The Find in Diagram feature can be very useful if you are looking for the target object of shortcut symbols, as you can access the target object from the shortcut property sheet and then use the Find in Diagram feature to locate the target object in the diagram.
The Find in Diagram feature is available from:
♦The Browser
♦The Result List
♦The object property sheet dropdown menu
♦An objects list

You can use packages to build a multi-level structure within your model. In each level of the hierarchy, you can create diagrams in order to manage different views of the model objects.
PowerDesigner offers two features to help you navigate among the hierarchy of diagrams within a model:
♦The diagram tree shows the list of diagrams of the current model
♦The navigation listbox in the toolbar

A diagram is a view of the objects belonging to a model or to a package.
To add a symbol to a diagram you have to create a new object in the model or package to which the diagram belongs, the associated symbol appears in the diagram window.

Diagrams are saved with the model. When you save a model, you save the page scale parameters defined for each diagram.
You cannot save a diagram individually.
For more information on saving a model, see section Saving a model.

When a package begins to reach a critical size, it is useful to reorganize it into sub-packages using diagrams.
PowerDesigner lets you convert a diagram to a package using the Convert Diagram to Package Wizard from the Tools menu. You can replace the existing diagram with a new sub-package in order to simplify the source diagram. This process moves the diagram and the objects it contains from its source package to a new sub-package. The diagram must contain objects to proceed to the conversion in the wizard.
When you convert a diagram to a package, object symbols of the diagram are always moved to the package ; the objects themselves are either moved or replaced by a shortcut.
The linking objects that you move keep their links in the target package and a shortcut is usually created in the source package. The general rule being that conceptual modeling must be preserved.
Shortcuts creation rules in PowerDesigner also apply to moving objects between packages.
For more information on shortcut creation, see chapter Managing shortcuts.
PowerDesigner lets you select the objects of the diagram you want to convert to a package using the Show Symbols dialog box. Only relevant tabs are displayed. For example, if you convert to package a diagram that only contains tables and references, only the Table tab will be available, as the reference is contained in the table definition. Besides, when you deselect two objects related with an oriented link, the link is automatically deselected (for example two classes with an association link or two entities with a relation link). Just as when you deselect a non oriented link, ending objects are automatically deselected.

In the case of synchronized models (CDM and PDM) migrated from version 6, you need to convert both the CDM diagram and the PDM diagram into packages in order to preserve the changes made to the PDM.

By default, PowerDesigner 6 submodels are opened as diagrams in |
|
PowerDesigner. |
|
You can afterwards convert diagrams to packages. |
|
For more information on converting diagrams to packages, see section |
|
Converting a diagram to a package. |
Synchronize |
When you want to keep V6 conceptual and physical models synchronized, |
CDM/PDM |
you have to migrate both models. This converts V6 submodels into diagrams. |
|
For more information on the CDM and PDM migration, see section |
|
Migrating models from version 6 in the 3'0 8VHU V *XLGH. |
|
If you want to convert diagrams to packages in the models, you only have to |
|
convert the CDM diagrams to package, the generated PDM will be |
|
automatically updated and the packages will be created. |

PowerDesigner allows you to interchange Unified Modeling Language (UML) models between different UML tool vendors using the XML Metadata Interchange (XMI) standard file format.
XMI combines the benefits of web-based XML standard for defining, validating and sharing document formats on the Web with the benefits of the object-oriented UML. However, the current version of XMI does not support diagrams interchange.
Using XML to transmit data gives the advantage that data can be interchanged regardless of platforms.
PowerDesigner allows you not only to import XMI files so that you can use models created in collaborative modeling environments, but also allows you to export them as XMI files so that any partner can use them.
The current version of XMI is 1.1 and PowerDesigner uses the UML 1.3
DTD to generate XMI files.
When you import an XMI file in PowerDesigner, you must select an object language and the first diagram, in which you want to open the XMI file. When you export an XMI file, you save your Object-Oriented Model (OOM) under the XML format.
,PSRUWLQJ ;0, ILOHV
When you import an XMI file, you have to choose an object language and the diagram to open (class or use case). You can then select the .XML file to import.
The corresponding OOM appears in the diagram window. By default all symbols are visible in the diagram window.
ϖ7R LPSRUW ;0, ILOHV
1Select File→Import→XMI File.
The New Object-Oriented Model dialog box appears.
For more information on object language properties, see chapter Generating for a language in the 220 8VHU V *XLGH.
2Select an object language from the Object Language dropdown listbox.
3Select either Share or Copy.

When you export an XMI file, you save your OOM under the XML format.
Your file can then be interchanged regardless of platforms. However symbols will be lost as only objects are exported.

The General page in the Output window, located in the lower part of the PowerDesigner main window, shows the objects export order. Your OOM is now an XMI file that you can, for example, easily share with vendors of UML modeling tools or code generator like Java, Corba or C++.
