Use the following options to set what happens when you select Modify > Convert > Geometry to Bounding Box.
Specifies the name of the new bounding box object. If you do not specify a name, the bounding box object inherits the name of the original object.
Specifies the name appended to the new bound box object. By default, a _BBox suffix is added to the bounding box Name.
Creates a single instance of a bounding box that represents all objects in the hierarchy.
Creates a bounding box for each object in the grouped object hierarchy.
When One bounding box per shape is on, select this to automatically apply Mesh > Combine to the resulting bounding boxes.
Bakes the original geometry's animation into the resulting bounding box(es). When you use Bake Animation, the resulting bounding boxes transform and scale values are interpolated to maintain the outer boundaries of the original geometry.
Specifies that the Time Slider range determines the duration of the animation that is baked to the bounding box.
Specifies that the range of frames between (and including) the specified Start time and End time times determines the duration of the animation that is baked to the bounding box.
These fields let you specify the start and end time for the animation you bake to the bounding box.
When baking animation to the bounding box, you can set Sample by to specify how often Maya evaluates the animation for the bounding box. For example, a value of 2 specifies that the animation is evaluated every other frame.
