Three computations are not the same size as in blender

	new GLTFLoader()
	     .setPath( 'models/gltf/' )
	     .setDRACOLoader( new DRACOLoader().setDecoderPath( 'js/libs/draco/gltf/' ) )
	     .load( '11.glb', function ( gltf ) {
                 scene.add( gltf.scene );
                 const mesh = gltf.scene.children[ 0 ];
			     mesh.geometry.computeBoundingBox();
			    const size = new THREE.Box3().copy( mesh.geometry.boundingBox ).getSize( new THREE.Vector3() );
			   console.log( 'result--->', size );
                    } );


but in blender

how do i keep them equal?

They are equal. They only differ by a very small amount, caused by floating point rounding.

OK, thanks. I thought I was missing a step :joy:
