  1. annotate
    To add explanatory notes to a drawing
  2. assembly
    A group of machined or handmade parts that fit together to form a self-contained unit
  3. assembly drawing
    A drawing that shows parts of an item when assembled
  4. Cartesian coordinate system
    A rectangular coordinate system creatd by three mutually perpendicular coordinate axes, commonly labeled X, Y, and Z
  5. component
    A part or element of a larger whole
  6. 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
  7. 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
  8. 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
  9. 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
  10. domain
    The set of input values of a function
  11. 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
  12. 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 range
    • 2. The action or actions that an item is designed to perform
  13. geometric constraint
    Constant, non-numerical relationships between the parts of a geometric figure. Examples include parallelism, perpendicularity, and concentricity
  14. marketing
    The promotion and selling of products or services
  15. mathematical modeling
    The process of choosing and using appropriate mathematics and statistics to analyze empirical situations, to understand them better, and to improve decisions
  16. mock-up
    A model or replica of a machine or structure for instructional or experimental purposes. Also referred to as an Appearance Model
  17. model
    A visual, mathematical, or three-dimensioanl representation in detail of an object or design, often smaller than the original
  18. origin
    A fixed point from which coordinates are measured
  19. packaging
    Materials used to wrap or protect goods
  20. pattern
    A repeated decorative design
  21. physical model
    A physical representation of an object. Prototypes and appearance models are physical models
  22. plane
    A flat surface on which a straight line joining any two points would wholly lie
  23. prototype
    A full-scale working model used to test and improve a design concept by making actual observations and necessary adjustments
  24. range
    The set of output values of a function
  25. revolution
    Creating a 3D solid or surface by revolving a 2D shape about an axis
  26. rotation
    Turning around an axis or center point
  27. round
    A rounded exterior blend between two surfaces
  28. scale model
    An enlarged or reduced representation of an object that is usually intended for study purposes
  29. scoring
    Making an impression or crease in a box blank to facilitate bending, folding, or tearing
  30. solid
    A three-dimensional body or geometric figure
  31. solid modeling
    A type of 3D CAD modeling that represents the volume of an object, not just its lines and surfaces
  32. subassembly
    An assembled part that is part of a larger assembly
  33. translation
    Motion in which all particles of a body move with the same velocity along parallel paths
  34. working drawings
    Drawings that convey all of the information needed to manufacture and assemble a design
