Engineering drawings are usually created in accordance with standardized conventions for layout, nomenclature, interpretatition, appearance, line styles, size, etc. The purpose of drawing is to accurately and unambiguously capture all the geometric features of a product or a component. The end goal of an engineering drawing is to convey all the required information that will allow a manufacturer to produce that component. All engineering drawing uses standard symbols while drawing. The list of symbols is shown in the Table 1. Different line styles are used to convey information such as hidden line, center line, dimension line etc. Standard symbols must be used, while drawing the maps and flow charts.
