A UML use case with PowerDesigner

Once I had a new task: to create Use case diagram, and I found a program PowerDesigner. This took for me a couple of hours and now I give you a tutorial!

I should notice, that I don’t know a manufacturer of this program and it has free trial period of 30 days.

How to create Use case diagram in PowerDesigner.

1.     Download program and launch it. While installation choose appropriate language.

2.     Create a new model: go to tab "File" and choose "Use Cases Definition".

3.     Now a new workspace is opened. To the right you can find Toolbox (we are interested in group “Use case diagram”), and to the left – structure of workspace with the objects.

4. For diagram element creation you can use Toolbox or choose one on the "Model" tab.

5. After you finished to drawing an element, you should to switch pointer to “Object selector”.

6. If you need to create a relation between elements, you can use Toolbox or choose one the "Model" tab.

7. If you go to the "Model" tab, then a window of a new relation is opened. If you use another way and want to modify relation, then just double-click on relation line.

For displaying a type of relation under its line, you should to fill the field “Stereotype”.

8. More diagram elements can be found through tab “Model”.

Following these steps, you can create Use case diagram. If you want to share your experience in diagram creation field, then leave a comment! It would be very interesting and useful!
