The largest box packing algorithm has been introduced for customers that don’t know the dimensions of each product and want to defer to the box that will fit the largest item. Its a low level of accuracy than both best-fit and exact packing but suitable in circumstances where you may have lots of odd items with some of large dimensions.
Firstly you need to put the following attributes into your attribute set on your products (these are installed as part of the extension). Please ensure you add the following attributes to the Shipping subgroup in the relevant Attribute Sets:
Then setup up your boxes that can be used for your products.
In Shipping Settings switch algorithm to Best Fit Packing, and change the tolerance if required (it defaults to 20% allowing for space in the box).
You can configure products in 1 of 2 ways:
- Specify the dimensions of the box the product will fit in (using length, width, height in Shipping tab). The largest set of dimensions is then used as the box and all items that are not set to ship separate or have possible ship boxes specified are packed in this largest box
- Specify the possible ship boxes that can be used for the product. The box that best fits the items is then used for packing. This will restrict the box based on max weight/qty on the box. It does not look at the volume of the individual products (unlike the best-fit algorithm)
You can combine this with the multiple boxes for a SKU and ship separate capabilities.
