This Standard establishes the requirements for creat- ing orthographic, and pictorial views on engineering drawing graphic sheets and in models. View require- ments are generally the same regardless of how they are created. Specific requirements that are applicable only to constructed or to saved views are defined throughout the standard. The topics covered include the multiview system of drawing, selection, and arrangement of orthographic views, auxiliary views, section views, details, pictorial views, conventional representation of features with some practices applicable only to constructed views, practices applicable to saved views on drawing graphic sheets, and practices applicable only to saved views in models. The methods for constructing orthographic and pic- torial views are beyond the scope of this Standard. Space geometry and space analysis and applications are included in the appendices for informational purposes. 1.2 ASME Y14 Series Conventions The following conventions in paras. 1.2.1 through 1.2.10 are used in this and other ASME Y14 series of standards. 1.2.1 Mandatory, Nonmandatory, Guidance, and Optional Words (a) The words “shall” and “will” establish a manda- tory requirement. (b) The words “should” and “may” establish a rec- ommended practice. (c) The words “typical,” “example,””for reference,” or the Latin abbreviation “e.g.” indicate suggestions given for guidance only. (d) The word“or” used in conjunction with a manda- tory requirement or a recommended practice indicates that there are two or more options for complying with the stated requirement or practice. 1.2.2 Cross-Reference of Standards. Cross-reference of standards in text with or without a date following the standard identity shall be interpreted as follows:(a) Reference to other ASME Y14 series of standards in the text without a date following the standard identity indicates that the issue of the standard as identified in the references section shall be used to meet the requirement. (b) Reference to other ASME Y14 series of standards in the text with a date following the standard identity indicates that only that issue of the standard shall be used to meet the requirement. 1.2.3 Invocation of Referenced Standards. The fol- lowing examples define the invocation of a standard when specified in the references section and referenced in the text of this Standard: (a) When a referenced standard is cited in the text with no limitations to a specific subject or paragraphs(s) of the standard, the entire standard is invoked. For example, “dimensioning and tolerancing shall be in accordance with ASME Y14.5” is invoking the com- plete standard because the subject of the standard is dimensioning and tolerancing and no specific subject or paragraph(s) within the standard are invoked. (b) When a referenced standard is cited in the text with limitations to a specific subject or paragraph(s) of the standard, only the paragraph(s) on that subject is invoked. For example, “assign part or identifying num- bers in accordance with ASME Y14.100” is only invok- ing the paragraph(s) on Part or Identifying Numbers because the subject of the standard is engineering draw- ing practices and part and identifying numbers is a spe- cific subject within the standard. (c) When a referenced standard is cited in the text without an invoking statement, such as “in accordance with,” the standard is for guidance only. For example, “for gaging principles see ASME Y14.43”is only for guidance, and no portion of the standard is invoked. 1.2.4 Parentheses Following a Definition. When a definition is followed by a standard referenced in paren- theses, the standard referenced in parentheses is the source for the definition.ASME Y14.3 pdf download.
