You can create any of the model types supported by PowerDesigner from within Visual Studio. The following procedure focuses on how to create an object-oriented model (OOM).
New model – Creates a new, standard, model.
New model from template – Creates a model from a model template, which can contain pre-configured options, preferences, extensions, and objects. For more information, see Model Templates.
Object languages are defined in dedicated XML files (with a .XOL extension), which are provided as part of your PowerDesigner installation in the "\Resource Files\Object Languages" directory, and contain all the syntax and specifications for each target language.
By default, PowerDesigner creates a link in the model to the specified file. To copy the contents of the resource and save it in your model file, click the Embed Resource in Model button to the right of this field. Embedding a file in this way enables you to make changes specific to your model without affecting any other models that reference the shared resource.
You can create as many diagrams as you need in the same OOM. They are sorted alphabetically in the Model Explorer, except the diagram specified here, which is always the first in the list.
