Specify 3D Views Interactively (3D Orbit) | 153
Note OLE objects and raster objects do not appear in the 3D Orbit view.
2 From the View menu, choose 3D Orbit.
An arcball is displayed within the active viewport. If the UCS icon is on, it
appears shaded. If the
GRID is on, a 3D line grid replaces the 2D dot grid.
3 Click and drag the cursor to rotate the view. When you move your cursor
over different parts of the arcball, the cursor icon changes. The appearance
of your cursor when you click to start dragging indicates the rotation of
the view as follows:
A small sphere encircled by two lines is the cursor icon displayed when
you move the cursor inside the arcball. By clicking and dragging when
the cursor is a sphere you can manipulate the view freely. It works as if
your cursor were grabbing a sphere surrounding the objects and drag-
ging the sphere around the target point. You can drag horizontally,
vertically, and diagonally.
A circular arrow around a small sphere is the cursor icon displayed
when you move the cursor outside the arcball. Clicking outside the
arcball and dragging the cursor around the arcball moves the view
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 small sphere
encircled by two lines and the view moves freely, as described above. If
you move the cursor back outside the arcball, you revert to a roll.
A horizontal ellipse around a small sphere is the cursor icon displayed
when you move the cursor over one of the smaller circles on the left or
right side of the arcball. Clicking and dragging from either of these
points rotates the view around the vertical or Y axis that extends
through the center of the arcball. The Y axis is represented on the
cursor by a vertical line.
A vertical ellipse around a small sphere is the cursor displayed when
you move the cursor over one of the smaller circles on the top or
bottom of the arcball. Clicking and dragging from either of these points
rotates the view around the horizontal or X axis that extends through
the center of the arcball. The X axis is represented on the cursor by a
horizontal line.
