27、dards. It is not the intentof this Standard to be a standalone document for the purpose of addressing basic practices. Anaccurate perception of engineering drawing practices is derived by treating ASME Y14.100,ASME Y14.24, ASME Y14.34, ASME Y14.35, and ASME Y14.41 as a composite set.This Standard is
28、 a revision of ASME Y14.100-2004, Engineering Drawing Practices. The revisionof this Standard was initiated after the official release of ASME Y14.100M-2000. The initial attemptto convert the DoD drawing practices standard, MIL-STD-100, to a nongovernment standardresulted in two drawing practices st
29、andards: ASME Y14.100M-1998, which consisted of basicpractices common to DoD and industry, and MIL-STD-100G, which consisted of those practicesand requirements unique to DoD. The impact on the community was that judgments on whento use which Standard as a standalone or in combination was causing a g
30、ood deal of confusion.Accordingly, the realization of the problems presented by the existence of two basic drawingpractices standards is the basis for the issue of this revision. The consensus was that one standardwas needed. To accomplish this, this Standard contains appendices that may be invoked
31、andtailored by DoD, thereby making possible the cancellation of MIL-STD-100.It is not the intent of this Standard to prevent individual organizations from designing specificdrawing practices that meet their individual needs but rather to provide common engineeringdelineation standards to aid the inc
32、reasing interchange of drawings between industry, government,and other users. It is well recognized that individual companies have many detailed requirementsfor their specific method of operation. Consequently, the minimum requirements set forth in thisStandard will provide them flexibility in imple
33、mentation. The appendices are intended for use byother than strictly commercial applications, such as DoD. However, nothing prevents commercialorganizations from using the appendices and tailoring them as necessary to meet their ownneeds.The successful revision of this Standard is attributed to the
34、subcommittee members and theirrespective companies and the Departments and Agencies of the U.S. government.Suggestions for improvement of this Standard are welcome. They should be sent to TheAmerican Society of Mechanical Engineers; Attention: Secretary, Y14 Main Committee, Two ParkAvenue, New York,

Revisions are made periodically to the Standard to incorporate changesthat appear necessary or desirable, as demonstrated by the experience gained from the applicationof the Standard. Approved revisions will be published periodically.The Committee welcomes proposals for revisio
44、ns to this Standard. Such proposals should beas specific as possible, citing the paragraph number(s), the proposed wording, and a detaileddescription of the reasons for the proposal, including any pertinent documentation.Proposing a Case. Cases may be issued for the purpose of providing alternative
