In geometry, a cross section is the intersection of a body in 3-dimensional space with a plane, or of a body in 2-dimensional space with a line, etc. More plainly, when cutting an object into slices one gets many parallel cross sections.
With Computed axial tomography, computers construct cross sections with from x-ray data.
A cross section is a common method of depicting the internal arrangement of a 3-dimensional object in two dimensions. It is often used in technical drawing and is traditionally crosshatched. The style of crosshatching indicates the type of material the section passes through.
