Set light sources for illuminating graphics. Lighting settings control the location, direction, and intensity (high/low)
of the specular lighting. The Multi-light CAE and Multi-light CAD options have predefined configurations.
Using the mouse button and keyboard strokes assigned to the Vertical Zoom
function, click in the animation or model window.
Drag the mouse vertically on the screen.
As the mouse is dragged upward, the graphic is reduced within the
window. As the mouse is dragged downward, the graphic is enlarged to fill the
window.
