The dimensions used in 3D CAD are often referenced as

Explanation:
In 3D CAD, dimensions are described using a three-axis coordinate system. The standard naming uses three perpendicular axes: X, Y, and Z. These axes provide directions along which points, lines, and features are measured, and they stay consistent across translations, rotations, and scaling. In most setups, X and Y define the plane you’re working in, and Z adds the height or depth, with a common right-hand rule that X cross Y equals Z. That’s why the standard answer uses X, Y, and Z as the axis names. The other options describe faces or views (like top/bottom or front/back) rather than the axis labels used to measure and locate geometry in 3D space.
