 |
| Model Based Enterprise |
MBE |
Fully integrated and collaborative environment founded on 3D product definition detailed and shared across the enterprise to enable rapid, seamless, and affordable deployment of products from concept to disposal.

| Model Based Engineering |
MBE |
DEFINITION IN WORK |
 |
| Engineering Drawing |
Drawing |
Two-dimensional (2D) flat orthogonal representations of a 3 dimensional object; used to convey design, manufacturing and quality support information related to how an object is to be built, such as dimensions, tolerances, materials, construction notes and processes. Standardized by ASME Y14.5 and Y14.100. |
 |
| Model |
CAD, Data Set |
A digital, mathematically correct three-dimensional (3D) representation of an object generated with nominal precise geometry. |
 |
| Analysis Model |
FEM |
A CAD model that contains additional product definition information required to perform product analysis (static, dynamic, thermal, etc. ). Most likely contains mesh elements to make it a Finite Element Model (FEM) and may contain control software to predict the product's behavior. This may or may not be a derivative of the parent 3D CAD Model. |
 |
| Physical Model |
|
DEFINITION IN WORK |
 |
| Surface Model |
|
Mathematical or digital representation of an object as a set of planar or curved surfaces, or both, that may or may not represent a closed volume. |
 |
| CAD |
Model |
A digital file(s) produced from any CAD software package. Many file formats are possible. |
 |
| 3D CAD |
Model |
The digital file(s) produced from any CAD software package that is the 3D model of an object. It may or may not include Product and Manufacturing Information (PMI) annotations. |
 |
| 2D CAD |
Drawing File |
The digital file produced from any CAD software package that creates a 2D engineering drawing which is the source for either printed paper or a digital 2D formatted file. These files may or may not derive from their 3D CAD parent.
|
 |
| Graphic |
Drawing |
Pictorial representation of a 3D model or 2D drawing. Generally it is captured as a screen shot. The image can be isometric or planar, cartoon-like, 3D, realistic or line art.
|
 |
| Record of Authority |
Master |
Identifies what document serves as the primary and governing source for product documentation. Other documentation can be derived from this source and additional documentation may be added to support the manufacture of the product. |
 |
| Derivative |
Translated Models, Drawing |
Data duplicated or extracted from the original. A copy of a derivative is also a derivative.
|
 |
| Annotation |
Note, Dimension |
Dimensions, tolerances, notes, text, or symbols visible without any manual or external manipulation.
|
 |
| Product Manufacturing Information |
PMI |
Annotations and meta-data captured within the the 3D CAD model that are non-geometric attributes necessary to convey information for the manufacture of the product.
|
 |
| Fully Annotated Model |
Master Model |
A 3D CAD model that includes all PMI and is the record of authority for all the product's geometry, materials, GD&T, BOM and notes. |
 |
| Model Based Definition |
MBD, Model Only |
A 3D annotated model and its associated data elements that fully define the product definition in a manner that can be used effectively by all downstream customers in place of a traditional drawing.
|
 |
| Model Based Design |
MBD, Model-Centric Design |
A development approach which declares the 3D CAD model as the record of authority and is the source for which all other documentation flows. This design method facilitates MBE, by emphasizing digital CAD file use for collaboration at the beginning of development.
|
 |
| Technical Data Package |
TDP, Product Definition Data Set |
The complete digital data set that is required to manufacture a product and requires configuration management.
|
 |
| Product |
Thing |
An item to be created and used in the world. It can be a single part or an assembly of parts. |
 |
| Product Definition Information |
PDI |
Information that defines the product's requirements, documents the product's attributes and is the authoritative source for configuration definition and control. |
 |
| Product Data Management |
PDM |
The tracking, control and status control of product data, either as files, or through a database. The usage is frequently confined to the design stage of product development, although may extend to planning for manufacture. |
 |
| Product Lifecycle Management |
PLM |
The tracking, control and status control of product data, either as files, or through a database. PLM extends the scope of PDM to include each physical product produced from a design, including deviations from the design and usage of the product. |
 |
| Additive Manufacturing |
AM, Direct Digital Manufacturing (DDM), Rapid Prototyping (RP), Digital Printing, Freeform Fabrication |
Process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies.
