Drawing 2D markup in the model view

Use the Add Markup  tools to draw arrows, circles, and ellipses in the viewing area. When you save the markup, a snapshot is automatically created that includes your markup  and an optional comment . These are private in your model file. However, you can easily share this information with others by adding the snapshot with your markup to a story. All collaborators with access to the story can see your markup and respond with their own comments.
