The data in the figure is made using the initial Subdivision tool when the Alias Subdivision function section was tested in 2019, and has not been modified since then. Then, when I participated in the Autodesk Automobile Manufacturing Cloud Salon in 2022, due to the need of PPT documents, I combined Sketch to make this part of the illustration. When making the data in the illustration, it is completely constructed with reference to the effect diagram, and then the produced data is put on several sketches. When making the work picture, there are some problems in the perspective matching of the work picture because of the conflict between the project and the activity time. Please spray it lightly, thank you! For more information, please pay attention to "Saiwen Auto" WeChat subscription number
