Weld

焊接

The Weld tool can weld several object points or spline points into a single point. Select the points that you want to weld together, choose the Weld tool and click on a point to choose where the welded point will be placed (you will see a highlighted preview appear). If you click elsewhere instead of on one of these points, the welded point will be placed at the center of the selection (again, this is marked by a highlighted preview).

焊接工具可以焊接几个目标点或样条点到一个单一的点。选择要焊接在一起的点，选择焊接工具，并点击一个点，以选择焊接点将被放置在哪里(你会看到一个突出显示的预览出现)。如果你点击其他地方而不是这些点之一，焊接点将被放置在选择的中心(再次，这是一个高亮预览标记)。

Any polygons that become redundant will be deleted automatically.

任何多余的多边形都会被自动删除。

You can use weld with a single selected object or with multiple selected objects. However, keep in mind that the points of different objects cannot be truly welded together.

可以对单个选定对象或多个选定对象使用焊接。然而，请记住，不同物体的点不能真正焊接在一起。

In the example above, two polygons that face each other have been selected (the tool works in all three modes: point, edge and polygon; with edge and polygon mode, all points of the selected edges or polygons will be welded together) and welded together at the position marked by the highlighted point. The result is shown in the inset. In this case, the two cubes are separate objects and the welded point is, in fact, composed of two points in exactly the same place — one point for each object.

在上面的例子中，选择了两个相互面对的多边形(工具在所有三种模式下工作: 点、边和多边形; 在边和多边形模式下，所有选定的边或多边形的点将焊接在一起) ，并在突出显示的点标记的位置焊接在一起。结果显示在插图中。在这种情况下，两个立方体是分开的物体，而焊接点实际上是由位于完全相同的地方的两个点组成的，即每个物体的一个点。

Welding Points with no Active Selection

无主动选择的焊接点

Points that are not currently selected can be welded by clicking on the first point and selecting the second point while simultaneously pressing the Shift (the newly welded point will lie at the mid-point of the welded points) or Ctrl/Cmd (the newly welded point will lie at the position of the second point) key.

当前没有选择的点可以通过点击第一个点并选择第二个点来焊接，同时按下 Shift 键(新焊接的点将位于焊接点的中点)或 Ctrl/Cmd 键(新焊接的点将位于第二个点的位置)。

Splines

样条

In the case of splines, note that points on different segments can only be welded together truly if one is a start point and the other is an end point. Otherwise, the welded points will simply be placed at the same position; they will not be welded into a single point.

在花键的情况下，注意不同部分的点只能真正焊接在一起，如果其中一个是起点，另一个是终点。否则，焊接点将简单地放置在同一位置; 他们不会被焊成一个单一的点。
