Nevertheless, it is advisable to consult the separate standards referenced in Clause 2Īnd in Table 2 for more Mechanical engineering drawings ISO 1101 represents the initial basis and describes the required fundamentals for ISO 128 is an international standard (ISO), about the general principles of presentation in technical drawings, specifically the graphical representation of objects on technical drawings. The standards follow the development in engineering. Standardization is a dynamic and continuous process. Standardization also aids with internationalization, because people from different countries who speak different languages can share the common language of engineering drawing, and can thus communicate with each other quite well, at least as concerns the geometry of an object.

Following the goal of unambiguous communication, engineering drawings are often made professionally and expected to follow certain national and international standards, such as ISO standards.
