Defining classes

Adding an attribute to a class

An attribute is a named property of an object that defines the characteristics of the object.

You can add attributes that already exist in the model and which belong to other objects.

ϖTo add an attribute to a class:

1Double-click a class in the model. The class property sheet appears.

2Click the Attributes tab. The Attributes page appears.

3 Click the Add Attributes tool.
