A cross section slices through objects showing a flat surface, or cap, across all objects. The sectioning tools cap all cross sections by default. Uncapping cross sections shows objects as if they were hollow.
ImportantSaving to My Views retains display changes, such as cross sections, field of view, layers, lighting, and 3D object movements and rotations.
