Today, the mechanics of the drafting task have largely been automated and accelerated through the use of computer-aided design systems (CAD). There are two types of computer-aided design systems used for the production of technical drawings: two dimensions (2D) and three dimensions (3D). An example of a drawing drafted in AutoCAD
The drawing board is usually mounted to a floor pedestal in which the board turns to a different position, and also its height can be adjustable. Smaller drawing boards are produced for table-top use. In the 18th and 19th centuries, drawing paper was dampened and then its edges glued to the drawing board.
The terms computer-aided drafting (CAD) and computer-aided design and drafting (CADD) are also used. [2] Its use in designing electronic systems is known as electronic design automation (EDA). In mechanical design it is known as mechanical design automation (MDA), which includes the process of creating a technical drawing with the use of ...
It consists of a length of tube of around 4 mm to 6 mm in diameter, often made of coiled steel springs, with a push-button on one end.Three metal wires protrude from the other end, each sprung to bend outwards, away from the tube's axis, but with their tips bent inwards to form teeth.
Example mechanical drawing. Here is an example of an engineering drawing (an isometric view of the same object is shown above). The different line types are colored for clarity. Black = object line and hatching; Red = hidden line; Blue = center line of piece or opening; Magenta = phantom line or cutting plane line
Technical illustration and computer-aided design can also use 3D and solid-body projections, such as rapid prototyping. In the natural sciences, "scientific illustration" refers to a style of drawing using stippling and simple line techniques to convey information with a minimum of artistic interpretation.
Traditional drafter at work A drafter in Portugal in the 1970s, using a drafting machine. A drafter (also draughtsman / draughtswoman in British and Commonwealth English, draftsman / draftswoman, drafting technician, or CAD technician in American and Canadian English) is an engineering technician who makes detailed technical drawings or CAD designs for machinery, buildings, electronics ...
Visual design tools are, for example, gesture, sketch, drawing, scale model, perspective drawing, photograph, film, video. Eugene S. Ferguson's 1977 paper in Science, entitled "The mind's eye: Nonverbal thought in technology", is credited for clarifying the role of visual reasoning in the thinking process. [6]
