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
