Rotating an Object in 3D
The 3D Rotate command is another command that is like an extension of its 2D counterpart.
With 3D Rotate, a Rotate gizmo appears that restrains the rotation about the X, Y, or Z axis.
You don't need to perform these steps as an exercise. You can try the command on your own
when you need to use it.
Here's how it works:
1.
Choose Modify
3D Operations
3D Rotate on the menu bar. You can also enter
3DROTATE
↵.
2.
Select the object or objects you want to rotate and then press ↵. The Rotate gizmo appears
on the object (Figure 20.71).
