F4.5.5} Orientation Cube
The orientation cube is the cube showing the axes system located on
the bottom-left corner of each viewport
Hovering the mouse over the cube, it will enlarge in size and show
more detail waiting for mouse click commands
The letter on each side corresponds to the name of the side.
The naming follows the coordinate conversion that:
Z is horizontal and points the beam direction
Y is vertical (anti-gravity)
X is the horizontal (cross product of YxZ)
Letter Name Side description

F Front X-Y plane towards the positive Z
B Back X-Y plane towards the negative Z
U Up X-Z plane towards the positive Y
D Down X-Z plane towards the negative Y
L Left Y-Z plane towards the positive X
R Right Y-Z plane towards the negative Y
