Using the Gizmo

With the new 3D Scene Editor, the Gizmo has been added. This combines all manipulation of objects into one interface, which allows for easier and faster scene editing.
This tutorial aims to explain all features of the Gizmo, and will provide examples you can recreate to help you understand its application.
To start off, create a new DXStudio document, and add a new 3D Scene. Then, click the green plus button in the objects window, and go to add mesh. Select the ground_plane object. This will be added to the scene. Now, go to add mesh again and select chesspiece_rook_white. Again, this is added to the scene.
Select the chesspiece_rook_white you just added in the objects list. The Gizmo should appear in the 3D Scene (if it hasn't already). Click 'View Selection' - it's the bottommost monitor icon on the vertical toolbar next to the objects list.

You should now be focused on the chesspiece, and your screen should look something like the following:

The bars on the Gizmo which extend from the origin indicate what axis they represent. For reference, it is as follows:
Red : X
Blue : Z
Green : Y

Scaling

Now, you may have noticed that the Rook is quite small, and hard to see. To solve this, we can scale the model in 3 dimensions. Each dimension can be scaled individually, or the mesh can be scaled uniformly. The following image highlights the parts of the Gizmo that control scaling.

The areas highlighted above are:
1. Scale object in the Y dimension.
2. Scale object in the Z dimension.
3. Scale object in the X dimension.
4. Scale the object in all 3 dimensions.
Now, scale the Rook uniformly so it's bigger than it used to be. Do this by clicking on the ball at the origin (Number 4 in the image), and moving the mouse up.

Moving

Moving objects is probably the most common thing done when editing a 3D scene. The Gizmo allows a high degree of control over moving objects.
Using the Gizmo, objects can be moved along the X, Y and Z dimensions individually, or a combination of planes. These are X-Y, X-Z, Y-Z. The following image points out these areas.

The areas highlighted above are:
1. Move object along Y dimension.
2. Move object along X dimension.
3. Move object along Z dimension.
4. Move object along X-Y dimension.
5. Move object along Y-Z dimension.
6. Move object along X-Z dimension.
Play around with moving the Rook around, to get a feel for the Gizmo. If you lose it, you can always undo.

Rotation

The Gizmo lets you rotate objects in each dimension. The image below highlights important areas.

1. Rotate object around Y axis.
2. Rotate object around Z axis.
3. Rotate object around X axis.
