Use text boxes to display text in your model. You can use text boxes to add labels, instructions, and explanatory text right on the model diagram.
You can place text boxes on the Interface, Map, and Model layers.
Click the diagram to place the text box.
To specify properties for the text box, and to format the text inside the text box, select the text box and then double-click the text box border, or right-click the border and then choose Open from the menu that appears.
The Text Box properties appear in the Properties panel.
Note On the interface you can use html tags such as <a href="https://iseesystems.com">link</a> to embed content in plain text boxes (will not work with rich text).
