While using 3D Free Orbit, the cursor changes as it is moved to indicate how the model will be orbited when clicking and dragging.
View rotation is determined by the placement and appearance of the cursor as follows:
- 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 is grabbing a sphere surrounding the objects and dragging it around the target point. You can drag horizontally, vertically, and diagonally using this method.
- 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.
- 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.
- Vertical Ellipse
-
When you move the cursor over one of the small circles on the top or bottom of the arcball, it becomes a vertical ellipse. Clicking and dragging from either of these points rotates the view around the horizontal or X axis through the middle of the arcball.
