A 2D geometric model is a geometric model of an
object as two-dimensional figure, usually on the Euclidean or
Cartesian plane.
Even though all material objects are three-dimensional, a 2D geometric model is often adequate for certain flat objects, such
as paper cut-outs and machine parts made of sheet metal.
2D geometric models are also convenient for describing certain types of artificial images, such as technical diagrams, logos, the glyphs of a font, etc. They
are an essential tool of 2D computer graphics and often
used as components of 3D geometric models, e.g. to describe the decals to be applied
to a car model.
