| ASME Y14.41 - Digital Product Definition Data Practices | Reference | 2019 | 
| A combination of model, annotation, and attributes that describe a product. | 
| Visible dimensions, tolerances, notes, text, or symbols. | ![]()  | 
| A conceptual plane containing annotation that either perpendicularly intersects, or is coincident with one or more surfaces of a feature. | 
| A model in which the product described is an assembly of two or more items. | ![]()  | 
| The portion of a product definition to which annotation pertains. | 
| A user-defined set of related digital elements. | 
| The established relationship between digital elements. | 
| A dimension, tolerance, note, text, or symbol required to complete the product definition or feature of the product that is not visible but available upon interrogation of the model. | ![]()  | 
| 
 A designation assigned to product definition data that defines what product definition elements are included within the drawing graphic sheet, data set, or both.
 NOTE: A drawing graphic sheet may be in either physical or electronic format.  | 
| 
 Drawing Graphic Sheet With Optional Data Set
 Identifies that product definition elements are located on the drawing graphic sheet.  | 
| 
 Data Set With Model and Drawing Graphics Sheet
 Identifies that product definition elements are located on a drawing graphic sheet. A computer is used as a tool to prepare the drawing graphics sheet and model. Product definition elements are located in the digital data and drawing graphic sheet. 
  | 
| 
 Data Set With Model and Simplified Drawing Graphics Sheet
 Identifies a model with a simplified drawing graphic sheet used to expedite communication of common part features and to define nongeometric part definitions.  | 
| 
 Data Set With Annotated Model and Drawing Graphics Sheet
 Identifies that all product definition elements are located in both the digital data and drawing graphic sheet.  | 
| 
 Data Set With Annotated Model and No Drawing Graphic Sheet
 Identifies that all product definition elements are located in the data set. No drawing graphic sheet exists. 
  | 
| A representation of a Cartesian coordinate system in a product definition data set. | ![]()  | 
| Information represented in a formal manner suitable for communication, interpretation, or processing by human beings or computers. | 
| Data duplicated or extracted from the original. A copy of a derivative is also a derivative. | 
| The portion of the data set that contains model geometry and supplemental geometry. | 
| Geometric element, feature, group of features, annotation, associated group, or attribute that exists in a data set. | 
| A label or name used to specify a unique digital element. | 
| A graphic entity used in a data set. For example: point, line, plane, surface, solid, coordinate system, or crosshatching. | 
| A model in which the product described is an installation, showing parts or assemblies and a partial or complete representation of the installation site. | 
| The data required for the release, control, and storage of product definition data as well as other relevant engineering data. | 
| The portion of the data set that contains model geometry and supplemental geometry. | ![]()  | 
| Geometric elements in product definition data that represent an item. | 
| The numerical value derived by interrogating the model that quantifies the form and spatial relationships of the geometry composing a design model, or assembly of models, to the precision (number of decimal places) of the computer system. | 
| 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. | 
| A collection of one or more data file(s) that discloses, directly or by reference, by means of presentation (e.g., graphic or textual), representation (e.g., semantics or machine readable), or a combination of both, the physical or functional requirements of an item. | 
| A means of interrogating a digital element or the relationship between digital elements. | 
| A supplemental geometry line or curve segment indicating the orientation of a direction dependent tolerance. | 
| A model value that is rounded off to the number of decimal places required for the design. | ![]()  | 
| A drawing with minimal views and dimensional characteristics that relies on the model to provide complete part definition. | 
| Geometric elements included in product definition data to communicate design requirements but not intended to represent a portion of an item. | ![]()  |
