Software Architect and Systems Developer combine the visual modeling aspect of Rational XDE with the advantages of visual editing and transformations, while Software Modeler provides stand-alone UML 2.0 modeling. The XDE Import help topics refer to both Software Architect, Software Modeler and Systems Developer as Rational UML modeling products. While most of the help topics apply each product, several topics that discuss visual editing and transformations only apply to the Software Architect and Systems Developer products.
