A cross sections, or, simply, section, or section view which diagram the sliced-

A section, or section view, or cross section is useful to make sure building layers are in the right order inside the surface of an elevation or a plan view.

perspective section

A perspective section is a diagram that shows the sliced-open picture of things

to-be-built, BUT The interior details are drawn in perspective.
