Working in 3D
In Maya software, you will build and animate objects in three dimensions. These dimensions are defined by the cardinal axes that are labeled as X, Y, and Z. These represent the length (X), height (Y), and depth (Z) of your scene. These axes are represented by colors—red for X, green for Y, and blue for Z.
The cardinal axes
The Maya default has the Y-axis pointing up (also referred to as Y-up).
As you position, scale, and rotate your objects, these three axes will serve as your main points of reference. The center of this coordinate system is called the origin and has a value of 0, 0, 0.
