Depending on the complexity
of the system or application that you are modeling, you might choose
to create a single model or several models. You can create empty models
or use an existing model or model template as a starting point.
Before you begin
You must have a project in order
to create a UML model. To create a project, click and choose a type of project. You can add a UML model
to any type of project, but the Model project is the default type
for UML modeling.
About this task
The
IBM® Rational® Software Architect Designer provide
several templates that you can use to create content for particular
types of model. When you create a UML model from a template, the new
model contains diagrams and elements from the template, which you
can then edit or add to. Models created from templates also inherit
other settings from the template, such as which capabilities are enabled
for that model. The templates that are available depend on the features
that you installed and the capabilities that are enabled in the workbench.
Similarly,
you can create a new model using an existing model as a template.
In this case, the elements, diagrams, and capabilities are copied
from the existing model into the new model.
Procedure
- From the Modeling perspective, click .
- In the Model wizard, on the Create
Model page, click Standard template to create
the model from a template (including the blank template for an empty
model), or click Existing model to create the
model from a model in your workspace.
- Click Next.
- If you are creating the model from an existing model, select
that model in the Select a model file field,
give the new model a name and location, and click Finish.
- If you are creating the model from a template, follow these
steps:
- Under Categories, select a category
of template.
- Under Templates, select the template
to use. If you want to start with an empty model, select
the General category and the Blank
Package template. If you don't see the template you want
to use, select the Show All Templates check
box to show templates that are hidden because their capabilities are
disabled.
- Give the new model a name and a location.
- Click Next.
Note: The
wizard that you use to create a model from a template contains several
pages; the pages differ depending on the type of model template that
you select. For example, you can only specify default diagrams or
referenced projects for certain templates.
- Depending on the template, fill in the information on
the next page or pages of the wizard. You may need to select
the type for the default diagram, the capabilities to associate with
the model, the type of package to create in the model, or whether
to add the model to a working set.
- Click Finish.
Results
The new model is added to the selected project and is displayed
in the
Project Explorer view. Some templates
include instructions, which are displayed in the diagram editor when
the new model opens.
