The use of computers in architectural design had its infancy in the early 1960's, however, its potential has and is taking longer to realise than was first thought. New approaches to design coupled with dramatic reductions in the price of hardware have increased the range and applicability of computers in architecture. Today we are witnessing the introduction of computer-aided drafting systems into offices. Work in the areas of building modelling, design methods and knowledge engineering all indicate that the future use of computers in design could well be substantial.
