7 **Rotation** feature makes rotation of a selected shape.
9 To create a Rotation in the active part:
11 #. select in the Main Menu *Part - > Rotation* item or
12 #. click |rotation.icon| **Rotation** button in the toolbar
14 Two rotation algorithms are:

30 Rotation by axis and angle

36 Rotation by axis and angle property panel
40 - **Main objects** panel contains shapes to be rotated. Shapes are selected in 3D OCC viewer or object browser;
41 - **Axis** defines the axis of rotation. The vector is an edge or axis selected in 3D OCC viewer or object browser;
42 - **Angle** defines the angle by which the object is rotated.
46 .. py:function:: model.addRotation(Part_doc, [shape], axis, angle)
48 :param part: The current part object.
49 :param list: A list of shapes in format *model.selection(TYPE, shape)*.
50 :param object: An axis in format *model.selection(TYPE, shape)*.
51 :param real: An angle.
52 :return: Rotated object.
57 Result of operation is a rotated initial shape.

62 Rotation by axis and angle
64 **See Also** a sample TUI Script of :ref:`tui_rotation_axis` operation.
66 Rotation by center and points
67 -----------------------------
69 .. figure:: images/Rotation2.png
72 Rotation by center and 2 points property panel
76 - **Main objects** panel contains shapes to be rotated. Shapes are selected in 3D OCC viewer or object browser;
77 - **Center point**, **Start point**, **End point** define 3 points or vertices selected in 3D OCC viewer or object browser. Rotation axis will pass through the **Center point** and will be orthogonal to a plane defined by three points. Rotation Angle is the angle between two vectors directed from the **Center point** to **Start point** and **End point**.
81 .. py:function:: model.addRotation(Part_doc, [shape], point1, point2, point3)*
83 :param part: The current part object.
84 :param list: A list of shapes in format *model.selection(TYPE, shape)*.
85 :param object: An axis in format *model.selection(TYPE, shape)*.
86 :param object: Center vertex.
87 :param object: Start vertex.
88 :param object: End vertex.
89 :return: Rotated object.
94 Result of operation is a rotated initial shape.
