Descriptive geometry is the branch of geometry which allows the representation of three-dimensional objects in two dimensions by using a specific set of procedures. The resulting techniques are important for engineering, architecture, design and in art. [1] The theoretical basis for descriptive geometry is provided by planar geometric projections.
Stereotomy is strongly associated with stonecutting and has a very long history. Descriptive geometry can be considered as an evolution of streotomy. [3] In technical drawing stereotomy is sometimes referred to as descriptive geometry, and "is concerned with two-dimensional representations of three dimensional objects. Plane projections and ...
Gaspard Monge, Comte de Péluse (French pronunciation: [ɡaspaʁ mɔ̃ʒ kɔ̃t də pelyz]; 9 May 1746 [2] – 28 July 1818) [3] was a French mathematician, commonly presented as the inventor of descriptive geometry, [4] [5] (the mathematical basis of) technical drawing, and the father of differential geometry.

1870 – Felix Klein constructs an analytic geometry for Lobachevski's geometry thereby establishing its self-consistency and the logical independence of Euclid's fifth postulate, 1873 – Charles Hermite proves that e is transcendental, 1878 – Charles Hermite solves the general quintic equation by means of elliptic and modular functions
The Rytz’s axis construction is a basic method of descriptive geometry to find the axes, the semi-major axis and semi-minor axis and the vertices of an ellipse, starting from two conjugated half-diameters. If the center and the semi axis of an ellipse are determined the ellipse can be drawn using an ellipsograph or by hand (see ellipse).
