Setting the SceneView View Angle/Position?

Hey there,

A very late answer, but I was looking for something similar myself. Now I've found it I'll share the solution so someone else might find it and benefit from it.

In my case I wanted the gameObject to stay selected while holding down CTRL/Control and even though I left clicked in different places in the sceneview, I also wanted to go into my "edit" mode while holding down CTRL.

     private void OnSceneGUI()
     {
         Event e = Event.current;
 
         // We're holding down CTRL
         if (e.control)
         {
             // Used to change inspectorGUI
             _holdingControlDown = true;
 
             // Makes sure to save the current camera position, rotation and orthographic setting
             if(_cameraPositionBeforeEditMode == Vector3.zero)
             {
                 _cameraOrthoBeforeEditMode = SceneView.lastActiveSceneView.orthographic;
                 _cameraRotBeforeEditMode = SceneView.lastActiveSceneView.rotation;
                 _cameraPositionBeforeEditMode = SceneView.lastActiveSceneView.pivot;
 
                 Vector3 newPivot = new Vector3(
                     accessableGridRef.transform.position.x,
                     accessableGridRef.transform.position.y + 100f,
                     accessableGridRef.transform.position.z);
 
                 SceneView.lastActiveSceneView.pivot = newPivot;
             }
 
             // Removes the default "handle" from Unity's tools
             if (Tools.current != Tool.None)
             {
                 _lastTool = Tools.current;
                 Tools.current = Tool.None;
             }
 
             // If the user holds down ctrl while clicking with left mouse button
             if (e.isMouse && e.button == 0 && e.type == EventType.mouseDown)
             {
                 Debug.Log("Pressed left mouse button while holding ctrl");
 
                 // I'm going to change some stuff here later.
             }
 
             // Set camera to iso from top point
             SceneView.lastActiveSceneView.orthographic = true;
             SceneView.lastActiveSceneView.rotation = Quaternion.Euler(90, 0, 0);
             // You can also set position here by going:
             // SceneView.lastActiveSceneView.pivot = new Vector3();
 
             // Keep selection of Level, no matter what I click in the sceneView
             Selection.activeGameObject = accessableGridRef.gameObject;
 
             // If we let go of CTRL, remember to debrief everything and put stuff back to "normal"
             _debriefEditorMode = true;
         }
         else
         {
             // Resets everything back to the view it had before
             if (_debriefEditorMode)
             {
                 _holdingControlDown = false;
 
                 if (Tools.current == Tool.None)
                 {
                     Tools.current = _lastTool;
                 }
 
                 SceneView.lastActiveSceneView.rotation = _cameraRotBeforeEditMode;
                 SceneView.lastActiveSceneView.orthographic = _cameraOrthoBeforeEditMode;
                 SceneView.lastActiveSceneView.pivot = _cameraPositionBeforeEditMode;
 
                 _cameraPositionBeforeEditMode = Vector3.zero;
                 SceneView.lastActiveSceneView.Repaint();
 
                 _debriefEditorMode = false;
             }
         }
     }
