1.2.8 Figures. The figures in this Standard are intended only as illustrations to aid the user in understanding the practices described in the text. In some cases, figures showa level ofdetail as needed foremphasis. In othercases, figures are incomplete by intent so as to illustrate a concept or facet thereof. The absence of figure(s) has no bearing on the applicability ofthe stated requirements or practice. To comply with the requirements ofthis Standard, actual data sets shall meetthe contentrequirements setforth in the text. To assistthe userofthis Standard, a listofthe paragraph(s) that refertoanillustrationappearsinthelowerright-handcornerofeachfigure.This listmaynotbeall-inclusive.Theabsence of a list is not a reason to assume inapplicability. A lowercase “h” is used in figures for letter height or for symbol proportions (see Figure 1-1). Select the applicable letter height in accordance with ASME Y14.2. 1.2.9 PrecedenceofStandards. The followingare ASME Y14 standards thatare basicengineeringdrawingstandards: ASME Y14.1, Decimal Inch Drawing Sheet Size and Format ASME Y14.1M, Metric Drawing Sheet Size and Format ASME Y14.2, Line Conventions and Lettering ASME Y14.3, Orthographic and Pictorial Views ASME Y14.5, Dimensioning and Tolerancing ASME Y14.24, Types and Applications of Engineering Drawings ASME Y14.34, Associated Lists ASME Y14.35, Revision of Engineering Drawings and Associated Documents ASME Y14.36, Surface Texture Symbols ASME Y14.38, Abbreviations and Acronyms for Use on Drawings and Related Documents ASME Y14.41, Digital Product Definition Data Practices ASME Y14.100, Engineering Drawing Practices All other ASME Y14 standards are considered specialty types of standards and contain additional requirements or make exceptions to the basic standards as required to support a process or type of drawing. 1.2.10 UnlessOtherwiseSpecified.Thephrase“unlessotherwisespecified”(UOS) isusedtoindicateadefaultrequire- ment. The phrase is used when the default is a generally applied requirement and an exception may be provided by another document or requirement. 1.3 Reference to This Standard When drawings ordata sets are based on this Standard, this factshall be noted on the drawingorin the data set. Anote similar to the following shall be added: “THIS DRAWING SHALL BE INTERPRETED IN ACCORDANCE WITH ASME Y14.100-2017 EXCEPT AS AMENDED BY ASME AED-1–2018.” When this Standard in its entirety is notrequired, specific tailoring may be accomplished in a company interpretation document, drawing note, etc. 2 REFERENCES The following revisions ofAmerican National Standards form a part ofthis Standard to the extent specified herein.
