Render GameObject in editorWidnow & How to hide these Objects in Scene and Game window?

1. Use PreviewRenderUtility draw some object in EditorWindow. But I want to these object hide in Scene or Game Window.

2. Btw I need to selected Object in EditorWindow Use Physics.Raycast API. So I can't Delete GameObject.

What's the best way to render a Mesh in an Editorwindow? How do I solve the problems I'm having? I'm appreciated that someone can help me out! SOS!!!

Here some code below:

 private PreviewRenderUtility renderer;
 
 private void InitRenderUtility(){
     renderer = new PreviewRenderUtility();
     renderer.m_Camera.nearClipPlane = 0.3f;
     renderer.m_Camera.farClipPlane = 1000f;
     renderer.m_Camera.transform.position = new Vector3(0, 0, -10);
     renderer.m_Camera.clearFlags = CameraClearFlags.Depth;
     renderer.m_Camera.depth = -1;
     renderer.m_Camera.orthographic = true;
 }
 
 public void OnGUI(){
     renderer.BeginPreview(frameViewRect, GUIStyle.none);
 
     GameObject obj = CreateSomeObject();
     var objMesh = obj.GetComponent<MeshFilter>().sharedMesh;
     var objMat = obj.GetComponent<MeshRenderer>().sharedMaterial;
 
     Matrix4x4 m = Matrix4x4.TRS(Vector3.zero, Quaternion.identity, Vector3.one);
     renderer.DrawMesh(objMesh, m, objMat, 0);
 
     renderer.m_Camera.Render();
     var tex = renderer.EndPreview();
     GUI.DrawTexture(frameViewRect, tex);
 }
 
 private GameObject CreateSomeObject(){
     GameObject obj = EditorUtility.CreateGameObjectWithHideFlags(name, HideFlags.HideAndDontSave, 
     new System.Type[] {typeof(MeshRenderer),typeof(MeshFilter)});
 
     MeshFilter filter = obj.GetComponent<MeshFilter> ();
     MeshRenderer render = obj.GetComponent<MeshRenderer> ();
     MeshCollider collider = obj.AddComponent<MeshCollider>();
     render.material = new Material(someMaterial);
 
     Mesh mesh = new Mesh ();
     mesh.hideFlags = HideFlags.HideAndDontSave;
 
     mesh.vertices = newVertices;
     mesh.uv = newUV;
     mesh.triangles = meshTriangles;
 
     filter.sharedMesh = mesh;
     collider.sharedMesh = mesh;
 
     return obj;
 }
