summary	Grammar based production systems are considered potentially powerful design tools by their ability to generate sets of designs adhering to user specified constraints. However, development of such tools has been slow, partly because of the lack of good interaction between user and system. This paper describes modes of user interaction and control possible with grammar based design systems and presents issues to be examined in the development of models that represent the locus of interactions possible with such systems. The examination of existing grammar based systems provides empirical evidence to support the validity of such models.

title	Evaluating the Complexity of CAD Models in Education and Practice
doi	https://doi.org/10.52842/conf.caadria.1999.105
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 105-114
summary	When educators or students estimate the complexity of proposed CAD projects, in order to judge feasibility, two conceptions of complexity may be considered. The first, design complexity, based on visible features of the object to be modelled, is the easier to assess beforehand, but is not very reliable. The second, CAD complexity, based on the actual CAD embodiment of the design, is suggested as potentially a more useful guide, in spite of evident difficulties with assessment in advance. Clearer articulation of this under utilised concept is proposed for both educational and more general reasons, and this becomes the focus of the paper.
