Knowra Technical drawing Technical drawing Technical drawing is the precise graphical communication of an object's form, dimensions, and construction. It uses standardized views, symbols, and conventions so designs can be interpreted and made accurately.
Orthographic projection : A method of representing a three-dimensional object with separate two-dimensional views projected at right angles. Front, top, and side views communicate shape without perspective distortion.
Technical drawing standards : Formal rules governing the representation, annotation, and interpretation of technical drawings. Standards make conventions consistent across designers, suppliers, and manufacturers.
Architectural drawing : A drawing that represents a building's design, dimensions, materials, and construction details. Building plans and sections apply technical drawing conventions to architectural work.
Descriptive geometry : The mathematical study of representing three-dimensional objects on two-dimensional surfaces using projection methods. Its methods provide the geometric foundation for precise multiview representation.
Isometric projection : A pictorial projection showing three principal axes equally foreshortened, typically at 120-degree angles. It supplies a compact three-dimensional view alongside orthographic views.
Engineering drawing : A technical drawing that defines an engineered component or assembly for design, manufacture, or inspection. It is the principal technical-drawing form used to specify engineered products.
Mechanical drawing : A drawing specifying the shape, dimensions, materials, and manufacturing requirements of mechanical parts or assemblies. It applies the general method to machines and manufactured components.
Gaspard Monge : A French mathematician who systematized descriptive geometry in the late eighteenth century. Monge's work formalized projection methods central to engineering drawing.
Section drawing : A drawing that reveals interior features by depicting an object as cut along an imagined plane. Cutaway views expose internal construction hidden in exterior views.
Computer-aided design : The use of computer software to create, modify, analyze, or optimize designs. CAD systems produce and revise precise technical drawings from digital geometry.
