| Term | Definition |
|---|---|
| Annotate | To add explanatory notes to a drawing |
| Assembly | A group of machined or handmade parts that fit together to form a unit |
| Assembly Drawing | Drawings showing parts of an item when assembled |
| Cartesian Coordinate System | A rectangular coordinate system created by three perpindicular axes, labeled X,Y, and Z |
| Component | A part or element of a larger whole |
| Computer-Aided Design | The use of a computer to assist in the process of designing a part, circuit, building, etc. |
| Degree of Freedom | The variables by which an object can move, usually around three axes of movement |
| Design Brief | A written plan that identifies a problem to be solved, its criteria, and its constraints. |
| Design Statement | A part of a design brief that challenges the designer, describes what a design solution should do without describing how to solve the problem |
| Domain | The set of imput values of a function |
| Extrusion | A modeling process that creates a three-dimensional form by defining a closed two-dimensional shape and a length |
| Function | 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. |
| Geometric Constraint | Constant, non-numerical relationships between the parts of a geometric figure such as parallelism, perpendicularity and concentricity. |
| Marketing | The promotion and selling of products or services |
| Mathematical Modeling | The process of choosing and using appropriate mathematics and statistics to analyze empirical situations, to understand them better, and to improve decisions. |
| Mock-up | 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. |
| Origin | A fixed point from which coordinates are measured. |
| Packaging | Materials used to wrap or protect goods. |
| Pattern | A repeated decorative design |
| Physical Model | A physical representation of an object. Prototypes and appearance models are physical models. |
| Plane | A flat surface on which a straight line joining any two points would wholly lie. |
| Portfolio | A collection of documents selected for a particular purpose which may contain reflection on the contents of the documents or the related purpose. |
| Prototype | A full-scale working model used to test and improve a design concept by making actual observations and necessary adjustments |
| Range | The set of output values of a function |
| Revolution | Creating a 3D solid or surface by revolving a 2D shape about an axis. |
| Rotation | Turning around an axis or center point. |
| Round | A rounded exterior blend between two surfaces |
| 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 to facilitate bending, folding, or tearing |
| Solid | A three-dimensional body or geometric form |
| Solid Modeling | A typ0e of 3D CAD modeling that represents the volume of an object, not just its lines and surfaces. |
| Subassembly | An assembled part that is a part of a larger assembly |
| Translation | Motion in which all particles of a body move with the same velocity along parallel paths |
| Working Drawings | Drawings that convey all of the information needed to manufacture and assemble a design. |
