The prompt
The assembly must contain the following components: Main rectangular structural frame with four vertical corner posts and horizontal connecting rails. Front, rear, left and right enclosure panels. Internal air-stream separation partition. Large circular rotary enthalpy wheel positioned centrally inside the enclosure. Central cylindrical hub. Twelve equally spaced radial spokes connecting the hub to the wheel structure. Main 25 mm diameter rotating shaft. Two shaft bearing housings. Electric drive motor mounted on a separate motor platform. Motor body, end cap and output shaft. Motor drive pulley and wheel drive pulley. Engineering dimensions: Overall bounding envelope: approximately 1760 × 1110 × 2200 mm. Structural corner posts: 40 × 40 × 2100 mm. Main shaft diameter: 25 mm. Radial spokes: 12, equally distributed at 30-degree intervals. Design requirements: Use millimetres. Keep the components geometrically separate wherever practical. Maintain concentric alignment between the wheel, hub and shaft. Ensure the wheel is supported by the bearing housings. Position the motor and pulleys to represent a belt-driven rotary wheel. Use realistic mechanical proportions and a professional industrial HVAC appearance. Create solid B-rep geometry, not a visual-only mesh. Use editable parameters for dimensions. Organize the model as an assembly with clearly identifiable components.
