This Standard establishes requirements and refer- ences documents applicable to the preparation and revi- sion of digital product definition data, hereafter referred to as data sets. This Standard defines exceptions and additional requirements to existing ASME standards for using product definition digital data sets or drawings in digital format. Where no exception or additional f quirements are stated, existing ASME standards shall apply.
1.2 Structure of Standard This Standard supports two methods of application: model only, and model and drawing in digital format. The structure starts with the requirements common to both methods, and then branches to the other sections that have differing requirements for each method. In addition, it provides a guide for the many CAD software packages to develop better modeling and annotation practices for computer aided design and engineering disciplines.
1.3 Figures The figures in this Standard are intended only as ilus- trations to aid the user in understanding the practices described in the text. In some cases, figures show a level of detail as needed for emphasis; in other cases, figures are only complete enough to ilustrate a concept or facet thereof. The absence of figures has no bearing on the applicability of the specifed requirement or practice. To comply with the requirements of this Standard, actual data sets shall meet the content requirements set forth in the text. To assist the users of this Standard, a listing of the paragraph(s) that refer to an ilustration appears in the liower right-hand cormer of each figure. This listing may not be all-inclusive. The absence of the listing is not a reason to assume inapplicability. Most figures are ilustrations of models in a three- dimensional environment. Figures llustrating drawings in digital format have a border included. 1.4 Reference to This Standard When data sets are based on this Standard, this fact shall be noted in the data set or in a document referenced by the data set. References to this Standard shall state ASME Y14.41-2003.
1.5 Units The International System of Units (SD) is featured in this Standard. United States (U.S.) customary units could equally well have been used without prejudice to the principles established.
1.6 Text In Figures Text in upper case letters used in the figures is in- tended to appear in data sets. Text in lower case letters is explanatory of the figures only and is not intended to appear in data sets.
1.7 Symbols The use of symbols to indicate dimensional require- ments does not preclude the use of equivalent terms or abbreviations in accordance with ASME Y14.38 where symbology is considered inappropriate. 1.8 References ASME Y14.1-1995 (R2002), Decimal Inch Drawing Sheet Size and Format ASME Y14.1M-1995 (R2002), Metric Drawing Sheet Size and Format ASME Y14.2M-1992 (R1998), Line Conventions and Let- tering ASME Y14.3M-1994 (R1999), Mutiview and Sectional View Drawings ASME Y14.4M-1989 (R1999), Pictorial Drawing ASME Y14.5M-1994 (R1999), Dimensioning and Toler- ancing ASME Y14.8M-1996 (R2002), Castings and Forgings ASME Y14.35M-1997, Revision of Engineering Drawings and Associated Documents ASME Y14.38-1999, Abbreviations and Acronyms ASME Y14.100 2000, Engineering Drawing Practices Publisher: The American Society of Mechanical Engi- neers (ASME International), Three Park Avenue, New York, NY 10016-5990; Order Department: 22 Law Drive, Box 2300, Fairfield, N] 07007-2300 IEEE/ ASTM SI 10, Standard for Use of the International System of Units (S): The Modern Metric System Publisher: Institute of Electrical and Electronics Engi- neers (IEEE), 445 Hoes Lane, Piscataway, NJ 08854- 1331.ASME Y14-41 pdf download.
