Description

Rotation is also known as a spin, twist, orbit, pivot, revolve, or roll and involves changing the orientation of elements (vertices, edge, face, Object etc) around one or more axes. There are multiple ways to rotate an element which include:

The keyboard shortcut (R)
The 3D manipulator widget
The Properties menu (N)

Basic rotation usage and common options are described below. For additional information, you may wish to read the Transform Control and Orientation pages which provide more information about options such as Precision, Axis Locking, Numeric Input and Snapping.

Usage

Rotation using the keyboard shortcut

Use RMB to select the elements you want to rotate.
Tap R once to enter rotation mode.
Rotate the elements by moving the mouse. The closer the mouse is to the elements's center, the higher the rotation influence.
LMB click to accept changes.

The amount of rotation will be displayed in the bottom left hand corner of the 3D window.

Rotation values

Constraining the rotation axis (axis locking)

Rotation can be constrained to a particular axis or axes through the use of Axis Locking. To constrain rotation, the following shortcuts can be used:

R, X: Rotate only along the X Axis
R, Y: Rotate only along the Y Axis
R, Z: Rotate only along the Z Axis

Fine Tuning The Rotation

Precise control can be had over rotation through the use of the ⇧ Shift and Ctrl keys to limit rotation to discrete amounts. You can also entering a numerical value in degrees to specify the amount of rotation after after initiating a rotation transformation.

Hold Ctrl down while performing a rotation to rotate the selected element in 5 degree increments.
Hold ⇧ Shift down while performing a rotation to rotate the selected element in 0.01 degree increments.
Hold ⇧ ShiftCtrl down while performing a rotation to rotate the selected element in 1 degree increments.
Press R, type in a number and press ↵ Enter to confirm.
Press R,R to enable Trackball rotation.

	Orientation dependant rotations
	By default, all rotations happen around a Global Orientation. You can change the rotation orientation by pressing the axis key twice. For example, pressing R, X, X will by default set rotation to occur around the local orientation.

Rotation with the 3D Transform Manipulator

Rotation Transform Manipulator

In the 3D View header, ensure that the Transform Manipulator is enabled (the red, green, and blue triad is selected). Set the manipulator type to rotation (the highlighted arc icon shown below).

Select your element with RMB .
Use LMB and drag any of the three colored axes on the rotation manipulator to rotate your object along that axis. You can also use ⇧ Shift, Ctrl or numeric input with the 3D manipulator widget for further control.
Your changes will be applied when you release LMB or press Space or ↵ Enter. Your changes will be cancelled if you press RMB or Esc.

Rotation with the Properties Panel

Rotation transform properties panel.

Rotation values can also be specified in the Properties panel (N) by altering the degree value in the rotation slides of the Transform panel. Rotation along particular axes can be enabled or disabled by toggling the padlock icon. The rotation mode (Euler, Axis Angle, Quaternion) can also be set in this panel from the drop down box.
