1.2.5 Notes. Notes depicted in this Standard in ALL UPPERCASE letters are intended to reflect actual product definition data. Notes depicted in initial uppercase or in lowercase letters are to be considered supporting data to the contents of this Standard and are not intended for literal entry into product definition data. A statement requiring the addition of a note with the qualifier “such as” is a requirement to add a note, and the content of the note is allowed to vary to suit the application. 1.2.6 Acronyms and Abbreviations. Acronyms and abbreviations are spelled out the first time they are used in this Standard, followed by the acronym or abbreviation in parentheses. The acronym is used thereafter throughout the text. 1.2.7 Units. The International System of Units (SI) is featured in this Standard. It should be understood that U.S. Customary units could equally have been used without prejudice to the principles established. 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 show a level of detail as needed for emphasis. In other cases, 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 of the stated requirements 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 user of this Standard, a list of the paragraph(s) that refer to an illustration appears in the lower right-hand corner of each figure. This list may not be inclusive. The absence of a list is not a reason to assume inapplicability. Some figures are illustrations of models in a three-dimensional (3D) en- vironment. The absence of dimensioning and tolerancing annotations in a view may indicate that the product definition is defined in three dimensions.
coordinate system (ASME Y14.41): a representation of a Cartesian coordinate system in a product definition data set. datum (ASME Y14.5): a theoretically exact point, axis, line, plane, or combination thereof derived from the theoretical datum feature simulator. datum feature (ASME Y14.5): a feature that is identified with either a datum feature symbol or a datum target symbol. end product (end item) (ASME Y14.24): an item, such as an individual part or assembly, in its final or completed state. free zone: a type of bounded volume region that encloses the entire part and in which other parts cannot be located or intersected. gradient control: specifies, with tolerance, how physical characteristics are varied spatially (e.g., changes in material composition, color, density, porosity, or unit cell size). lattice structures (ISO/ASTM 52900 1 ): three dimensional geometric arrangement composed of connective links between vertices (points) creating a functional structure. nesting (ISO/ASTM 52900 1 ): situation when parts are made in one build cycle and are located such that their bounding boxes, arbitrarily oriented or otherwise, will overlap. part (ASME Y14.100): one item, or two or more items joined together, that is not normally subject to disassembly without destruction or impairment of designed use, e.g., transistor, composition resistor, screw, transformer, and gear. product data package type: a specific product definition data set that defines a particular stage of manufacturing and conformance to specification. product definition data (ASME Y14.41): denotes the totality of data elements required to completely define a product. Product definition data includes geometry, topology, relationships, tolerances, attributes, and features necessary to completely define a component part or an assembly of parts for the purpose of design, analysis, manufacture, test, and inspection. product definition data set (ASME Y14.41)
