title: How to handle 3D object size and its position in ARKit
body: <p>I am facing difficulties with 3D object size and its x, y, z positioning. I added the 3D object to <code>sceneView</code>, but its size is too big. How do I reduce the 3D object size based on my requirement? Can anyone help me handle the 3D object's size and its x, y, z positioning?</p>
  <p>I am using Swift to code.</p>
