When you add a 3D Text node to your Action schematic, a special geometry node with an axis is added.
To add a 3D Text node to the scene:
Do one of the following:
A Geometry object, called Text1 by default, and parent axis appear in the schematic. In Result view, the default Text string appears.
To open the 3D Text menu, double-click the 3D Text node in the schematic, or follow the tab population rules for the Object menu.
You can also add a 3D Text node using the Presets node. See Using 3D Text Presets.
