Abstract: Computer-aided design tools which are available currently have been providing effective
support for the later stages of the architectural design process. For the initial stage of architectural
design, in which design concept is mature whereasthe structure and shape are not determined, a new
kind of solution should be needed to support designers way of thinking and inspire the creation of
design. Thus, in this paper, a new method of architectural generation based on shape grammar is
proposed to describe the animation of the complex 3D forms. It tells how to create an initial shape by
limited rules, then automatically generate genetic shapes, and finally grow into a complex system by
modifying the adaptable rule. Also, the developed shape grammar framework allows designers to
actively participate in the generation process. Finally, the modeling of CFS wall prototype is taken as an
example to verify the effectiveness and practicality of this method.
