Visual expression and/or presentation evaluation course, which stands among the basic courses of Interior Architecture and Environmental Design/Interior Architecture education and is considered as the course in which the final results of expression by drawing -the common language of the majority of professional courses- are taken, constitutes the main focus of this study. Although the course may have different names in different universities, it is usually given under the names as visual 'presentation' or 'expression', used in the same meaning. This course, which may be included in the curriculum as elective or compulsory, includes the methods and techniques of presentations of the designed space/product. Considering the history of Interior Architecture and Environmental Design/Interior Architecture education, it can be observed that the tools and techniques used, change in time. In this field, learning by doing and experiencing are important. Model making and drawing methods, which have been frequently used, constitute the basic content of the presentation techniques course. It is seen that in Interior Architecture, various media and programs, being used for technical drawings and modeling, can also be applied in the preparation of presentations. Using only 2-dimensional expressions in the education process may become insufficient over time. In this sense, trying to learn 3D thinking by doing/experimenting with manual techniques would not only increase the quality of students' work, but also may help them to create a sustainable awareness. In order to discuss this issue, the main purpose of this study, planned as a descriptive qualitative research, is to transfer 2.5 dimensional studies -a cross- section between 2 and 3 dimensions-, and to make a comparative analysis with 2 and 3 dimensional studies through these transfers. With this purpose, the results of a work conducted within the course, 'Visual Expression Techniques' at Hacettepe University, Faculty of Fine Arts, Department of Interior Architecture and Environmental Design are presented. The outputs obtained are discussed in terms of contribution to the field and current practices.
