Add New Attribute

The creation of the attribute classification system establishes an easier way to add new attributes without having to perform major code revisions.

属性分类系统的创建，建立了一个不用对代码进行大的修订就可以添加新属性的简便方法。

If you add a new attribute or edit an existing one, an attribute editor appears, as shown in Figure 15.

如果添加新需求或编辑现有需求，就会出现属性编辑器，如图15所示。

Create a new preference variable in the Add Attribute dialog, as shown in Figure 48.

在Add Attribute对话框中创建一个新的偏好，如图48所示。
