3 Drag the mouse on and around the trackball to produce different types of view rotations. The cursor changes to indicate the type of rotation in effect: ■ To rotate the view freely within the viewport, drag inside the trackball. The free rotation continues while dragging even if the cursor crosses outside the trackball. ■ To constrain the rotation to the horizontal or vertical axis, drag the trackball handles. Drag horizontally on the side handles, or vertically on the top or bottom handle. ■ To rotate the view about the depth axis that is perpendicular to the screen, drag outside the trackball. When the cursor crosses inside the trackball during dragging, free rotation occurs. When the cursor crosses back outside the trackball, spinning rotation is again in effect. 4 To exit the Orbit function, press Esc or right-click within the viewport. To constrain rotation to a single axis: ■ Hold down the Shift key as you rotate. The rotation is constrained to the first axis you use. To rotate with keyboard and mouse: ■ Hold down the Shift key as you rotate. The rotation is constrained to the first axis you use. Interface Orbit Uses the view center as the center of rotation. If objects are near the edges of the viewport, they might rotate out of view. Orbit Selected Uses the center of the current selection as the center of rotation. The selected object remains at the same position in the viewport while the view rotates around their center. Orbit SubObject Uses the center of the current sub-object selection as the center of rotation. The selection remains at the same position in the viewport while the view rotates around its center.
