Term
 Annotate
Definition
 To add explanatory notes to a drawing.
Term
 Assembly
Definition
 A group of machined or handmade parts that fit together to form a self-contained unit.
Term
 Assembly Drawing
Definition
 A drawing that shows parts of an item when assembled.
Term
 Cartesian Coordinate System
Definition
 A rectangular coordinate system created by three mutually perpendicular coordinate axes, commonly labeled X, Y, and Z.
Term
 Component
Definition
 A part or element of a larger whole.
Term
 Computer-Aided Design or Computer-Aided Drafting (CAD)
Definition
 When used in the context of design: the use of a computer to assist in the process of designing a part, circuit, building, etc. 2. When used in the context of drafting: the use of a computer to assist in the process of creating, storing, retrieving, modifying, plotting, and communicating a technical drawing.
Term
 Degree of Freedom
Definition
 The variables by which an object can move. In assemblies, an object floating free in space with no constraints to another object can be moved along three axes of translation and around three axes of rotation. Such a body is said to have six degrees of freedom.
Term
 Design Brief
Definition
 A written plan that identifies a problem to be solved, its criteria, and its constraints. The design brief is used to encourage thinking of all aspects of a problem before attempting a solution.
Term
 Design Statement
Definition
 A part of a design brief that challenges the designer, describes what a design solution should do without describing how to solve the problem, and identifies the degree to which the solution must be executed.
Term
 Domain
Definition
 The set of input values of a function.
Term
 Extrusion
Definition
 A manufacturing process that forces material through a shaped opening. 2. A modeling process that creates a three-dimensional form by defining a closed two-dimensional shape and a length.
Term
 Function
Definition
 1. A relationship from one set (called the domain) to another set (called the range) that assigns to each element of the domain exactly one element of the range. 2. The action or actions that an item is designed to perform.
Term
 Geometric Constraint
Definition
 Constant, non-numerical relationships between the parts of a geometric figure. Examples include parallelism, perpendicularity, and concentricity
Term
 Marketing
Definition
 The promotion and selling of products or services.
Term
 Mathematical Modeling
Definition
 The process of choosing and using appropriate mathematics and statistics to analyze empirical situations, to understand them better, and to improve decisions.
Term
 Mock-up
Definition
 A model or replica of a machine or structure for instructional or experimental purposes. Also referred to as an Appearance Model.
Term
 Model
Definition
 A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original.
Term
 Origin
Definition
 A fixed point from which coordinates are measured.
Term
 Packaging
Definition
 Materials used to wrap or protect goods.
Term
 Pattern
Definition
 A repeated decorative design.
Term
 Physical Model
Definition
 A physical representation of an object. Prototypes and appearance models are physical models.
Term
 Plane
Definition
 A flat surface on which a straight line joining any two points would wholly lie.
Term
 Portfolio
Definition
 A collection of documents selected for a particular purpose which may contain reflection on the contents of the documents or the related purpose. Varieties of portfolio types exist and are used for different purposes (e.g., project portfolio, course portfolio, longitudinal or growth portfolio, showcase portfolio).
Term
 Prototype
Definition
 A full-scale working model used to test and improve a design concept by making actual observations and necessary adjustments.
Term
 Range
Definition
 The set of output values of a function.
Term
 Revolution
Definition
 Creating a 3D solid or surface by revolving a 2D shape about an axis.
Term
 Rotation
Definition
 Turning around an axis or center point.
Term
 Round
Definition
 A rounded exterior blend between two surfaces.
Term
 Scale Model
Definition
 An enlarged or reduced representation of an object that is usually intended for study purposes.
Term
 Scoring
Definition
 Making an impression or crease in a box blank to facilitate bending, folding, or tearing.
Term
 Solid
Definition
 A three-dimensional body or geometric figure.
Term
 Solid Modeling
Definition
 A type of 3D CAD modeling that represents the volume of an object, not just its lines and surfaces.
Term
 Subassembly
Definition
 An assembled part that is a part of a larger assembly.
Term
 Translation
Definition
 Motion in which all particles of a body move with the same velocity along parallel paths.
Term
 Working Drawings
Definition
 Drawings that convey all of the information needed to manufacture and assemble a design.
