EG-Easy: Design and Testing of Blender-Based Tool to Teach Projections in Engineering Drawing

Engineering Graphics (EG) is an important course for engineering students at first year level and fundamental course for mechanical, civil or other similar branches. Engineering Graphics problems demand application of spatial ability by students. Computer aided visualizations support spatial ability [3]. Blender based visualizations are designed and tested to develop mental rotation ability which help to improve spatial ability [2]. In our study we have designed blender based tool to develop conceptual understanding for topic of point and line projections. We found that students were able to understand and solve graphic problems faster and with more precision.
