We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.
有好2种方法：1）先画一个圆面，删除Coverlines（或者选中面右键 -> Edit -> Surface -> Uncover Faces），然后选中圆环右键Edit->Sweep->Around Vector画一个Z轴的方向即可
2）画一个圆柱体，然后选中上下两个面右键->Edit->Surface->Uncover Faces
