The achievement of outcome-based education (OBE) for higher education in engineering is measured by accreditation agencies and relies on the attainment of graduate attributes for the assessment of Program Outcomes, which are measured in the course of Capstone Project in the final year. Cornerstone projects are introduced in preceding years to prepare the students for the Capstone Project. A Cornerstone Project was designed and executed in the fourth semester in a design course to introduce the students to the use of modern 3D CAD tools and the use of Engineering Standards. This paper presents the intervention along with the analysis of the direct evaluation of 184 students and survey-based indirect evaluation of the project by 53% of the students. The effect of this project-based intervention on the student learning for higher order skills, experiential learning, cooperative learning, collaborative learning, and problem-based learning is discussed.
