Rotates or turns the view so that you can see your model from a different perspective.
If you have objects selected, Smart 3D rotates about the center of those objects. If nothing is selected, the software rotates
about the center of the view.
For precision needs, you can define the angle and an incremental step value. To view
objects in the model from a different angle, use the Rotate View 
command instead.
To use this command, select an object, and click Rotate Object . Then, specify the axis of rotation by a point (the axis position point) and a direction.
You can also relocate the position point for the axis of rotation, if necessary.
After defining the axis of rotation and position point, define the angle of rotation. One way to define the angle is by moving the mouse in a drag-and-drop operation. Another way to define the angle is to type a value in the Angle box. You can also specify a Step value that represents an incremental angle value. A third way to define the angle is by comparing and changing the angle between a reference plane or line on the rotation object with a reference plane or line on a stationary object in the model. In this mode, you use the Reference on Rotation Object and Reference on Stationary Object buttons on the ribbon.
-
If the component has more than one constraint, you cannot rotate it. If the object is not fully constrained, you can rotate it at any time.
-
If the object has a mate relationship to a surface, you can only rotate the object about the axis that is perpendicular to the surface, which the software selects by default. The default point of rotation is the origin of the object.
-
If you are rotating structural members, be sure to select all the members and the coordinate system that you want to rotate. If you select just the coordinate system, the members will rotate but the rotation angle of the members themselves will not change.
