How to choose

Use T1 when

All cartons share the same length, width, and height, and you need either the maximum count that fits or the smallest space for a fixed count.

Use T3 when

Several carton sizes are free to rotate and load directly into the container, with no upright-only rule.

Use U3 when

Cargo is palletized or must stay upright, and you need both automated planning and manual adjustment before shipping.

Use RotoSpider when

You are planning mold layouts for rotational molding machine spiders rather than loading cartons or pallets into a container.
