    编辑模式

    菜单

    3D视图标题栏 ‣ 选择模式

    快捷键

    1, 2, 3 (Shift , Ctrl 扩展/缩减选择)。

    在 编辑模式下 有三种不同的选择模式。您可通过选择标题栏中三个按钮中的某个来进入不同的选择模式。

    Edit Mode selection buttons from right to left: Vertex, Edge, Face.

    顶点

    In this mode vertices are shown as points. Selected vertices are displayed in orange, unselected vertices in black, and the active or last selected vertex in white.

    边

    In this mode the vertices are not shown. Instead the selected edges are displayed in orange, unselected edges black, and the active or last selected edge in white.

    面

    In this mode the faces are displayed with a selection point in the middle which is used for selecting a face. Selected faces and their selection point are displayed in orange, unselected faces are displayed in black, and the active or last selected face is highlighted in white.

    当使用这些按钮时，可充分利用编辑键，详见： 。

    几乎所有的工具都可以在全部的三种选择模式下使用。所以您在所有的模式下都可以 旋转 ， 缩放 ， 挤出 等。当然，对单个 顶点 进行旋转和缩放是没有意义的(除非 将原点设在了另一个位置)，所以某些工具在某些选择模式下可能更加适用或不太适用。

    不同选择模式示例详见参考图 fig-mesh-select-intro-selection-modes 。

    By holding Shift-LMB when selecting a selection mode, you can enable multiple Selection Modes at once. This allows you to quickly select vertices, edges, or faces, without first having to switch mode.

    当以“升级”的方式(换句话说就是由简单走向复杂)切换选择模式，从 顶点 切换到 边 以及从 边 切换到 面，如果选中元素能构成新的选择模式下的完整元素，其将保持选中状态。

    例如，如果一个面上所有四条边都被选中，由 边 选择模式切换到 面 选择模式下将会保持其构成的面处于被选中状态。所有未能够构成新选择模式下完整元素的内容将被弃选。

    扩展/缩减选择

    By holding Ctrl when selecting a higher selection mode, all elements touching the current selection will be added, even if the selection does not form a complete higher element. Or contracting the selection when switching to a lower mode.

    The X-Ray setting is not just for shading, it impacts selection too. When enabled, selection isn’t occluded by the objects geometry (as if the object was solid).

    All A

    全部选择。

    无 Alt-A

    全不选。

    反转 Ctrl-I

    选择所有未选中的几何图形，并取消选择当前选中的组件。

    框选 B

    交互式框选。

    C

    交互式刷选。

    Lasso Select

    Interactive free-form selection.

    根据百分比随机选择一组顶点、边或面。

    间隔式弃选

    从当前活动项开始间隔性地取消选择数个元素。

    选择锐边

    该工具选择所有相邻面构成夹角大于一定角度值的边，给定角度值越大选中的边越尖锐。

    Shift-G

    选择与当前选中元素相似的元素。

    按特征全选

    通过查询对象特征以选择网格。

    • 扩展选区 Ctrl-数字键盘+

      扩展到当前选择模式下与选中区域相连的区域。

      缩减选区 Ctrl-数字键盘-

      从当前选择模式下选中区域相连的部分缩减选择。

      下一活动元素 Shift-Ctrl-NumpadPlus

      This uses selection history to select the next vertex, edge, or face based on surrounding topology.

      上一活动元素 Shift-Ctrl-NumpadMinus

      选择前一活动元素并取消对最后选择元素的选择状态。

    选择循环

    • 选择相连边。

      面循环

      选择相连面。

      选择相连的并排边。

    选择关联项

    选择活动项的同侧

    选择网格上与活动顶点处于相同单一轴向上的所有顶点。仅限于顶点选择模式。

    Select Mirror Shift-Ctrl-M

    选择指定轴向上镜像位置的元素。

    Selecting dense meshes with X-Ray disabled, has a limitation where dense meshes may not have all the elements selected. When selecting regions with Box, Circle and Lasso select, vertices may overlap each other causing some vertices not to be selected. This is a limitation with the current selection method, you may workaround this by zooming in or enabling X-Ray.

    As already noted, in X-Ray and Wireframe mode faces are marked with a dot in the middle. With n-gons that can lead in certain cases to a confusing display. The example shows the center dot of the U-shaped n-gon being inside of the oblong face inside the “U”. It is not easy to identify which dot belongs to which face (the orange dot in the image is the object origin).
