Sections through a model can be created by using a Slicer or a "Clipper." Select one of the "Clipper" options available in the "Clipper" Settings section of the panel to activate it. The "Clipper - Plane" option displays the results of the zone behind (or in front of) the cutting plane. As an alternative, you can apply a "Clipper" - Box to examine the results on the surfaces of a box-shaped cutout.
The settings options of the "Clipper" tab correspond to those of the "Slicer". You can modify the clipper plane graphically via one of the four bullets shown in the corners of the section plane. When you pull the clipper plane along a wind tunnel line, the results are updated dynamically.
