Proportional Edit is a way of transforming selected elements (such as vertices) while having that transformation affect other nearby elements. For example, having the movement of a single vertex cause the movement of unselected vertices within a given range. Unselected vertices that are closer to the selected vertex will move more than those farther from it (i.e. they will move proportionally relative to the location of the selected element). Since Proportional Editing affects the nearby geometry, it is very useful when you need to smoothly deform the surface of a dense mesh.

Note

Blender also has 雕刻 that contains brushes and tools for proportionally editing a mesh without seeing the individual vertices.

装配器

Disable O, Alt-O

衰减编辑关闭，仅所选顶点会受到影响。

Enable O, Alt-O

定义的半径范围内所选顶点以外的顶点受到影响。

影响

You can increase or decrease the radius of the tool's influence during a transform operation with WheelUp, WheelDown or PageUp, PageDown respectively. As you change the radius, the points surrounding your selection will adjust their positions accordingly.

衰减

While editing, you can change the curve profile used by either using the header icon Falloff menu, or by pressing Shift-O to toggle between the various options.

物体模式

Proportional Editing is typically used in Edit Mode, however, it can also be used in Object Mode. In Object Mode the tool works on entire objects rather than individual mesh components.

In the image below, the right cylinder is scaled along the Z axis. When the Proportional Editing is enabled, the adjacent cylinders are also within the tool's radius of influence.

When working with dense geometry, it can become difficult to make subtle adjustments to the vertices without causing visible lumps and creases in the model's surface. When you face situations like this the Proportional Editing tool can be used to smoothly deform the surface of the model. This is done by the tool's automatic modification of unselected vertices within a given range.

选项

仅连接 Alt-O

衰减编辑不光是依据半径，还需要通过相连的几何体传递。 这意味着可以按衰减编辑一只手手指的顶点，而不会影响其他手指。虽然其他顶点在物理上接近（在3D空间中），但它们远离网格的拓扑边连接。当 仅连接 激活时，该图标中心将为蓝色。 此模式仅适用于 编辑模式 。
