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® modeling products 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.
