3D Text: An activation checkbox that, when selected, applies 3D attributes to selected text in your project and enables 3D controls in the Appearance pane. Deselecting this checkbox converts selected 3D text to flat 2D text and disables 3D controls in the Appearance pane.
When this checkbox is selected, the following controls become available for adjustment:
Depth: A slider that sets the thickness of selected 3D text.
Depth Direction: A pop-up menu that sets whether selected 3D text is extruded backward, forward, or equally from front to back.
Weight: A slider that makes selected 3D text appear heavier or lighter.
Front Edge: A pop-up menu that sets the style of the front edge of selected 3D text.
Front Edge Size: A slider that adjusts the width and depth of the chosen edge style. Click the disclosure triangle to reveal separate Width and Depth sliders.
Back Edge: A pop-up menu that sets the style of the back edge of selected 3D text.
Inside Corners: A pop-up menu that sets the style of the inner corners of the front and back edges (such as angles in the letter E) in selected 3D text. The Front Edge or Back Edge of a text object must be set to an option other than Square to see the affect of this parameter.
