Proportional Editing is a way of transforming selected elements while also affecting the nearby unselected elements. The farther away an unselected element is, the less it will be affected (hence the «proportional»). This feature is very useful for smoothly deforming dense meshes.

Nota

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

Controles

Disable O

Proportional Editing is off, only selected vertices will be affected.

Enable O

Vertices other than the selected vertex are affected, within a defined radius.

Proportional Size

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

Decaimento

While editing, you can change the curve profile by either clicking the Falloff icon in the header or pressing Shift-O to get a pie menu.

Constante, sem decaimento.	Decaimento tipo aleatório.	Decaimento tipo linear.
Decaimento tipo acentuado.	Decaimento tipo raiz.	Decaimento tipo esférico.
Decaimento tipo suavizado.	Decaimento tipo inverso.

Modo de Objeto

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

In the image below, the leftmost cylinder is being scaled up vertically, which also affects the cylinders near it.

Edit Mode

When working with dense geometry, it can become difficult to make subtle adjustments without causing visible lumps and creases in the model’s surface. When you face situations like this, Proportional Editing can help.

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.

Exemplo

The image below shows the final render of a low-poly landscape obtained by moving up the vertices of a triangulated grid with Proportional Editing enabled.
