Snapping

拍照

Snapping is the positioning of an element at a predefined location on another element (e.g., vertices, edges, guides, temporary guides, layers, etc.). There are numerous ways of using the Snapping feature for positioning objects or vertices when modeling.

抢拍是将一个元素定位在另一个元素上的预定义位置(例如，顶点、边、向导、临时向导、层等)。在建模时，有许多种方法可以使用 Snapping 特性来定位对象或顶点。

If Snapping is enabled, elements to be moved will snap to others that lie within the defined radius (Snap Radius).

如果启用了“捕捉”功能，要移动的元素将与定义半径(捕捉半径)内的其他元素捕捉到一起。

Snapping works primarily in conjunction with the Move tool but can also be used with other tools and functions (e.g., Polygon Pen, Spline Pen, etc.). Snapping does not work in conjunction with parametric objects’ Handles, Deformers, etc.

抢拍工作主要与移动工具结合，但也可以与其他工具和功能(如，多边形钢笔，样条钢笔等)一起使用。捕捉不能与参数对象的手柄、变形等一起工作。

Component Snapping

组件抢购

During interactive snapping, each component of each object that lies beneath the cursor to which you can snap is highlighted:

在交互式抓拍过程中，你可以抓拍的光标下面的每个对象的每个组件都会被高亮显示:

If you have selected multiple components (vertices, edges or polygons) and want to move these using the Move tool, click and drag one of the elements; continue to press the mouse button and drag the element over possible snapping points; release the mouse button when you have positioned the element as desired. All other selected elements will be moved with the element on which you clicked and dragged. If you click and drag in an empty region, the center point of the selected elements will be used as the pivot point.

如果您已经选择了多个组件(顶点、边缘或多边形) ，并希望使用 Move 工具移动这些元素，请单击并拖动其中一个元素; 继续按鼠标按钮并拖动元素到可能的断点上; 当您将元素定位到所需位置时，请释放鼠标按钮。所有其他选定的元素将随着您单击并拖动的元素一起移动。如果在空白区域中单击并拖动，则选定元素的中心点将用作枢轴点。

Object Snapping

对象捕捉

Follow these steps if you want to snap the points of an entire object (does not work with Primitives):

如果你想抓取整个对象的点，按照下面的步骤操作(对 Primitives 不起作用) :

• In the 在Snap 啪 settings, set the mode to 设置，将模式设置为Point 重点, for example. ，例如
• Press and hold the 按住L hotkey to temporarily switch to the Enable Axis mode (if the axis is not moved, the object’s origin will be used as the pivot point). 热键临时切换到启用轴模式(如果轴没有移动，对象的原点将用作枢轴点)
• Click on the corresponding point of the object to be moved (which will then serve as the pivot point) to reposition the object at this location. 单击要移动的对象的对应点(该点将作为枢轴点) ，以在此位置重新定位对象
• Release the L key to exit the Enable Axis mode. 释放 l 键退出 enableaxis 模式
• Switch to the Move tool and drag the pivot point (including the object) to the position to which you want it to snap. Done. 切换到 Move 工具，并将枢轴点(包括对象)拖动到您希望它停止的位置。完成

UV Snapping

紫外线捕捉器

When editing UV elements in the Texture UV Editor, snapping also works for the respective tools there (e.g., move, rotate, UV Transform). If desired, a grid can be displayed (UV Grid) to which you can also snap.

当在纹理 UV 编辑器中编辑 UV 元素时，拍照也适用于相应的工具(例如，移动，旋转，UV 变换)。如果需要，一个网格可以显示(UV 网格) ，你也可以单元。

You can snap to the following nearest elements (the options of the same name can be enabled in the Snapping settings):

你可以捕捉到以下最近的元素(可以在捕捉设置中启用相同名称的选项) :

• Vertex 顶点: UV points : 紫外线点
• Edges 边缘: UV edges : UV 边缘
• Mid Point 中点: UV edge mid points : UV 边缘中点
• Grid Point 网格点: Grid intersection points : 网格交叉点
• Grid Line 网格线: Grid lines : 网格线
• Pixel Snap 像素捕捉: Texture pixels (s. : 纹理像素(s)

If Snapping is enabled in Polygon mode, the cursor will snap to the next point on the selection on the UV Island to be edited and will then be used as the pivot or anchor point (e.g., rotation point for the Rotate tool) when the mouse button is released.

如果在多边形模式下启用了捕捉，光标将会卡在要编辑的 UV 岛上选择的下一个点上，然后当鼠标按钮被释放时，光标将被用作枢轴或锚点(例如，旋转工具的旋转点)。

As long as the cursor has not yet snapped to an element during editing it will be displayed with a small cross. If it can snap to a UV element (or grid), its appearance will change as follows:

只要光标在编辑过程中还没有被捕捉到一个元素，它就会显示一个小叉。如果它可以捕捉到 UV 元素(或网格) ，它的外观将改变如下:

As long as nothing is snapped to, the cursor will appear as a cross; after snapping to a point (or edge mid point or texture pixel) it will appear as a circle and as a double line on an edge.

只要没有被抓拍到，光标就会显示为一个十字; 抓拍到一个点(或边缘中点或纹理像素)之后，光标就会显示为一个圆形或边缘上的一条双线。

This lets you see exactly and intuitively where the UV element will be placed.

这使您能够准确而直观地看到 UV 元素将放置在哪里。

If you grab the selection approximately at the center, the pivot/anchor point will be placed at the center of the selection.

如果您大致在中心抓取选定内容，那么枢轴/锚点将被放置在选定内容的中心。

This works the same in Point and Edge mode.

这在点模式和边模式下也是一样的。

Dynamic Guides and Reference Points

动态指南及参考点

Completely new in Cinema 4D are the dynamic guides that automatically generate temporary guides around important vertex positions (e.g., object origin, translation type, etc.) or defined reference points.

在 Cinema 4D 中完全新的是动态指南，它能自动生成围绕重要顶点位置的临时指南(例如，物体原点，翻译类型等)或定义的参考点。

Example:

例子:

You want to move 4 selected vertices of the cube at the right in a parallel direction to the same height as the front side of the cube on the left (the following workflow is for demonstration only - this can actually be solved much faster using the Perpendicular Snap command).

您希望将多维数据集的4个选定顶点在右侧平行移动到与左侧多维数据集正面相同的高度(下面的工作流程仅供演示——使用“垂直管理单元”命令实际上可以更快地解决这个问题)。

Follow these steps:

遵循以下步骤:

• Select the Move tool and enable the Snap modes 选择移动工具并启用管理单元模式Vertex, Intersections, Guides and Dynamic Guides 顶点，交叉点，指南和动态指南.
• Click and drag on the top-left vertex and drag it to the top-right vertex of the left cube (2.) and hover for about 0.5 seconds; continue to press the mouse button. 单击并拖动左上角顶点，并将其拖动到左立方体(2.)的右上角顶点然后盘旋0.5秒，继续按鼠标键
• Drag to the vertex at the left rear of the cube on the right and hover for about 0.5 seconds. You have now set 2 reference points. 拖动到立方体左后方的顶点，在右侧盘旋约0.5秒。你现在已经设置了两个参考点
• Drag back in the direction of the original vertex. A blue guideline (Z axis) will automatically be created (if both cubes did not lie parallel to the global axis the guideline would be neutral in color) along which you can move your selection. 向原始顶点的方向拖回。将自动创建一个蓝色指南(z 轴)(如果两个数据集不平行于全局轴，则指南的颜色为中性色) ，您可以沿着该指南移动所选内容
• A red guide (X axis) will be displayed at the height of the first reference point. Snap the selection to the 在第一个参考点的高度将显示一个红色指南(x 轴)。将所选内容对齐到Intersection 十字路口 point of both guides. Done. Remember, this entire process was completed while continuously pressing the mouse button! 两个导轨的顶点。完成。记住，整个过程是在不断按下鼠标键的同时完成的

Because Snapping also works with other important tools it is also possible to create many types of projected cut lines with the Line Cut tool, as shown here:

因为斯坦普还可以和其他重要工具一起工作，所以也可以使用线切割工具创建多种类型的投影切割线，如下图所示:

All you have to do is correctly position the guides. The Dynamic Guides (Vertex and Dynamic Guides are enabled here) will take care of the rest.

你所要做的就是正确定位导游。动态指南(顶点和动态指南启用这里)将照顾其余。

1. Drag the Knife tool along the Dynamic Guides that are located along the polygon edge.

1. 沿着位于多边形边缘的动态向导拖动刀具。

2. The Perpendicular mode is also enabled.

2. 垂直模式也已启用。

Dynamic Guides are displayed in definable angles (by default 90°, which is parallel to the working plane axes) parallel to the working plane (with exception of the vertical plane) around the following locations:

动态导轨以可定义的角度(默认为90 ° ，与工作平面轴线平行)与工作平面平行(垂直平面除外)显示在以下位置:

• The point at which the move is initiated (this is the object axis for objects in Use Model and similar modes) 启动移动的点(这是 Use Model 和类似模式中对象的对象轴)
• Maximum any two reference points (the guides’ connecting line will also be displayed as a guide). 任意两个参考点的最大值(参考线也会显示为参考线)
• At any other useful location. 在任何其他有用的地点

Dynamic Guides will also be displayed here:

动态指南也将显示在这里:

• At the 3 axes at the starting point of the move (marked as a green cross) with regard to the working plane AND the object axis system (or at the modeling axis in the component mode) 在移动起始点的3个轴上(标记为绿色十字) ，与工作平面和物体轴系有关(或在组件模式的建模轴上)
• All straights that lie on a connected edge of a polygonal object’s selected vertex (or reference point) in Use Point mode 在使用点模式下，所有位于多边形物体选定顶点(或参考点)的连接边上的直道
• All straights between the selected vertex (or reference point) of a linear Spline in Use Point mode and the next or previous Spline vertex. And also at the straight between the start or end vertex of an open linear Spline to the next respective point. 使用点模式下线性样条的选定顶点(或参考点)与下一个或前一个样条顶点之间的所有直线。并且也在开放线性样条的起点或终点到下一个相应点之间的直线上

Guides can be generated temporarily on snappable object vertices (Vertex Snapping must also be enabled and 3D Snapping is also recommended in most cases) by hovering over such a vertex for at least 0.5 seconds (depending on the tool used, this must also be done with the moue button pressed, e.g., for the Polygon Pen tool). The reference point will then be marked with a circled cross. A maximum of 2 reference points can be marked at the same time; if a new one is added, the previously created one will be deleted. These points will disappear when you switch tools.

指南可以临时生成的可快速对象顶点(顶点抢购也必须启用和3D 抢购也建议在大多数情况下)悬停在这样的顶点上至少0.5秒(根据所使用的工具，这也必须与鼠标按钮按下，例如，为多边形钢笔工具)。然后，参考点将用一个圈起来的十字标记。最多可以同时标记两个参考点; 如果添加了一个新的参考点，以前创建的参考点将被删除。当你转换工具的时候，这些点就会消失。

It can happen that so many Dynamic Guides and Intersection points are created that you lose oversight of what’s going on in your Project (each of these purple Intersections points can be selected and each will display information about the corresponding Guides):

它可能会发生如此多的动态指南和交叉点被创建，以至于你失去了对项目进展的监督(这些紫色交叉点中的每一个都可以被选中，每一个都会显示相应指南的信息) :

If you lose oversight it’s probably because you simply have too many Snap options enabled. Consider carefully, which ones you really need and disable the others.

如果你失去了监督，这可能是因为你有太多的 Snap 选项启用。仔细考虑哪些是你真正需要的，然后禁用其他的。

The purple cross is generated by the enabled Intersections option, which displays possible intersections around the cursor’s current position.

紫色十字是由激活的 interutions 选项生成的，它显示了光标当前位置周围可能的交叉点。

The Perpendicular option can also result in numerous "hits" and should only be enabled if you really need it.

垂直选项也可以导致大量的“命中” ，应该只启用如果你真的需要它。
