Since various companies in industries including aerospace, automotive, agricultural, and heavy equipment had already begun utilizing the CAD data for industrial purposes without a standard, several definitions needed to be established as the universal interpretation. In response to requests from various segments of the industry, a new subcommittee began development of the standard in 1998. For example, ergonomic and aerodynamic contoured surfaces were extremely difficult to define on engineering drawings. In the late 1980s and early 1990s, solid modeling and CAD were becoming important tools for engineers looking to create and define increasingly complex geometry. 2.2 Model and Drawing Graphic Sheet MethodĪSME Y14.41 was born of the need to utilize Computer-aided design (CAD) data as a manufacturing and/or inspection source.The latest revision of ASME Y14.41 was issued on as ASME Y14.41-2019. It was immediately adopted by several industrial organizations, as well as the Department of Defense (DOD). ASME issued the first version of this industrial standard on as ASME Y14.41-2003. Of digital product definition data (also known as model-based definition), which pertains to CAD software and those who use CAD software to create the product definition within the 3D model.
