When you export to various formats, the <format type> Export dialogs lets you specify which project views and sheets to output. Use the following tools to create and select views and sheets to include in the output file. These selected views can be saved as a set for future use. 
- Export. Determines the set that will display in the View/Sheet list. This list contains all user-defined sets and the following default sets.
- <Current View/Sheet Only>. Displays the currently active view or sheet.
- <In session view/sheet set>. Enables Show in list, so that you can filter views and sheets for the entire project or established set.
- Show in list. Contains filters to broaden and narrow the available views and sheets of the selected set to output:
- Views in the Set
- Sheets in the Set
- All views and sheets in the Set
- Views in the Model
- Sheets in the Model

The model-based filters list views and sheets from the project, disregarding the chosen set. View and sheets are listed in alphabetical order.
