A 2D CAD drawing A 3D CAD model Computer-aided design ( CAD ) is the use of computers (or workstations ) to aid in the creation, modification, analysis, or optimization of a design . [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to ...
A man using AutoCAD 2.6 to digitize a drawing of a school building. AutoCAD was derived from a program that began in 1977, and then released in 1979 [5] called Interact CAD, [6] [7] [8] also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle.
An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building ...
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]
Blind contour drawing is a drawing exercise, where an artist draws the contour of a subject without looking at the paper. The artistic technique was introduced by Kimon Nicolaïdes in The Natural Way to Draw , and it is further popularized by Betty Edwards as "pure contour drawing" in The New Drawing on the Right Side of the Brain .
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

Artists may choose to "correct" perspective distortions, for example by drawing all spheres as perfect circles, or by drawing figures as if centered on the direction of view. In practice, unless the viewer observes the image from an extreme angle, like standing far to the side of a painting, the perspective normally looks more or less correct.
