What cross sections and profiles are there in architectural drawing? I don't understand. Who can tell me?

A cross-section is a cross-sectional shape obtained by cutting in a direction perpendicular to an object with respect to a longitudinal cross-section. Generally speaking, for slender objects or three-dimensional shapes, the cross section obtained by cutting in a shorter direction (or a longer vertical direction) is the cross section. In ship engineering, the cross section is usually used as the intermediate cross section.

Longitudinal section refers to the surface of an object after cutting along its axis. ?
