Drawing title (hence the name "title block") Drawing number; Part number(s) Name of the design activity (corporation, government agency, etc.) Identifying code of the design activity (such as a CAGE code) Address of the design activity (such as city, state/province, country) Measurement units of the drawing (for example, inches, millimeters)
A fabrication is made up of many different parts. A fabrication drawing has a list of parts that make up the fabrication. In the list, parts are identified (balloons and leader lines) and complex details are included: welding details, material standards, codes, and tolerances, and details about heat/stress treatments. and also [2]
Typical fields in the title block include the drawing title (usually the part name); drawing number (usually the part number); names and/or ID numbers relating to who designed and/or manufactures the part (which involves some complication because design and manufacturing entities for a given part number often change over the years due to ...
Process control instrumentation and designation (names, numbers, unique tag identifiers), including: Valves and their types and identifications (e.g. isolation, shutoff, relief and safety valves, valve interlocks) Control inputs and outputs (sensors and final elements, interlocks)
Assembly drawings show how different parts go together, identify those parts by number, and have a parts list, often referred to as a bill of materials. [16] In a technical service manual, this type of drawing may be referred to as an exploded view drawing or diagram. These parts may be used in engineering.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
ISO 128 itself was first published in 1982, contained 15 pages and "specified the general principles of presentation to be applied to technical drawings following the orthographic projection methods". [2] [3] Several parts of this standard have been updated individually. The last parts and the standard as a whole were withdrawn by the ISO in 2001.
A functional block diagram, in systems engineering and software engineering, is a block diagram that describes the functions and interrelationships of a system. The functional block diagram can picture: [1] functions of a system pictured by blocks; input and output elements of a block pictured with lines; the relationships between the functions ...
