Box Selected Calculates the aspect ratio of the current selection’s bounding
box, and then displays the
Render Bounding Box/Selected dialog on page 5907
, which lets you specify a width and height for the rendering, and provides
the option of maintaining the aspect ratio.
Region Selected When an object or objects are selected, renders those objects
and other objects within the selection's bounding boxes, but does not change
the rendering outside the bounding boxes.
