Split 指令旨在以一个物件分割另一个物件。
附注
- 使用 Untrim 指令可以移除曲面的修剪边界。
- 在正对工作平面 的平行视图 (例如：预设的 Top、Front、Right 视图) 以曲线分割曲面时，曲线会往视图的方向投影至曲面上将曲面分割。
- 在非正对工作平面的平行或透视视图 (例如：预设的 Perspective 视图) 中以平面曲线分割曲面时，曲线会往与它的曲线平面垂直的方向投影到曲面上将曲面分割。
- 在非正对工作平面的平行或透视视图中以 3D 曲线分割曲面，曲线会被拉回到曲面上的最近点将曲面分割。
-
To split a polysurface in a non-plan view, if the cutting curve has any portion evaluated as not completely lying on the polysurface, the Split command will fail as designed.
步骤
指令行选项
点 (仅适用于输入物件为曲线的情况)
在曲线上指定分割点。
结构线 (仅适用于输入物件为曲面的情况)
以曲面自己的结构线分割曲面，这个选项只有在被分割的物件是单一曲面时才有作用。
使用交点物件锁点可以锁定曲面结构线的交点。
循环边缘（仅限细分物件）
沿着选定的循环边缘分割细分物件。
步骤
- 选取细分物件。
- 选取循环边缘以分割细分物件。
锐角
指定是否要将分割后的角转化为锐角。
