title: Fix a furniture on the ground created on a button using ARCore
body: <p>I am trying to a furniture app using ARCore, then click on a button to create a new model and put on fix position on the ground. The main issue is the model is following me when I move from point to point:</p>
  
  <p>I tried to create anchor and put it on the ground but it's not working:</p>
  
  <pre><code>public void DuplicateObject()
  { 
      GameObject Cloud = GameObject.Find("Point Cloud");  
      //Vector3 CameraPosition = new Vector3(MainCamera.transform.position.x , 0 , MainCamera.transform.position.z + distance);
      Vector3 CameraPosition = new Vector3(MainCamera.transform.position.x, Cloud.transform.position.y , MainCamera.transform.position.z + distance );
  
      NewObject = GameObject.Instantiate(Gobject , transform.position , Quaternion.identity);
      NewObject.transform.position = MainCamera.transform.position + MainCamera.transform.forward * distance;
  
      Vector3 AnchorPos =  NewObject.transform.position;
      Pose pose = new Pose(AnchorPos, NewObject.transform.rotation);
      _anchor = Session.CreateAnchor(pose , null);
      //NewObject.transform.Rotate(0, 180, 0, Space.Self);
      NewObject.transform.Rotate(0, k_ModelRotation,0 , Space.Self);
      _anchor.transform.parent = Cloud.transform;
      NewObject.transform.parent = _anchor.transform;
  }
  </code></pre>
  
  <p>What I want to do is just fix the model in a specific position on the ground.  What's the correct (best) way to do that?</p>
