Eye Directions

The eye direction buttons allow you to quickly set the eye point to one of the coordinate axes, and back to three-dimensional space. The buttons are labeled X, Y, Z, and 3D. Each button sets the eye point to the corresponding view direction.

If you click at the same button twice, the viewing direction is changed to the opposite side, e.g., to negative X axis direction with the second clicking of the X button.

Whether the view direction is set to one of the axis, or to 3D, has a great impact on how 3D transformations work. See the TRANSF commands for further details.
