The place of "shapes grammar" in architecture

Nowadays, the importance of the design process has reached a point where many experts say that the importance of the design process is equal to the design product. Design is often considered subjective and inspired, and observing the process that architects go through to achieve the ossification of a design always remains in a state of ambiguity. In this way, answers to questions such as Where do the designs come from? Or how can the design process emerge through an objective approach? It is simply not possible, and even diagrams and ideograms, despite expressing some ideas, are incomplete in their full realization. The possibility of visual reading of hidden ideas in the mind is one of the most important issues facing architects and the shapes grammar as a kind of law-based systems based on geometric changes, causes the analysis and production of multiple answers by extracting visual rules and developing them in different stages. The present study, with the help of data collected from library studies and comparing this data with the process used to produce the design, tries to introduce the shapes grammar as a type of rule-based design processes, which have the ability to generate various answers. Suggest analytical methods in shapes grammar to understand the design path and observe the process of project formation. In order to better answer this question, first the fields of introduction of grammatical attitudes into the academic and the architectural profession are discussed, then the process and steps of using shapes grammar are mentioned along with examples of analysis of architectural works. Finally, among the three approaches, analytical, design and combination, the analytical approach to the shapes grammar will be introduced as a rule-based process in architectural design and a method for visual representation and objective emergence of design formation process. Also, if the design approach to the shapes grammar is combined with analysis and the rules extracted from a particular place or style are changed, and then the foundation of a new style is laid, a combinatorial approach is formed. We will be able to produce a new grammar by relying on the existing grammar and changing its rules. This attitude can also be effective in developing existing designs.
