Make sure model always keep the same height at the same position

I’m kindly new to this stuff,

How can I make sure that the object has always the same width and height of the model without being scaled due resizing? How can i zoom out more?

I want to start rotating the object automatic, not sure if I should do that here or with the use of GSAP

You can move the camera back further.

camera.position.set( 0, 0, 10 );

This should keep it in frame vertically… (it won’t horizontally tho.)
