On shape to specifications adequacy

Abstract

Computer aided design now aims to provide designers with a support during the early stages of design. The purpose is to translate the client's specifications into a shape as automatically as possible. However, the processing of a text in natural language is still out of reach. We then assume that the client's specifications are manually translated into intermediate specifications composed of intermediate constraints upon physical parameters. Our efforts concern the transformation of these intermediate specifications into a shape, precisely the way to complete whether a shape satisfies the intermediate specifications or not. We first study the case in which the shape is a single primitive solid; we also give elements to choose the instance that best fits the specifications. Then, we study the extension of the method to solids defined by a combination of primitive solids.
