| summary |
Design is the computation of shape information that is needed to guide fabrication or construction of an artifact. This information normally specifies artifact topology (connections of vertices, edges, surfaces, and closed volumes), dimensions, angles, and tolerances on dimensions and angles. There may also be associations of symbols with subshapes to specify material and other such properties. The process of design takes different forms in different contexts, but the most usual computational operations are transformations (unary operations) and combinations (binary operations) of shapes in a two-dimensional drawing or a three-dimensional geometric model. An initial vocabulary of shapes, together with a repertoire of shape transformation and combination operators., establishes the shape algebra within which the computation takes place. The computation terminates successfully when it can be shown that certain predicates are satisfied by a shape produced by recursively applying the transformation and combination operators to the initial vocabulary. These predicates are usually stated in symbolic (verbal or numerical) form. Thus determination of whether a predicate is satisfied usually involves producing a numerical or verbal interpretation of a drawing, then deriving inferences from this interpretation by applying rules or formulae. |
