ABSTRACT

In this paper presents some preliminary work done on the Architectural 
Design Assistant. The function and structure of the Design Assistant 
are presented along with some of the motivation behind its development. 
A building design model, as well as its manipulation are discussed.
The role of the National Building Code of Canada is outlined and the 
latter sections of the paper present an example of how this code is 
incorporated into the Design Assistant. One of the most important aspects 
of the Design Assistant - the use of high level abstraction - is 
highlighted as of the example.
