ABSTRACT
The traditional view of CAD in architectural design is changing. This view rested on a fundamental premise which was that demarcations between different kinds of design task could be modularised. Once design tasks were identified, the characteristics of each task would be analysed by particular resources provided by different pieces of software. In the past history of CAD, once differentiation between tasks took place, the problem was always one of linking them together again, so that a totality of tasks could be applied to particular projects. This segregation and then reintegration led to the development of large and cumbersome CAD environments with a wide range of modular components.
