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.

Nota

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

Controles

Desabilitar O, Alt-O: Proportional Editing is off, only selected vertices will be affected.
Habilitar O, Alt-O: Vertices other than the selected vertex are affected, within a defined radius.

Influência

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.

Decaimento

Durante a edição, você pode alterar o perfil da curva utilizado utilizando o ícone de cabeçalho Falloff menu, ou pressionando Shift-O para alternar entre as várias opções.

Object Mode

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 left 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.

Edit Mode

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.

Opções

Connected Only Alt-O: Ao invés de usar apenas um raio, o falloff proporcional se espalha através da geometria conectada. Isto significa que você pode editar proporcionalmente os vértices em um dedo de uma mão sem afetar os outros dedos. Enquanto os outros vértices estão fisicamente próximos (no espaço 3D), eles estão longe seguindo as conexões topológicas das bordas da malha. O ícone terá um centro azul quando Conectado estiver ativo. Este modo só está disponível no modo Edit Mode.

Projected from View: Depth along the view is ignored when applying the radius.
