We are designing a new product and have determined the box size to be 3"x3"x3".

We are in the final stages of design and would like a way to dynamically determine the minumum containg box size.

I am currently using a sketch of a side view and drawing a rectangle around the product.

There are 2 dimenstions I am tweeking that change the containing rectangle, but I have to redraw the rectangle every time.

Is there a better way?

Thanks
