Use the Bevel curve to add a bevelled edge to your 3D text. Use the options in the Edit Mode box to add, select, delete, or move keyframes on the Bevel curve. The Bevel curve behaves in much the same way as an animation curve in the Channel Editor.
Experiment with different curves to create different effects.
You can save Bevel curve settings as well as font, character size, kerning, italics, and depth. See Saving, Loading, and Importing.
