opened in the workspace. A reference allows you to reuse an
attribute with all its properties without having to define it
again. Use the dropdown listbox to select an attribute in the
current model. Use the Browse tool to select an attribute from
any model opened in the workspace. If you select an attribute
from another model, a shortcut is created with the referencing
attribute. When you define a reference, name and code
properties are grayed. The name and code are those of the
target attribute
