I've got a part (a relatively simple packaging box) that I had previously made by using equations to set certain paramaters (inside length, width, height), but now that I'm learning about design tables I'd like to do it that way instead.  Is there an easy way to get a file like this switched over to using a design table instead so I can easily have multiple configurations (sizes) of the same design for different products?  I had it designed to easily do just that with equations, but I'm not entirely sure how to keep it all in the same file if I do it that way.

Thanks in advance for any help
