what is technical drawing

Technical drawing, also known as drafting, 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. Technical drawings are made at a precise scale and include elements that make them unambiguous, meaning that their elements can be interpreted only in one way. Technical drawings use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout to make the drawings easier to understand. Together, such conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Technical drawing is different from artistic drawing because it aims for precision, while artistic drawings aim to provide aesthetical pleasure. Technical drawing is used in mechanical drawing to create detailed drawings of parts and assemblies, including exploded views, section views, and diagrams. Technical drawing is an important component of architecture, engineering, and construction. Some of the most common applications that require technical drawing skills include mechanical drawing, assembly drawing, working drawings, architectural drawings, and detail drawings.
