The impact of CAD software on the teaching of engineering graphics: a systematic review

Abstract

Introduction. Incorporating CAD and BIM in the engineering graphics learning environment has revolutionized teaching methods by providing richer visualization, analysis, and collaboration tools. Despite this, there are still big differences in the adoption and ability rates and levels of CAD and BI across regions and institutions. Methods. For PRISMA, 45 studies were used for comparison from 2020-2024. Studies selected for the review had to meet inclusion criteria about CAD and BIM awareness and competency, challenges, and fit within the engineering education curriculum. The data were combined qualitatively and quantitatively, and the discoveries were classified into major themes. Results. CAD applications like AutoCAD are more widely adopted in the BIM industry than in BIM applications like Revit, especially in development areas. Challenges to BIM adoption include high costs, lack of policies, and 2D drafting. Countries with developed BIM industries are the most effective and integrate educational curricula, highlighting the importance of industry alignment in promoting CAD and BIM technologies. Conclusion. This research suggests that frameworks for implementing BIM integration require a uniform set of best practices, more access to information, and demonetization and curriculum development to fill shortcomings. Even with CAD at the core, BIM advances must be looked for following the industry's needs and put into practice. Further research should be directed toward developing ways to overcome and advance the existing technology gaps.
