Atração para elementos

A capacidade de capturar (snap) objetos e elementos de malha (mesh) para vários tipos de elementos de cena durante uma transformação está disponível através da troca do ícone do ímã nos botões de cabeçalho do Viewport 3D.

Snap To

Header: Snapping ‣ Snap To
Atalho: Shift-Ctrl-Tab

Incremental: Snap to grid points. When in Orthographic view, the snapping increment changes depending on zoom level.

Nota

In this context the grid does not mean the visual grid cue displayed. Snapping will use the resolution of the displayed grid, but all transformations are relative to the initial position (before the snap operation).
Vertex: Atrair para os vértices do objeto de malha.
Edge: Atrair para as arestas dos objetos de malha.
Face: Snaps to the surfaces of faces in mesh objects; This is useful for retopologizing.
Volume: Snaps to regions within the volume of the first object found below the mouse cursor. Unlike the other options, this one controls the depth (i.e. Z coordinates in current view space) of the transformed element. By toggling the button that appears to the right of the snap target menu (see below), target objects will be considered as a whole when determining the volume center.
Edge Center: Snaps to the middle of an edge. This snap element only pertains to mesh objects.
Edge Perpendicular: Snaps to the nearest vertex in an edge that makes a perpendicular angle. This snap element only pertains to mesh objects.

Dica

Multiple snapping modes can be enabled at once by Shift-LMB the different snapping elements.

As opções de snap ficam ativas quando Vertex, Edge, Face, ou Volume é selecionado como o elemento snap. Estes determinam que parte da seleção se encaixa (snaps) nos objetos alvo.

Ativo(a): Move o elemento ativo (vértice no Edit Mode, objeto no Object Mode) para o alvo.
Mediano: Moves the median of the selection to the target.
Center: Moves the current transformation center to the target. Can be used with 3D cursor to snap with an offset.
Mais próximo: Moves the closest point of the selection to the target.

Additional Options

As seen by the yellow highlighted areas in the image above, besides the snap target, additional controls are available to alter snap behavior. These options vary between mode (Object and Edit) as well as Snap Element. The four options available are:

Absolute Grid Snap: Disponível apenas para a opção de aumento. Snap to grid, em vez de snap in incrementos em relação à localização atual.

Backface Culling: Exclude back facing geometry from snapping.

Project Onto Self: Snaps elements to its own mesh. Available only in editing mode for Vertices, Edges, Faces and Volume. Not available when Proportional Editing is enabled.

Alinha a rotação com o alvo de atração: Available for Vertices, Edges, Faces and Volume. When the Snap Affects Rotation, this align rotation with the snapping target.

Project Individual Elements: Disponível para snap to Faces. Projeta elementos individuais na superfície de outros objetos.

Snap Peel Object: Disponível para snap to Volume. Considera os objetos como um todo durante a localização do centro do volume.

Deslocamento: Limits the effect of the snap to the transformation type.

Múltiplos alvos de atração

Once transforming a selection with Snapping on (not just when holding Ctrl), you can press A to mark the current snapping point, then proceed to mark as many other snapping points as you wish and the selection will be snapped to the average location of all the marked points.

Marking a point more than once will give it more weight in the averaged location.
