and Objectives: Visual representations in the form of manuscripts are the most important tools for expressing ideas and generating concepts for designers and architecture students. Its wide application is always considered by designers due to the simplicity of tools and speed of expression. Examining the types and methods of drawing design by students show that each uses a unique method and structure in drawing. An analysis of the concepts underlying the manuscript and identifying the possible

... elationship between graphic expression and personality type is very similar to research on graphology and the relationship between personality and handwriting. graphology is examined in psychology and personality analysis and means the analysis of physical features and handwriting patterns representing the author's personality. Conceptual sketch is the first visual representation of the mental ideas in the process of representation and interpretation embedded on paper, and similar to approaches of line psychology, it reflects many of the mental attributes of the designers and guidance for architecture design professors to understand the students' ability. The research problem is to identify the hidden concepts of conceptual sketch and how different personalities function in problem-solving. Methods: An exploratory descriptive study with an exploratory approach that with direct observation of architectural design and personality test seeks to find out the relationship between the qualities of drawing with personality type. Findings: The sample of the results of the personality and design test shows that perceptual and intuitive personalities have a broader approach to problem-solving ideas and are more skilled in open issues, but they are faced with defective details and lacking a fixed idea. In contrast, logical and judgmental personalities are more powerful in closed issues. They face flaws in detail and fail to come up with a well-established idea, and rational and judgmental personalities are more capable in [...]
