What is descriptive geometry all about

Descriptive geometry A branch of geometry in which three-dimensional figures, as well as methods for solving and investigating three-dimensional problems, are studied by representing them in the plane.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. The theoretical basis for descriptive geometry is provided by planar geometric projections.Descriptive geometry is a branch of mathematics used to transform three-dimensional objects into two-dimensional representations that can then be presented on paper, computer screens, or some similar medium. Its principles are valuable for determining true shapes of planes, angles between lines, and locating intersection between line and planes.

The branch of geometry that investigates projections, including a study of the properties that are preserved under them, goes under the name of projective geometry. Descriptive geometry is really a subfield of projective geometry. Problems solved using descriptive geometry can be intricate.
