| **3D Placement Mode**                                               | Sets where newly created 3D objects are placed in the scene. The following options are available:**World Origin**: Instantiates new 3D objects at world coordinates `0, 0, 0`.**Scene Intersection**: Instantiates new 3D objects at the nearest collider in the center of the **Scene** view. If no collider is hit, the 3D object is instantiated at the [`SceneView.pivot`](/engine/6000.5/script-reference/unityeditor/sceneview/pivot.md).**Scene Pivot**: Instantiates new 3D objects at the [`SceneView.pivot`](/engine/6000.5/script-reference/unityeditor/sceneview/pivot.md). |
| **Use prefab asset position when dropping on the Hierarchy window** | Places prefabs added to a scene through the **Hierarchy** window at the transform position value they were saved with. When disabled, prefabs are placed according to the **3D Placement Mode** setting. This setting is disabled by default.                                                                                                                                                                                                                                                                                                                                           |
| **Create Objects with Constrained Proportions scale on**            | Defines the default behavior for **Scale** in the [Transform](/engine/6000.5/manual/working-with-gameobjects/gameobject-fundamentals/class-transform.md) component. When enabled, changing a GameObject's scale on any axis changes the other axes by the same amount. You can disable and enable this option for individual GameObjects in the **Inspector** window.                                                                                                                                                                                                                   |
