Line Cut

线条切割

The line cut in part replaces the previous Knife tool but can do much more (note also the new Plane Cut and Loop/Path Cut tools that also offer some of the previous Knife tool’s functions).

线切割部分取代了以前的刀具，但是可以做的更多(还要注意新的平面切割和循环/路径切割工具，也提供了以前刀具的一些功能)。

The Line Cut tool cuts both polygonal objects and splines in all three component modes (Use Point, Use Edge, Use Polygon).

线切割工具在所有三种组件模式(使用点，使用边，使用多边形)中同时切割多边形对象和样条。

Note that the cut line does not cut itself. This would create incomplete cuts.

注意，切割线不会自己切割，这会造成不完整的切割。

Use

使用

Click and drag a cut line (or create one using multiple mouse clicks). The cut line can have any number of control points. Additional control points can be added at any time. Simply click on the cut line and a new point will be created.

单击并拖动一条切割线(或使用多次鼠标单击创建一条)。切割线可以有任意数量的控制点。可随时增设管制站。简单地点击切线和一个新的点将被创建。

The cut line will be projected onto the object to be cut from the Viewport’s angle of view. It can snap to polygons, edges or points, or lie freely in space.

切割线将被投影到物体上，从视口的视角切割。它可以贴在多边形、边缘或点上，也可以自由地躺在空间中。

The cut line will remain visible, and therewith editable, in all views until you switch to another tool or press the Esc key. This will complete the cut process.

在切换到另一个工具或按 Esc 键之前，所有视图中的切割线都将保持可见并可编辑。这将完成切割过程。

The cut line will be displayed including several points:

切割线将显示包括几个点:

The following are available:

以下内容可供参考:

• Control points (colored) that can be grabbed and moved 可以抓取和移动的控制点(彩色的)
• Cut points (white) that are automatically created at edge cuts 切点(白色)是自动创建的边缘削减

All control points can be adjusted at any time. The colored points have the following meaning:

所有控制点均可随时调整。彩色控制点有以下含义:

• Yellow 黄色: Control points that lie freely in space : 空间中自由放置的控制点
• Blue 蓝色: Control points that lie on a polygon : 位于多边形上的控制点
• Red 红色: Control points that lie on an edge : 位于边缘的控制点
• Green 绿色: Control points that lie on a vertex : 位于顶点上的控制点
• White 白色: A cut line’s cut points with edges : 有边的切线的切点

As soon as you switch from the perspective view to another view, the cut points will be turned into control points and parts of the cut line that cannot be projected will be hidden.

一旦你从透视图切换到另一个视图，切割点就会变成控制点，无法投影的切割线部分就会被隐藏。

The following hotkeys can be used:

可以使用下列热键:

1. If a control point is moved with the 控件移动控制点时Ctrl/Cmd+Shift 转移 keys pressed, the neighboring cut points will not move. 按下按键，相邻的切点就不会移动
   
2. Shift 转移 +click on a cut line to move a (newly created) control point along a straight section. + 点击切割线移动(新创建的)控制点沿直线部分
   
3. For an existing spline object that at least partially overlaps the object to be cut in the Viewport: Pressing 对于一个现有的样条对象，它至少可以在视窗中相交集切割对象: 按下Ctrl/Cmd+clicking on the spline will project the cut line onto the object and cut it. + 点击样条将项目的削减线上的对象和削减它
   
4. Ctrl/Cmd +click on a control point will delete it. + 点击一个控制点就会删除它
   
5. If the 如果Shift 转移 key is pressed when a cut line’s start or end point is moved, the 当切割线的起始点或终止点移动时，按下Angle Constrain 角度约束 will be taken into consideration. The rotation will be quantized. 都会被考虑在内。旋转将被量子化
