摘要：The main tools of CAD: the 2D Drawing/Drafting or 3D Parametric Feature Based Solid/Surface Modelling are used for product development. CAD systems increase the quality of drawings and reduce the time for its preparation. In this process, it is very important to use the valid standards for the drawings and technical documentation. Standardization documents describing the rules, regulations and requirements of production methods, concepts, symbols, constructor’s drawings and other documents are very important in all areas of industry.
