The Structural Analysis Tools provide information about the structure of a model. These tools can be used without reference to datasets, although the Document tool has the option of displaying behavioral information. Because of this, you can use the Structural Analysis Tools before simulating a model.
To use these Analysis Tools, first select the variable you are interest in into the Workbench (using the Variable Selection Control in the Control Panel, or by double clicking on the variable name in a tool output window). Note that the Tree, Outline and Loops tools work only on the variable name and ignore all subscripts. The Document tool, depending on how it is configured, will make use of the information in the Subscript Control.
