The Z-Axis is a common item in 3D applications. It is one of the axes in a three dimensional system that gives things a 3D perspective. Now PowerPoint has some z-axis features, which Microsoft refers to as ‘3D Rotation.’ All three of these text boxes were created from the same one. The top one shows the visual effect applied to the text (bevel and reflection). The bottom two apply 3D Rotation for some GREAT Visual effects!
And all of these remain editable text.
