Adjust the display position of the Gearbox Assy model with the built-in camera

[cx20]

Currently, the Gearbox Assy model is not in the center of the scene, so some samples adjust the position of the model in code.
However, this model has a built-in camera and applying it seems to center the model's position.
If I have a built-in camera, I'd like to use that camera.
