| A systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to solve or satisfy human needs or wants and to narrow down the possible solutions to one final choice is defined as __________________ | design process |
| A solid modeling technique where geometry is subtracted from existing model geometry. | subtractive modeling |
| A strategy in which geometry is defined in such a way that changes produce desired, predictable results. | design intent |
| A means of judging. A standard, rule, or test by which something can be judged | criteria |
| The result of taking away or removing characteristics from something in order to reduce it to a set of essential characteristics is known as___________ | abstraction |

| A limit to a design process. It may be such things as appearance, funding, space, materials, and human capabilities. | constraint |
| A person who designs any of a variety of things. This usually implies the task of creating drawings or in some ways uses visual cues to organize his or her work. | designer |
| A written plan that identifies a problem to be solved, its criteria, and its constraints. It is used to encourage thinking of all aspects of a problem before attempting a solution. | design brief |

| A solid modeling technique where geometry is added to existing model geometry. | additive modeling |
| A heavy solid line used on a drawing to represent the outline. | object line |
| 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. | design statement |
| A technique for solving problems, generating ideas, and stimulating creative thinking. | brainstorming |
