Can Rational XDE Developer be used to do free-form modeling?
Yes. As opposed to being just a free-form drawing tool like Microsoft Visio, or just a code visualization tool like Borland Together ControlCenter, Rational XDE Developer unites the strength of a semantically rich UML tool with the freedom and flexibility of customized diagramming using a variety of standard built-in shapes. Free-form designs within your model enable you to include comments and diagrams covering nonstandard UML items, or annotations clarifying your designs, without any constraints.
