A project allows you to group together all the models and other types of documents you need for a particular modeling task, and save them as a simple entity in your repository.
A project can contain one or more project diagrams (see Project Diagrams), which show the connections between models and other documents:
Your project can also contain one or more framework diagrams and/or a framework matrix, which direct how your project must be modeled and list the documents that are needed (see Completing Framework Diagrams and Matrices).
You can create a project from scratch or from a template. PowerDesigner provides a set of predefined project templates, and you can also create your own (see Project Templates).
