What is Cross section (geometry)?
[[Image:Seal_mechanical_compression.png|thumb|left|150px|A 2-D cross-sectional view of a compression seal.]] [[Image:Cross section.png|thumb|150px|A 3-D view of a [[beverage-can stove]] with a '''cross section''' in yellow.]] A '''cross section''' is what one gets if one cuts an object into slices. In [[geometry]] the correct definition of ''cross section'' is: the [[intersection]] of a [[Physical body|body]] in 2-dimensional [[Space (physics)|space]] with a [[line]], or of a body in 3-dimensional space with a [[Plane (mathematics)|plane]]. A cross section, or '''section''' is also an [[orthographic projection]] of a 3-dimensional object from the position of a plane through the object. A [[floor plan]] is a section viewed from the top. ==Related pages== * [[Orthographic projection]] * [[Plans (drawings)]] {{Math-stub}} [[Category:Geometry]]
