 annotate To add explanatory notes to a drawing assembly A group of machined or handmade parts that fit together to form a self-contained unit assembly drawing A drawing that shows parts of an item when assembled Cartesian coordinate system A rectangular coordinate system creatd by three mutually perpendicular coordinate axes, commonly labeled X, Y, and Z component A part or element of a larger whole computer-aided design or computer-aided drafting (CAD) 1. When used in the context of design: the use of a computer to assist in the process of designating 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 degree of freedom 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 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 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 domain The set of input values of a function extrusion 1. A manufacturing process that forces material through a shaped opening2. A modeling process that creates a three-dimensional form by defining a closed two-dimensional shape and a length function 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 range2. The action or actions that an item is designed to perform geometric constraint Constant, non-numerical relationships between the parts of a geometric figure. Examples include 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. Also referred to as an Appearance Model model A visual, mathematical, or three-dimensioanl 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 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 blank to facilitate bending, folding, or tearing solid A three-dimensional body or geometric figure solid modeling A type of 3D CAD modeling that represents the volume of an object, not just its lines and surfaces subassembly An assembled part that is 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 Authorhdong135 ID183721 Card SetInt.
