Creating a system architecture diagram
 |
PTC introduced the System Architecture Diagram to cover the shortcomings of previous versions of UML for the real-time environment. Now that UML 2.0 has introduced the Composite Structure Diagram, the System Architecture Diagram is no longer required. As such, the System Architecture Diagram remains in Modeler for backward compatibility, but it will not be further developed in Modeler: for example, you cannot apply iconic Stereotypes to the System Architecture Diagram symbols.
We recommend that you now model your system architecture using Composite Structure Diagrams, in accordance with UML 2.0. To help you migrate your System Architecture Diagrams to Composite Structure Diagrams, Modeler includes the System Architecture Migration Utility.
For information about Composite Structure Diagrams, see
Composite structure diagram symbols.

You construct the System Architecture Diagram in the same way as you do other diagrams, by using the tab buttons to
add items to the diagram or drag items from the dictionary onto your System Architecture Diagram.
A System Architecture Diagram represents part of a System Architecture Model, which you can
construct in the dictionary and then represent on diagrams.
One high-level System Architecture Diagram also defines the System Scope Model. You drag items from the System Architecture Model folder in the Relationships pane to develop this model.
A System Architecture Diagram includes the following elements:
