Snapping lets you easily align objects and mesh elements to others. It can be toggled by clicking the magnet icon in the 3D Viewport’s header, or more temporarily by holding Ctrl.

Snapping ‣ Snap To

快捷键

Shift-Ctrl-Tab

Determines the target which the selection will be snapped to.

增量

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

Note

By default, this option won’t snap to the grid that’s displayed in the viewport, but an imaginary grid with the same resolution that starts at the selection’s original location. In other words, it lets you move the selection in “increments” of the grid cell size.

If you want to snap to the viewport grid instead, you can enable Absolute Grid Snap (see below).

顶点

Snaps to the nearest vertex of a mesh object.

边

Snaps to the nearest point on the nearest edge.

Face Project

Snaps to the face by projecting the current point on the nearest face. This snap mode will snap geometry to both visible and occluded. This snap mode is useful for retopologizing.

Snaps to the nearest surface in world space. This snap mode will only snap geometry to visible (non occluded) geometry.

体积光渲染

Snaps to regions within the volume of the first object found below the mouse cursor. Unlike the other options, this option controls the depth (i.e. Z coordinates in current view space) of the transformed element. By toggling Snap Peel Object (see below), target objects will be considered as a whole when determining the volume center.

边中点

Snaps to the centerpoint of the nearest edge.

垂直交线

Snaps to a specific point on the nearest edge so that the line from the selection’s original location (indicated by a white cross) to its new location is perpendicular to that edge.

Tip

Multiple snapping modes can be enabled at once using Shift-LMB.

吸附 ‣ 吸附基准点

快捷键

Shift-Ctrl-Tab

Determines what part of the selection will coincide with the target. (The rest of the selection will follow along.)

活动

Snaps using the origin (in Object Mode) or center (in Edit Mode) of the active element.

质心

Snaps using the median of the selection.

中心

Snaps using the current transformation center (another word for the pivot point). This option is especially useful in combination with the for choosing the snapping point completely manually.

最近

Snaps using the vertex that’s closest to the target.

As seen in the yellow highlighted area 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 target. The available options are:

Only available in Edit Mode. Allows snapping mesh elements to other elements of the same mesh.

This checkbox is ignored if is enabled.

Include Edited Edit Mode

Snap onto non-active objects in Edit Mode.

Include Non-Edited Edit Mode

Snap onto objects not in Edit Mode.

Exclude Non-Selectable

Snap only onto objects that are selectable.

绝对栅格吸附

Only available if Snap To Increment is enabled. Snaps to the grid, instead of snapping in increments relative to the current location.

背面剔除

Exclude back-facing geometry from snapping.

将旋转与吸附目标对齐

Rotates the selection so that its Z axis gets aligned to the normal of the target.

投射到独立元素

Only available if Snap To Face is enabled. Rather than the default behavior where only the “Snap With” point gets snapped to the target and the rest of the selection follows along (maintaining the original shape), this option makes each object (in Object Mode) or vertex (in Edit Mode) snap to a target independently of the others, which may cause the selection’s shape to change.

This can be used for bending a flat sheet so it snugly fits against a curved surface, for example.

Snap to Same Target Face Nearest

Snap only to target that source was initially near.

Face Nearest Steps Face Nearest

Number of steps to break transformation into for face nearest snapping. This option is only available in Edit mode.

吸附剥落物体

Only available if Snap To Volume is enabled. Consider objects as a whole when finding volume center.

Specifies which transformations are affected by snapping. By default, snapping only happens while moving something, but you can also enable it for rotating and scaling.

While you’re transforming a selection with snapping enabled, you can press A whenever there’s a highlighted snap target to mark it. With multiple such targets marked, the selection will then be snapped to their average location.

Marking a target more than once will give it more weight.
