In order to produce practical CAD applications for schematic design we must explore the computer’s potential as a form of expression and its role as a graphic medium. An examination of the use of traditional graphic media during schematic design will provide some clues regarding what capabilities CAD must provide and how a system should operate in order to be useful during conceptual design.
Such a problem, in standard form, presents an objective function Z=f(x), of n variables x, to be minimized and a system of linear equations and/or inequalities, on the same variables, which represent the constraints and which define an admissible area for the solution.
The architectural organism is modelled as an assembly of parallelepiped shaped space entities or units, provided with a certain number of "holes" that permit functional corresponding connection. The pursued intent being optimal assembly.
The model, in its mathematical form, fits a standard Non-Linear M.P. (N.L.P.) problem, since the objective function Z is non-linear and the constraints are represented by inequalities. In its graphic form it reproduces an image of all the space units constituting the organism; moreover it is able to represent these units, in their logical and physical individuality, and their mutual relationship, as well as the ones with the external environment.
Web-based digital libraries and indexes of literature have been available on the internet for a few years now. In many cases a focus on specified areas is given and published information is disseminated in this way. However, researchers, educators and practitioners in architecture and civil engineering also depend on various sources of information that are stored and delivered in a multitude of media formats. Some of that information is case-based and built incrementally from previous experiences.
