Controlling Reference Settings
There are a number of settings that control the attachment and display of references in a model. These can be controlled from the References dialog. The list box of the References dialog displays columns containing many settings that you can modify, either by just clicking them or by clicking them and selecting a new setting or value. Right-clicking on a reference entry opens a contextual menu with options for manipulating the reference (these same options also are included in the References dialog's Tools menu).
