This paper discusses information flow between knowledge-based models and shape grammars for generation of building designs, explaining the interaction, system and implementation. The benefit for using the interactive system is that the complementary properties of the two schemes are used to strengthen the overall process. Shape grammar contains rules about the geometric organization, while knowledge-based model supports the contextual information.
