Augmented reality (AR) is a growing technology that superimposes 3D images onto the real world. This enhances the user’s real-world experience. This potential of AR can be utilized effectively in teaching learning for engineering graphics courses. There is visualization limitation for engineering students entering the first year, and this leads them to face difficulty in understanding and developing orthographic, isometric, and section view of models. AR can empower the students to visualize the actual virtual object in a 3D view to match their imagination with the augmented object. In this regard, initially, a framework of AR is conceptualized for the course of engineering graphics, and an AR application is developed. This paper mainly focuses on the investigation and impact of AR technology on interactive teaching learning processes in engineering graphics. The impact of this technology is measured by student performance in an AR interactive test. The result shows an increase in student performance in written test by 18.52% in engineering graphics and in a mental rotation test by 28.97%.
