Describes the design and implementation of a prototype working model of an intelligent computer-aided design system (ICADS). States it is the objective of the ICADS project to demonstrate the feasibility of a computer-aided design partnership in which the user orchestrates the evolution of a design solution with the intelligent assistance of the computer. The vehicle for this demonstration is a prototype CAD system shell serving as an intelligent interface between the building designer and a variable assortment of project- related databases and knowledge bases.KEYWORDS: Databases, computer aided design, feasibility, designing.
