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 Orbit toolbar. See “3DOrbit Shortcut Menu” on page 35.
3D Orbit Cursor Icons
View rotation is determined by the placement and appearance of the cursor
as follows:
Circular Arrow
When you move the cursor outside the arcball, it becomes a circular arrow.
Clicking outside the arcball and dragging the cursor around the arcball
causes the view to move around an axis that extends through the center of
the arcball, perpendicular to the screen. This is called a roll.
If you drag the cursor into the arcball it changes to a sphere encircled by
two lines and the view moves freely. If you move the cursor back outside
the arcball, you revert to a roll.
Horizontal Ellipse
When you move the cursor over one of the small circles on the left or right
side of the arcball, it becomes a horizontal ellipse. Clicking and dragging
from either of these points rotates the view around the vertical or Y axis
through the middle of the arcball.
Sphere Encircled by Two Lines
When you move the cursor inside the arcball, it changes to a small sphere
encircled by two lines. If you click and drag in the drawing area you can
move freely around the objects. It works as if your cursor were grabbing a
sphere surrounding the objects and dragging it around the target point.
You can drag horizontally, vertically, and diagonally using this method.
