The prompt
Create a precision CAD model of a small axial-flow aircraft turbojet engine assembly, approximately 1000 mm long and 300 mm in diameter. Use simple, valid mechanical geometry. Include: - One long central cylindrical shaft. - One front compressor rotor disc with 8 simplified blades. - One rear turbine rotor disc with 8 simplified blades. - One cylindrical combustion chamber between the compressor and turbine. - One outer cylindrical engine casing. - One rear exhaust nozzle. Align all components along the same longitudinal axis. Keep the geometry simple and use separate solid bodies wherever supported. Make the model suitable for STEP export and import into Ansys Discovery. Generate a valid precision model with editable parameters. Prioritize successful model generation over fine details.
