FOREWOR

The development of this Standard was initiated at the request of industry and the government. A meeting was held to determine the interest in this subject subject in January 199 1997 7 in Wichita Kansas hosted by The Boeing Company in their facility. facility . A subsequent meeting was held during the spring ASME meeting in 1997 to enlist membership of those who would be interested in working this project. This Standard was largely built using the e-mail systems now available to industry and govern ment. This was actually a revolutionary happening since in some part the subcommittee was establishing ground rules for the use of 3 0 data in new design systems that were not fully tested or fully developed . The subcommittee understands a need for documented systems and systematic work. The evolution of the tools available to those that create and produce drawings has enhanced the capabilities of designers in producing complex hardware . The computer and the computer graphics design software is at a stage where using the design package to extend the normal drawing usage to a new level is a real possibility. possibility . Those who have chosen to spend the time and effort in the definition of the product shall see a return on their investments associated with implementing three-dimensional drawing packages. The accuracy of the product design is unpar alleled and provides the users of the design data the ability to interrogate the digital data t hat Companies were on how to use these innovative controls the There design. techniques. were many issues inclamoring 3 0 guidelines and inspection of using the for data for the manufacture the product. This is indeed a first first since digital data was usable in the manufacturing of the product but was widely disapproved for inspection. The intent of this Standard is to set forth a logical and manageable system in the use of the new design systems available to manufacturers both large and small. This advancement is a change in media used in the design manufacture and inspection cycles of the product. Suggestions for improvement of this Standard are welcomed . They should be sent to The American Society of Mechanical Engineers Attention: Secretary Y14 Main Committee Three Park Avenue New York NY 10016. This Standard was approved as an American National Standard on July 7 2003.

1 1 Scope 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 exist ing ASME standards for using product definition digital data sets or drawings in digital format. Where no exception or additional re quirements are stated, existing ASME standards shall apply.

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

1 2 Structure of Standard This Standard supports two methods of application: application :

The use of symbols to indicate dimensional require

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.

ments does not preclude the use of equivalent terms or abbreviations in accordance with ASME Y14.38 where symbology is considered inappropriate.

The figures in this Standard are intended only as illus 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 illustrate a concept or facet thereof. The absence of figures has no bearing on the applicability of the specified 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 illustration appears in the lower right-h and corner 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 illustrations of models in a three dimensional environment. Figures illustrating drawings in digital format have a border included.

model completeness shall be in accordance with para. 4.1.2, except part and sub-assembly models shown in

the assembly model need only have sufficient detail

shown to ensure correct identification, orientation, and placement. The assembly model may be shown in an

exploded, partially assembled, or completely assembled state.. The placement of parts and sub-assemblies within state the assembly may alternatively be defined via annotation, or a combination of annotation and pictorial repre sentation of the model. 4.1.4 Installation Model Completeness. Installation

completeness shall be in accordance with paras. 4.1.2 and 4.1.3, except part and assembly models shown in the installation model need only be sufficiently detailed to provide installation and space req uirements.

The following paragraphs describe requirements for annotation applied to a design model. These are general requirements that apply to all types of annotation. Spe cific requirements for particular types of annotation are addressed in Sections 6 through 10 See Fig. 5-2 for a diagram showing the relationship between annotation and model geometry . 5.2.1 Associativity.

The following are general re

quirements for defining an associative relation relationship ship be tween digital elements.

a) Selection of Associated Associated Entities Annotation may be associated to a feature, a group of features, or a portion of an applicable feature. For an example of the associated featur es for a dime nsio n, see Fig Fig.. 5-3 5-3.. b) Associa ted Groups. Annotation, model geometry, and supplemental geometry may be placed into associ ated groups to indicate their relationships. For example: 1) Supplemental geometry used to define location, orientation, or further clarify the application of annota tion to a model. 2) A model coordinate system for datum symbols and datum targets . 3) Other Annotation This could include qualifying notes and size limit callouts.

5.2.2 Attributes. Attributes are used to capture addi tional information that is not shown using geometry or in the model annotation . Attributes shall be available on demand. Attributes may be presented using text de scription, forms, or other techniques. See Fig. 5-4 for an example of how the attributes of a hole could be represented. Applications of attributes include, but are not limited to, coatings, knurling, threaded hol es, and pins .
