What's New SOLIDWORKS 2018: Bounding Box

The bounding box is an indispensable piece of reference geometry in SOLIDWORKS, representing the smallest area or volume in which a design can fit. While available in weldment and sheet metal models for many years, creating a bounding box for a standard part has required convoluted workarounds – until now. New in SOLIDWORKS 2018, bounding boxes can be created for standard parts with just a few clicks, enabling you to quickly find the maximum dimensions of your design and use the automatically-generated file properties as needed. To emphasize the utility of the bounding box, an organic shape will be used.

I can't pull out the properties of the bounding box in the assembly specification
Don't know how to do it?

There should be option of "auto dimension" in bounding box command property manager
