Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing.This list includes abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies.
ISO 3098-1:1974 Technical Drawing — Lettering — Part I: Currently Used Characters; ISO 4172:1991 Technical drawings — Construction drawings — Drawings for the assembly of prefabricated structures; ISO 5261:1995 Technical drawings — Simplified representation of bars and profile sections; ISO 5455:1979 Technical drawings — Scales
Various scales may be used for different drawings in a set. For example, a floor plan may be drawn at 1:50 (1:48 or 1 ⁄ 4 ″ = 1′ 0″) whereas a detailed view may be drawn at 1:25 (1:24 or 1 ⁄ 2 ″ = 1′ 0″). Site plans are often drawn at 1:200 or 1:100. Scale is a nuanced subject in the use of engineering drawings.
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
The structural drawings set has different subsets: General Notes, Plans, Elevations, Sections, and Details General Notes are part of structural drawings and they cover the codes used in design and the by-laws of the building. Typically there are no details on these drawings. Structural notes provide information regarding general material ...
ASME Y14.41-2012 is based upon ASME Y14.5-2009 symbols and definition methods, such as Geometry Dimensioning and Tolerancing (GD&T). Subscribers of International Organization for Standardization (ISO) have the standards ISO 1101 and ISO 16792 for model-based definition.
Working drawings are the set of technical drawings used during the manufacturing phase of a product. [15] In architecture, these include civil drawings, architectural drawings, structural drawings, mechanical systems drawings, electrical drawings, and plumbing drawings.
Mechanical structures, such as aircraft, satellites, rockets, space stations, ships, and submarines, have their own particular structural loads and actions. [33] Engineers often evaluate structural loads based upon published regulations, contracts, or specifications. Accepted technical standards are used for acceptance testing and inspection.
