How to remove part of a model in threeJS?

Question

JavaScript

On the stage I have a model, it is initialized and added to the stage like this.

var loader = new THREE.FBXLoader();
loader.load( 'data/nameOfModel.FBX', function ( object ) {
  model = object;
  model.name = 'lighter';
  scene.add( model );
} );

Here is the structure of the scene in the debugger:

You need to remove "10_30_60".
Tried Didn't work. Please tell me how can I check this. It is still advisable to delete by name, because. the model will have many such parts.
scene.remove(scene.getObjectByName('10_30_60'));

Answer 1

Is it useful to anyone

function clearScene(object) {
  while(scene.children.length > 2){ 
    scene.remove(scene.children[2]); 
  }
}

This clears the entire scene.
