This study attempted to revise the 3D-CAD exercises using Onshape in order to improve the rate of achievement of the learning and education goals, and also examined the revisions through actual confirmation work by university students in the author's laboratory, technical staff and junior high school students. The importance of 3D-CAD terms such as entity, sketch, feature, etc. was confirmed with time spent explaining CAD terminology. The achievement rate of the learning and teaching objectives was improved by increasing the number of options for the task execution process, such as chamfering, fillets, offsets, mirrors, and 2D-CAD modification methods by dimensioning. After these revisions, it was confirmed that the course, along with Onshape registration, 3D-CAD terminology, preferences, assembly drawings, and 3D-CAD to 2D-CAD methods, could be completed within 8 weeks, which corresponds to the quota system. As a result of applying the revised version to the “Engineering Design Exercise” for advanced students, it was possible to reproduce the collaborative 3D-CAD exercise. In addition, the number of absent students was eliminated and the rate of achievement of the learning and educational objectives was improved.
