Section
Section is an imaginary or real cut through a solid by a plane. Two kinds of sections are: longitudinal section and cross-section or transverse section.

A section line is a line drawn in a plane round a form - the perimeter or part of the perimeter of a true section. Often used by sculptors to give a clear idea of the form of the sculpture on a two-dimensional surface. Also used in life-modelling classes on the model's body, to stimulate appreciation of the changes of section in a limb or torso.
