Onshape の押し出し機能を用いた基礎製図課題の実践と効果2024 · The authors attempted to create a manual on mechanical design drafting and 3D-CAD operation using Onshape for elementary and junior high school students. The manual was reviewed through actual verification work carried out by junior high school students and university students in the author’s laboratory. By utilizing Onshape’s extrusion function, basic drafting tasks in the field of mechanical design and drafting, such as cylinders, V-shaped blocks, and connecting rods, were constructed. These drawings of cylinders, V-shaped blocks, and connecting rods were combined with Onshape account registration, setup, printing 2D-CAD drawings from 3D-CAD drawings, and assembly drawings to complete a total of seven lectures. This corresponds to a quarter system (a 4-term system). The results of the study confirmed that even junior high school students who cannot read three-view diagrams can learn how to operate Onshape if an operation manual is prepared for them. Furthermore, the effectiveness of the system was verified by employing the operation manuals and basic drafting assignments created in the engineering design exercises.
Onshapeによる機械設計製図と3D-CADの遠隔講義課題の検討2023 · The selection criteria and the selection results of a distance learning assignments on “mechanical design and drafting” considering the “Corona disaster” and assignments by using Onshape, such as the Shako vise and manual winch are studied, were examined through the actual confirmation work by the students in the author’ s laboratory. It was found that Onshape was effective for distance lectures on mechanical design and drafting, and for providing an environment for conducting collaborative assignments. However, it also became clear that there are technical issues to consider when using Onshape to perform the drafting of a classic manual winch. The actual lecture management was conducted in collaboration with the university’s technical staff. The effectiveness of the collaborative lecture by the teaching staff and technical staff is described.
