The prompt
Create a highly detailed 3D CAD model of a complete automotive drivetrain system. The assembly should include the following mechanical components: 1. Internal combustion engine with cylinder block, pistons, crankshaft, and flywheel. 2. Clutch assembly consisting of clutch disc, pressure plate, and release bearing. 3. Manual transmission gearbox with multiple gears, input shaft, output shaft, and synchronizer assemblies. 4. Driveshaft connecting the transmission to the differential. 5. Differential assembly with ring gear, pinion gear, spider gears, and axle shafts. 6. Front and rear axle shafts connected to the wheels. 7. Four vehicle wheels with brake disc assemblies. **Design requirements:** - Create a realistic mechanical 3D model with accurate proportions. - Use precise engineering geometry and mechanical relationships. - Model every major component as a separate CAD part. - Assemble all components into one complete drivetrain system. - Show the internal mechanical structures using a cutaway or exploded view. - Use realistic metallic materials, including steel, aluminum, and cast iron. - Clearly demonstrate the power transmission path from the engine to the wheels. - Include mechanical details such as bolts, bearings, gear teeth, shafts, and mounting brackets. **CAD presentation:** - Professional engineering visualization. - Isometric 3D perspective. - High-resolution rendering. - Neutral background. - Realistic mechanical textures. - Suitable for mechanical engineering education and technical presentations. The final result should look like a professional automotive engineering CAD assembly.
