Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 [1] is one of the standards. Australia utilises the Technical Drawing standards AS1100.101 (General Principals), AS1100-201 (Mechanical Engineering Drawing) and AS1100-301 (Structural ...
Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering .
In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard S5.1; The primary schematic drawing used for laying out a process control installation. They usually contain the following information:
The standard AIA (American Institute of Architects) and EJCDC (Engineering Joint Contract Documents Committee) states that the drawings and specifications are complementary, together providing the information required for a complete facility.
The standard is divided into three parts: ISO 13567-1:2017 [1] Technical product documentation — Organization and naming of layers for CAD — Part 1: Overview and principles
