Error creating thumbnail: Unable to save thumbnail to destination	Error creating thumbnail: Unable to save thumbnail to destination	Extension point	Node	Create an extension point in a use case to specify a point in the behavior of a use case, where this behavior can be extended by the behavior of some other use case. That is, an extension point refers to a location within a use case where you can insert action sequences from other use cases. The Extension point element is available on the context menu of a use case, in the Diagram View and Model View. See Creating an Extension Point. An extension point consists of: A unique extension point name within the Extension Points compartment in the use case. In the picture, this is the set priority extension point in the compartment of the base Use Case use case. An extend relationship (dependency link), stereotyped as <<extend>>, to the use case that extends the behavior of the first use case. In the picture, this dependency link has the (set priority) label and the extension use case has the name managing priorities.
