Precision¶
Reference
| Mode: | Object and Edit Modes |
|---|---|
| Hotkey: | Ctrl and/or Shift |
Holding Ctrl during a transform operation (such as move, rotate or scale) will toggle Transform Snapping. When the Snap Element is set to Increment, this allows the transformation to be performed in discrete amounts.
Holding Shift during a transform operation will transform the object at 1/10th the speed, allowing much finer control.
The magnitude of the transformation can be viewed in the 3D View header. Releasing Ctrl or Shift during the transformation will cause the movement to revert back to its normal mode of operation.
Note
The snapping behaviors described on this page only apply when Increment Snap is selected.
Tip
It is possible to enable both snapping and precision mode, simply hold Ctrl and Shift. This has the following effects:
- Move
- Changes in 0.1 unit increments, regardless of zoom level.
- Rotation
- Changes in 1 unit increments.
- Scale
- Changes in 0.01 unit increments.
Usage¶
With Hotkeys¶
Press G, R or S and then hold either Ctrl, Shift or Shift-Ctrl.
With the Transform Gizmo¶
Hold Ctrl, Shift or Shift-Ctrl and click on the appropriate gizmo handle. Then move the mouse in the desired direction. The reverse action will also work i.e. clicking the gizmo handle and then holding the shortcut key for precision control.

Tip
Combining with Other Controls
All of the precision controls detailed on the page can be combined with the Axis Locking controls and used with the different Pivot Points.
Snapping¶
Move¶
One unit (default zoom level).
Snapping while moving objects changes the object location in 1 unit increments. While in an aligned view, The increment amount is changed based on the zoom level. For example, at a base zoom level objects are moved in increments of 1 unit (i.e. between the two light gray lines). Zooming in enough to see the next set of gray lines will snap in increments of 1/10 of a unit. Zooming in further until will snap in increments of 1/100 of a unit and so on until the zoom limit is reached. Zooming out will have the opposite effect and cause movement to happen by increments of 10, 100 units, etc.
Rotation¶
Holding Ctrl will cause rotations of 5 degrees.
Scale¶
Holding Ctrl will cause size changes in increments of 0.1 units.
Note
Snapping modes
Note that if you have a Snap Element option enabled, holding Ctrl will cause the selection to snap to the nearest element.

Precision¶
Holding Shift during transformations allows for very fine control that does not rely on fixed increments. Rather, large movements of the mouse across the screen only result in small transformations of the selection.
In rotation mode the selected element will be rotate in 0.01 degree increments.
