The Spread component is based on a set of underlying models: classes that provide most of the features for the component. You can work directly with these models, or you can work with the Spread Designer or shortcut objects. When you perform tasks using the Spread Designer or shortcut objects, the tasks actually affect the models themselves.

If you want to provide extensive customizations for the component, increase efficiency, or create a template to use within your workgroup, you will probably want to customize the Spread models.

Consult the following topics for lists of the Spread models and more information about the model classes.
