Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering .
In isometric projection, the most commonly used form of axonometric projection in engineering drawing, [4] the direction of viewing is such that the three axes of space appear equally foreshortened, and there is a common angle of 120° between them. As the distortion caused by foreshortening is uniform, the proportionality between lengths is ...
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component.
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.
In technical drawing and computer graphics, a multiview projection is a technique of illustration by which a standardized series of orthographic two-dimensional pictures are constructed to represent the form of a three-dimensional object.
Conversely, psychology defines bottom–up processing as an approach in which there is a progression from the individual elements to the whole. According to Ramskov, one proponent of bottom–up approach, Gibson, claims that it is a process that includes visual perception that needs information available from proximal stimulus produced by the ...
Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing. This list includes abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies.
Graphic Communications focuses on the technical aspects of producing and distributing items of visual communication. This includes technical aspects associated with the production of tangible items such as books, magazines and packaging, as well as digital items such as e-newsletters, interactive apps, websites, video and virtual reality applications.
