| Question | Answer |
|---|---|
| Annotate | To add explanatory notes to. |
| Assembly Drawing | A drawing that shows the various parts of an item when assembled. |
| Computer-Aided Design or Computer-Aided Drafting (CAD) | The use of a computer to assist in the process of designing a part, circuit, building, etc. The use of a computer to assist in the process of creating, storing, retrieving, modifying, plotting, and communicating a technical drawing. |
| Design Brief | 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. |
| Design Statement | A part of 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. |
| Extrusion | 1. 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. |
| Geometric Constraint | Constant, non-numerical relationships between the parts of a geometric figure. Examples include parallelism, perpendicularity, and concentricity. |
| Logo | An emblematic design adopted by an organization to identify its products. |
| Manufacturer’s Joint | The seam of a carton where the two edges of the box blank are joined together by stitching, gluing, or taping. |
| Marketing | The promotion and selling of products or services. |
| Mock-up | Also referred to as an Appearance Model. A model or replica of a machine or structure for instructional or experimental purposes. |
| Model | A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original. |
| Numeric Constraint | A number value, or algebraic equation that is used to control the size or location of a geometric figure. |
| Origin | A fixed point from which coordinates are measured. |
| Packaging | Materials used to wrap or protect goods. |
| Plane | A flat surface on which a straight line joining any two points would wholly lie. |
| Prototype | A full-scale working model used to test a design concept by making actual observations and necessary adjustments. |
| Scale Model | An enlarged or reduced representation of an object that is usually intended for study purposes. |
| Scoring | Making an impression or crease in a box blank to facilitate bending, folding, or tearing. |
| Solid Modeling | A type of 3D CAD modeling that represents the volume of an object, not just its lines and surfaces. This allows for analysis of the object’s mass properties. |
| Three-Dimensional | Having the dimensions of height, width, and depth. |
| Two-Dimensional | Having the dimensions of height and width, height and depth, or width and depth only. |
