Abstract: Spatial visualization skills are crucial in engineering fields and are required to support the spatial abilities of engineering students. Instructors in engineering colleges indicated that freshmen students faced difficulties when visualizing models in engineering graphics. Students cannot correctly understand and process visual object and mental images of the engineering models. Traditional tools using textbooks, physical models, and modeling techniques is not sufficient for improving the spatial visualization skills of engineering students. This paper is a survey of all techniques used to learn freshmen students in engineering graphics and improve their spatial visualization skills. Also, it presents the method of evaluation the spatial visualization skills. After describing techniques and presented the literature review, this work presents a comparison between methodologies and techniques used in previous studies. Finally, we summarize a road of the map for the techniques and strategies to improve the spatial visualization skills for freshmen engineering students.
