Note that the rotate gizmo remains visible through the base point and the angle of
rotation selections. The rotated object is shown in Figure 8-9B.
If you need to rotate an object on an axis that is not parallel to the current X, Y, or
Z axes, use a dynamic UCS with the
3DROTATE
command. Chapter 4 discussed the
benefi ts of using a dynamic UCS when creating objects that need to be parallel to a
surface other than the XY plane. With the object selected for rotation and the dynamic
UCS option active (press the
[Ctrl]+[D]
key combination), right-click and select
Relocate
Gizmo. Make sure the
Respect Dynamic UCS
option is checked. Then, move the rotate
gizmo over a face of the object. The gizmo aligns itself with the surface so that the Z
axis is perpendicular to the face. Carefully place the gizmo over the point of rotation
using object snaps. Make sure the tool is correctly positioned before picking to locate
it. Then, enter an angle or use polar tracking to rotate the object about the appropriate
axis on the gizmo.
PROFESSIONAL TIP PROFESSIONAL TIP
By default, the move gizmo is displayed when an object is selected with no command
active. To toggle between the move gizmo and the rotate gizmo, select the grip at the
tool’s origin and press the space bar. Then, pick a location for the tool’s origin. You can
toggle back to the move gizmo using the same procedure.
