The upcoming research is to study and search for the answer of the quality and how of the general methods and main structures of drawing geometric decorations. Structures that not only create geometric decorations, but also organize many apparently non-geometric but repetitive decorations that need to be expanded at the level of works of art. Among the most important issues raised in this research is dealing with the issue of what is the necessity of dividing geometric patterns based on drawing structures and how can it be done? Should this division be based solely on the appearance of similarities, or do we need a logical method and a structured and coherent rule for such a matter so that a set of motifs can be categorized by its explanation?, and such a structure How should it be defined? The premise of the research is the existence of two main drawing structures, despite the wide and varied collections of geometric motifs, which can be classified in these main structures with all their variety. The research method is descriptive-analytical and based on studies and library data, as well as extracting and implementing motifs and searching for their drawing method. According to the findings of the research, there are two main structures of drawing in geometric patterns, "grid" or "table" on the one hand, and the style of "Pargari" on the other hand. Although in some cases both structures, especially the filling structure, have been used as an important and main decoration, but in most cases, these two have acted as a sub-main role and based on that. Various and different patterns have been drawn. The aim of this research is to introduce, analyze and search for the similarities and differences of these two structures, based on the implemented examples. The importance of this issue is due to the fact that each of these methods was formed and used in a special historical context, and the analysis of what and how they were formed and the reasons for their importance requires a detailed understanding of the drawing structure. They are in the first step.
