This paper discusses a new freshman course that merges previous topics in the “Introduction to Mechanical Engineering” and “Engineering Design Graphics” courses into a single integrated teaching effort. The main objective of the new course is to introduce students to mechanical engineering education and practice through lectures and laboratory experiences. A major effort in the course is devoted to a reverse engineering team project. The students are divided into four‐member teams and are instructed to select a simple mechanical assembly for dissection. They study and disassemble their object into basic constituent components, documenting this process with freehand sketches and notes. They use these sketches and other measured dimensions to construct 3‐D solid computer models of each major component. The teams then obtain .STL files of the solid models, which are used to make rapid physical prototypes of their parts. The teams conclude their project activities by generating engineering drawings directly from the 3‐D geometric data base. All of these efforts are integrated, documented, and submitted to the instructor as a final team project report.
