2026 ASEE Annual Conference & Exposition

For this Great Idea for Teaching (and talking with students) (GIFT) presentation, we present the Reverse CADding activity designed for first-year undergraduate engineering students who are a part of Society of Manufacturing Engineers (SME) Chapter at our institute. This activity develops essential skills in engineering graphics and computer aided design (CAD) modeling through a reverse engineering approach. In our introductory engineering graphics course, in collaboration with the Society of Manufacturing Engineers (SME), students are tasked with deconstructing a physical part—a ZEISS Coordinate Measuring Machine (CMM) calibration block—and translate it into a digital 3D model using SOLIDWORKS. Through this activity, students learn precise measurement techniques using calipers, micrometers, dial indicators, depth gauges, protractors and angle measurement tools. Additionally, students gain an understanding of design intent, manufacturability and the functional role of components in mechanical assemblies. This activity integrates the three Cs of Entrepreneurial Mindset Learning (EML): curiosity, making connections between design and manufacturing processes and creating value through design improvements. By analyzing real-world parts, students assess design choices, consider manufacturing constraints, and propose enhancements for performance, cost-effectiveness, or manufacturability. The assessment criteria include creating a CAD model (part and drawing) and discussing the challenges faced during measurement and modeling. This teaching idea not only reinforces CAD proficiency but also promotes critical thinking, creativity and an entrepreneurial approach to real world problem-solving. Additionally, it can be adapted for courses related to additive manufacturing.
