A part of 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.
Constant, non-numerical relationships between the parts of a geometric figure. Examples include parallelism, perpendicularity, and concentricity.
A model of an object in which the dimensions are in proportion to the actual dimensions of the object.
Having the dimensions of height and width, height and depth, or width and depth only.
the use of computers, software, and associated hardware for the production of graphic drawings
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.
Also referred to as an Appearance Model. A model or replica of a machine or structure for instructional or experimental purposes.
A number value, or algebraic equation that is used to control the size or location of a geometric figure.
A type of 3D CAD modeling that represents the volume of an object, not just its lines and surfaces. This allows for analysis of the object's mass properties.
a figure whose points do not all lie in a single plane EX: cube, pyramid, sphere...
