1.2 mm clear gap between each adjacent fin Total pitch (center-to-center): 2.0 mm Number of gaps: 19 Total fin width: 20 × 0.8 mm = 16 mm Total gap width: 19 × 1.2 mm = 22.8 mm Combined occupied width: 38.8 mm Remaining margin: 1.2 mm total Left margin: 0.6 mm Right margin: 0.6 mm Placement: First fin starts 0.6 mm from left edge Fins distributed using exact linear array with 2.0 mm pitch Last fin must end 0.6 mm before right edge Material: Brushed aluminum (Aluminum 6063 appearance) Realistic metallic shading Machined edges slightly sharp (no rounded fillets) Rendering: Clean neutral studio background Technical CAD-style lighting Show perspective isometric view No extra fins Do not approximate fin count Maintain strict dimensional accuracy Use linear array with 20 instances and 2.0 mm spacing.
