Extending Your Modeling Environment with Extended Model Definitions

Extended model definitions (.XEM files) allow you to customize and extend PowerDesigner metaclasses, parameters and generation.

You can do this when creating a new model by clicking the Select Extensions button at the bottom of the New Model dialog, or at any time by selecting Model > Extended Model Definitions to open the List of Extended Model Definitions and clicking the Import an Extended Model Definition tool.

In each case, you arrive at the Select Extensions dialog, which lists the extensions available, sorted on sub-tabs, which depend on the type of model you are working with:
