Engineering drawing


An engineering drawing is the type of technical drawing that is used toinformation approximately an object. the common ownership is to specify the geometry necessary for the construction of a component and is called a module drawing. Usually, a number of drawings are necessary to completely specify even a simple component. The drawings are linked together by a master drawing or assembly drawing which lets the drawing numbers of the subsequent detailed components, quantities required, construction materials & possibly 3D images that can be used to locate individual items. Although mostly consisting of pictographic representations, abbreviations as well as symbols are used for brevity and additional textual explanations may also be portrayed tothe necessary information.

The process of producing engineering drawings is often described to as technical drawing or drafting draughting. Drawings typically contain multiple views of a component, although additional scratch views may be added of details for further explanation. Only the information that is a requirement is typically specified. Key information such(a) as dimensions is usually only talked in one place on a drawing, avoiding redundancy and the possibility of inconsistency. Suitable tolerances are given for critical dimensions to permit the part to be manufactured and function. More detailed production drawings may be offered based on the information assumption in an engineering drawing. Drawings defecate an information box or title block containing who drew the drawing, who approved it, units of dimensions, meaning of views, the title of the drawing and the drawing number.
