Create New Elements on a Diagram
Models are constructed from elements, each of which has its own meaning, rules and notation. Generally, when you create a new element in your model you want to use that element on a diagram. The simplest way to do this is to create the element directly on the diagram. In this procedure, we will use a Requirement element as the example.
