To create a story for your model, you begin by placing a storytelling button on the Interface layer of your model.
Once you've placed the storytelling button, you build the story in the Create Story dialog box by selecting the model elements you want to include in the story.
You can then refine the story by testing and editing it (by adding, removing, reordering, and regrouping elements) until it's ready to distribute to model users.
