area, and click Other Navigations Modes Free Orbit (2).
Summary
Selecting one of more objects before starting this command limits the display
to those objects only.
While the command is active, right-click to display additional options from
a shortcut menu.
3DFORBIT activates a 3D Free Orbit view in the current viewport. If the user
coordinate system (UCS) icon is on, a shaded 3D UCS icon representing the
current UCS appears in the 3D Orbit view. You can view your entire drawing
or select one or more objects before starting the command.
The 3D Free Orbit view displays an arcball, which is a circle divided into four
quadrants by smaller circles. When the Enable Orbit Auto Target option is
deselected in the shortcut menu, the target of the view stays stationary. The
camera location, or point of view, moves around the target. The center of the
arcball, not the center of the objects youre viewing, is the target point. Unlike
3DORBIT, 3DFORBIT does not constrain the change in view to prevent roll,
the rotation of the view about an axis orthogonal to the plane of your screen.
NOTE You cannot edit objects while the 3DFORBIT command is active.
Moving your cursor over different parts of the arcball changes the cursor icon,
indicating the direction in which the view rotates. See 3D Free Orbit Cursor
Icons
on page 31.
While the command is active, you can access additional 3DORBIT options
from a shortcut menu by right-clicking in the drawing area, or choosing
buttons on the 3D Navigation toolbar. See
3D Orbit Shortcut Menu on page
39.
TIP While in 3D Orbit mode, you can temporarily enter 3D Free Orbit mode by
pressing and holding the Shift key.
