Building facades in Iranian cities are being designed and constructed incoherently and without patterns, and the originality of Iranian architectural culture is being forgotten. In this design, using the 3D Isovist technique, different derivatives such as facade components, golden proportions, forms used in Safavid architecture, and paintings and art are used to show the view of the building facades, which is the Manifestation of world. An example has been used in Safavid architectural decorations to design and explain the pattern of building facades. This process can be summarized in the following 4 steps:

Step 1: Facing the observer with the building facade
This stage consists of four scenarios: the first scenario sees the viewer of the facade width , the second scenario sees the observer of the facade height, the third scenario sees the observer of the facade grid, the fourth scenario is the distance of the observer to the building facade.

Step 2: Visible observer volume
At this stage, the observer in the urban environment sees a part of the building facade that is emitted by his eye rays and a part is not seen due to the presence of cars and trees, which by calculating the triple integral of the building view volume minus the view volume integral Cars and trees. The visible volume of the observer from the facade is completely determined and is quantifiable.

Step 3: Find the visual preferences of the observer with the Isovist technique
At this stage, with the 3D Isovist technique and regression models, we find the visual preferences of the observer over the visible volume of the observer, and we suggest the best facade frame in terms of facade components and golden proportions.

Step 4: Design a pattern extracted with works drawn by Iranian artists from the world of example
After extracting the building facade pattern based on Isovist technique and aesthetic preferences and adapting it in the form of golden proportions, we use the Safavid garden plan form to design the facade details and the paintings of the imaginary world and the Shiite example as the facade material and color.
And this process solves the problem of patternlessness in the design and execution of building facades of Iranian metropolises.
