薄片沿长度连续扭转

提示词

让选定薄片沿自身长度连续转面，保留可追踪的两侧边缘和相邻片间隙；扭转发生在片体上，不把整片刚体旋转、重复波纹或相互熔连当作同一种形态。

Let the selected thin elements twist continuously along their own length, keeping both side edges traceable and adjacent elements separated. The twist belongs to each element itself, rather than being replaced by whole-element rigid rotation, repeated corrugation or fused elements.
