What is a detailed drawing engineering?

A detail drawing is a tool used by engineers to communicate their designs to manufacturers and to preserve their work for future generations. To facilitate the sharing of design information, engineers have created uniform standards, protocols and tools. One of these standards is called the ANSI Y14.

How many parts are there in ISO 128?

fifteen parts
Since 2003 the ISO 128 standard contains fifteen parts, which were initiated between 1996 and 2003. It starts with a summary of the general rules for the execution and structure of technical drawings.
