Technical Drawing

 

(in Russian, chertezh), a scale projection of objects presented on some information carrier, such as standard or tracing paper, film, or a type of veneer, by means of graphic forms—points, segments of straight and curved lines, symbols, standard designations, and the like. Technical drawings may be used as illustrations to a text (to explain material to be learned) or as documentation for the manufacture of goods. They may be accompanied by explanatory notes, specifications, and instructions for manufacture of the article (when necessary) and may take the form of mechanical drawings, sketches, or diagrams.
