To display the cut section of your model, you activate a view cut and choose whether to display the model on the cut, below the cut, and/or above the cut. The cut itself is not visible. Only one view cut can be active at a time.
To display a cut section:
From the main menu bar, select Tools
View CutManager.
The View Cut Manager appears with a list of all the view cuts that have been created during the current session. A check mark appears in the Show column to the left of the active view cut.
Click the check box in the Show column to the left of the view cut you wish to activate or deactivate.
The active view cut is used to cut through the model in the current viewport.
Tip:
You can also activate or deactivate a view cut using the 
tool in the toolbox. If no view cut is active, selecting this tool will activate the first view cut in the list in the View Cut Manager (usually the default X-plane cut). If a view cut is active, selecting this tool will deactivate the cut.
Click the check boxes in the Model columns to the right of the view cut to display the model below 
, on 
, and/or above 
the cut (these positions are not mutually exclusive).
The selected portion of the model is displayed in the viewport.
