Research QuestionResearch Question

Can we program “Can we program “DESIGN STYLEDESIGN STYLE” ” into into a set of “a set of “RULESRULES” ?” ?

If so, can we “If so, can we “USE THE RULESUSE THE RULES” to ” to develop a “develop a “GENERATIVE CAD GENERATIVE CAD

SYSTEMSYSTEM” ” which expresses the design which expresses the design style? style?
