Question Regarding Animating a 3D Model to Scale

I’m looking to animate a 3D model of a steam locomotive, and then create another model to 1/87 scale of the first, but am not sure of the best/easiest way of doing this. I would appreciate any and all help I can get in this regard. Thank you.

Hello, Synfig is a 2D software. You’ll have to use a 3D software to create your model.
