Selection
选择
There are many ways to select elements and it depends on what mode you are in as to what selection tools are available.
blender提供了很多方式去选择组件.这取决于您处于哪种模式以及哪种工具是可行的.
Region selection allows you to select groups of elements within a 2D region. The region can be either a circle or rectangle. The circular region is only available in Edit mode. The rectangular region, or Border Select, is available in both Edit mode and Object mode.
区域选择允许您用2D的区域去选择一些组件.这个区域可以是一个圆也可以是矩形.圆形区域仅仅在(文字|编辑模式)下是可行的.矩形区域,或者说"边框选择",在(文字|编辑模式)和(文字|物体模式)下都是可行的.
Circular region
圆形区域
This selection tool is only available in Edit mode and can be activated with BKEY, BKEY. That is, pressing the BKEY key twice in a row. Once in this mode the cursor changes to a dashed cross-hair with a 2D circle surrounding it. The tool will operate on whatever the current Select mode is. Clicking or dragging with the LMB, when elements are inside the circle, will cause those elements to be selected. You can enlarge or shrink the circle region using NUM+ and NUM- or the MW.
这个选择工具只能用与Edit mode ,您可以用(K|B),(K|B)来激活它.也就是说,按(K|B)两次.按一次后指针变为2D十字虚线,就会进入正确的Select mode 了，点击或托拽与LMB一起应用,如果元件在圆中，那么元件就会被选中。 也可以扩大或缩小圆区域使用 NUM+和NUM- 或 MW.
(Circle Region Select) is an example of selecting edges while in Edge select mode. As soon as an edge intersects the circle the edge becomes selected. The tool is interactive such that edges are selected while the circle region is being dragged with the LMB. (Circle Region Select) 是在Edge select mode中选择边的一个例子，圆形与边交叉，边就会被选择。
If you want to de-select elements either hold MMB or ALT-LMB and begin clicking or dragging again.
如果想取消选择，那么MMB 或 ALT-LMB或者再点或托拽一次。 For faces the circle must intersect the face indicators usually represented by small pixel squares; one for each face.
选择面的时候，圆形交叉面经常会是小像素方形的一个面（←这段翻译有点乱，谁看到帮忙翻译以下）。 To exit this from this tool click RMB or hit the ESCAPE key. 离开圆形区域选择工具点击RMB 或按ESCAPE 键。
Edit Mode
面选择模式
In Face select mode, faces can be selected based on whether they are triangles, quads, or other. Hotkeys:
- CTRL-SHIFT-ALT-3 selects all triangles
- CTRL-SHIFT-ALT-4 selects all quads
- CTRL-SHIFT-ALT-5 selects all non triangle/quad faces.
These tools are also available in both the 3D view header and Toolbox Select menus.
在面选择模式,无论是三角形,方形或其他形状的面都可以选择,热键:
- CTRL-SHIFT-ALT-3 选择所有的三角形
- CTRL-SHIFT-ALT-4 选择所有的方形
- CTRL-SHIFT-ALT-5 选择所有其他的形状
这些工具也可以应用与3D视角和Toolbox Select菜单
Rectangular or Border Select
矩形或边选择
Border Select is available in either Edit mode or Object mode. To activate the tool use the BKEY. Use Border Select to select a group of objects by drawing a rectangle while holding down LMB. In doing this you will select all objects that lie within or touch this rectangle. If any object that was last active appears in the group it will become selected and active.
Border Select 可用于Edit mode or Object mode.使用BKEY激活这个工具. 使用Border Select 选择一个物体的群组，用鼠标加LMB可以选择所有物体.如果一个物体是群组中最后一个被选种的，那么将会是选择＂并＂激活选择． In (Start) Border Select has been activated and is indicated by showing a dotted cross-hair cursor. In (Selecting), the selection region is being chosen by drawing a rectangle with the LMB. The rectangle is only covering cubes "A" and "B". Finally, by releasing LMB the selection is complete; see (Complete).
在(开始) Border Select工具时，会看到一个带有交叉瞄准线的光标， 在(选择)中,选择区域是用鼠标画放行同时按 LMB键选择的.矩形只是遮盖住 "A" 和 "B". 最后，松开LMB 键完成选择；见(Complete).
 Start. |  Selecting. |  Complete. |
Notice in (Complete) that cube "B" is also selected and active. This means that cube "B" was the last active object prior to using the Border Select tool.
| Note:
Border select adds to the previous selection, so in order to select only the contents of the rectangle, deselect all with AKEY first. In addition, you can use MMB while you draw the border to deselect all objects within the rectangle. |
注意：在(Complete)中，方行"B" 也被选择了，也就是说"B" 是使用Border Select 工具最后选择的物体．
